Prism

A World of Warcraft Forever addon that makes action buttons respond visually to gameplay situations.

Features

General

All glows require a ready action cooldown. The global cooldown does not hide glows. Consumable glows also require at least one carried use. Bank items do not count. Highlights and red warnings ignore the carried count. Highlights and red warnings do not require cooldown readiness. Every visual follows the button opacity, including fades from the parent bar.

• Combo-point numbers: Eviscerate, Slice and Dice, Expose Armor, Rupture, Kidney Shot, and Rip show the current target's combo-point count. The centered green number has a thick black outline and no background. Its size follows the button size. The number requires at least one point, a usable action, a ready spell cooldown, and no matching aura highlight. The global cooldown does not hide the number. Five-point glows use separate conditions.
• Racial buffs: Shadowmeld, Elune's Light — Highlights while the player has the action's buff. Target selection and action usability do not affect the highlight.
• Item buffs: Highlights an item while the player has a helpful aura with the same ID as the item's use spell. This includes Night Watchman's Torch. Target selection and action usability do not affect the highlight. Different aura IDs and passive equipment buffs require explicit rules.
• Bandages: Highlights bandages while the heal target is alive and has full health. A usable bandage blinks red while the heal target has a poison debuff.
• Healing potions: Highlights healing potions while the player is alive and has full health. The current target and action usability do not affect the highlight.
• Mana potions: Highlights mana potions while the player is alive and has full mana. The current target and action usability do not affect the highlight.
• Poison cleansing: Anti-Venom, Strong Anti-Venom, Powerful Anti-Venom, and Potent Anti-Venom. Each item glows while a carried use remains and the heal target has a poison debuff, regardless of action usability. This bypasses incorrect client usability results for Anti-Venom only. Each item highlights while the heal target has no poison debuff, regardless of action usability.
• Disease cleansing: Simple Poultice, Clever Poultice, Superior Poultice, and Powerful Poultice. Each item glows while a carried use remains, the action is usable, and the heal target has a disease debuff. Each item highlights while the heal target has no disease debuff, regardless of action usability.

Spell actions require explicit aura rules. Shared aura rules cover the declared racial buffs and automatic item buff matching. Druid aura highlights and ranked Rogue aura highlights accept the same or stronger rank. Vanish accepts every declared Stealth rank and both improved stealth auras. Warrior and Hunter use their explicit mechanics and the shared rules. Undeclared spell actions receive no automatic buff highlight.

Warrior

• Own target debuffs: Rend — Highlights while the target has the player's debuff.
• Shared target debuffs: Hamstring, Demoralizing Shout, Thunder Clap — Highlights while the target has the matching debuff.
• Shared target debuff stacks: Sunder Armor — Highlights when fully stacked.
• Tanking: Taunt, Mocking Blow, Challenging Shout — Highlights while the player tanks the target.
• Usable attacks: Execute, Overpower, Revenge, Victory Rush — Glows while the spell is usable.
• Interrupts: Shield Bash — Glows during a hostile target cast or channel while the spell is usable.
• Fear warning: Intimidating Shout — Blinks red while the spell is usable and the hostile target has Rend or Deep Wound from any caster.

Hunter

• Own target debuffs: Serpent Sting — Highlights while the target has the player's matching debuff.
• Shared target debuffs: Hunter's Mark, Concussive Shot, Wing Clip, Scorpid Sting, Viper Sting — Highlights while the target has the matching debuff from any caster.
• Sting replacement warning: A usable Serpent Sting, Viper Sting, or Scorpid Sting blinks red while the target has the player's different sting. Another hunter's sting does not activate the warning.
• Usable attacks: Mongoose Bite, Counterattack — Glows while the spell is usable.
• Threat reduction: Disengage — Glows while the player tanks a living hostile target and the action is usable.
• Pet healing: Mend Pet — Highlights while the player's living pet has full health. The highlight does not require a usable action.
• Pet feeding: Feed Pet — Highlights while the living pet is Happy or has the Feed Pet Effect buff. Action usability does not affect the highlight. Glows only without the buff, while the action is usable and the living pet is below Happy and out of combat.
• Pet revival: Revive Pet — Highlights while the player's pet is alive. The highlight does not require a usable action.

The client exposes three pet happiness states. Feed Pet uses the highest state, Happy, not an exact happiness percentage. The active Feed Pet Effect buff suppresses the glow and keeps the highlight.

Rogue

Rogue rules cover every rank of the supported abilities. Highlights do not require a usable action. Glows require a usable action. Combo points refer to the current target.

• Eviscerate: Glows at exactly five combo points.
• Slice and Dice: Highlights while an equal or stronger buff is active.
• Expose Armor: Highlights while an equal or stronger target debuff is active.
• Rupture: Highlights while the target has the player's equal or stronger bleed.
• Garrote: Highlights while the target has the player's equal or stronger bleed.
• Stealth, Sprint, Evasion: Highlight while their matching player buffs are active.
• Vanish: Highlights during normal Stealth or Vanish's improved stealth. Target selection, usability, and cooldowns do not affect the highlight. Glows at 20% health or less while the player is alive, in combat, and the action is usable. The glow is independent of the stealth highlight.
• Shank: Glows in combat while usable if the full energy gain fits after the current energy cost. Each rank includes the active Flash of Steel bonus. The limit follows maximum energy and current cost changes. The check does not predict natural energy regeneration or test combo points and Venom.
• Cheap Shot, Kidney Shot, Gouge, Sap, Blind: Highlight while their matching target debuffs are active.
• Riposte: Glows while the action is usable. Highlights while the target has Riposte's disarm from any caster. The disarm highlight does not suppress the glow. Usability and cooldowns do not affect the highlight.
• Kick, Gouge, Kidney Shot: Glow during a living hostile target's cast or channel.
• Feint: Glows in a party or raid while the player tanks a living hostile target.
• Instant Poison: Each poison item rank glows while usable if either equipped melee weapon has no poison. Item macros receive the same glow through the application spell ID, including macros with bare #showtooltip. Prism does not treat raw macro IDs as item IDs. Any poison rank counts on either weapon. The crafting spells receive no poison reminder. Empty slots, shields, and held items do not require poison. Permanent enchants and non-poison coatings do not count as poison.
• Sinister Strike, Backstab: Glow with the Remorseless buff and fewer than five combo points.
• Pick Pocket, Throw: Receive no Rogue-specific feedback.

Cheap Shot and Blind accept their matching target debuffs from any caster. Both Kidney Shot ranks accept either stun rank from any caster. Gouge, Sap, and Expose Armor accept equal or stronger aura ranks from any caster. Cast glows do not check interruptibility or control immunity. Remorseless Attacks grants the Remorseless buff.

Druid

Druid aura highlights accept the action rank or a stronger rank within each declared spell family. A weaker rank does not activate these highlights. Caster filters still apply. Different spell families remain separate, even when their effects are similar.

• Buff highlights: Mark of the Wild, Thorns, Regrowth, Rejuvenation, Abolish Poison. Each spell highlights while the heal target has an equal or stronger rank from any caster.
• Player-only buffs: Dash, Enrage, Nature's Grasp, Prowl — Each button highlights while its matching buff is active on the player. Target selection and action usability do not affect these highlights.
• Own target debuffs: Moonfire, Rip, Rake — Highlights while the target has the player's matching debuff.
• Finisher glow: Rip — Glows at exactly five combo points on the current target while usable and without the player's matching bleed. An equal or stronger own bleed suppresses the glow and keeps its highlight, regardless of action usability.
• Energy feedback: Shifting Power — Highlights while the living player has full energy, regardless of action usability. Below full energy, a usable action blinks red if its 40-energy gain exceeds the player's missing energy. Both conditions follow the player's maximum energy.
• Shared target debuffs: Entangling Roots, Bash, Demoralizing Roar, Faerie Fire, Hibernate, Soothe Animal. Each button highlights while the target has the matching debuff from any caster. Entangling Roots also matches the auras from Nature's Grasp. Action usability does not affect these highlights.
• Tanking: Growl, Challenging Roar — Highlights while the player tanks a living hostile target. Action usability does not affect the highlight.
• Taunt glow: Growl — Glows in a party or raid while the player does not tank a living hostile target. The action must be usable. A target without threat data also activates the glow.
• Missing target debuff: Faerie Fire — Glows while the action is usable and a living hostile target lacks an equal or stronger debuff. Any caster's equal or stronger rank suppresses the glow. The debuff highlight remains independent of action usability.
• Threat reduction: Cower — Glows while the action is usable and the player tanks a living hostile target.
• Interrupts: Bash — Glows during a hostile target cast or channel while the spell is usable.
• Healing: Healing Touch, Regrowth, Rejuvenation — Highlights while the heal target is alive and has full health. Action usability does not affect the highlight. Regrowth and Rejuvenation keep their independent buff highlights.
• Curse cleansing: Remove Curse — Glows while the action is usable and the heal target has a curse debuff. The button highlights while the heal target has no curse debuff, regardless of action usability.
• Poison cleansing: Abolish Poison — Glows while the action is usable and the heal target has a poison debuff. The button highlights while the heal target has no poison debuff, regardless of action usability. The active buff also keeps its independent highlight.
• Self-buff glow: Mark of the Wild, Thorns — Each spell requires a usable action. The spell glows when the player lacks an equal or stronger buff and is the heal target. Another assistable target disables the glow. A weaker buff activates the glow. Any caster's equal or stronger buff suppresses the glow.

Installation

• Download Prism from CurseForge.
• Extract Prism into the Interface/AddOns/ directory for the Forever client.
• Restart WoW, or type /reload if the game is open.

Architecture

The main file selects the shared rules and the current class rules. The core contains no class-specific branches. Class files compose tested mechanics through rule tables and small Lua helpers. They contain no frame operations or gameplay callbacks.

File	Responsibility
Rules.lua	Provides rule helpers, validates declarations and rank lists, and resolves glow dependencies.
Core.lua	Implements action matching, mechanics, visuals, secure aura containers, placement, and refresh control.
Shared.lua	Defines class-independent rules and item IDs.
Classes/Warrior.lua	Defines Warrior spell IDs, aura IDs, and feedback rules.
Classes/Hunter.lua	Defines Hunter spell IDs, aura IDs, and feedback rules.
Classes/Rogue.lua	Defines Rogue spells and feedback rules.
Classes/Druid.lua	Defines Druid spells, ordered ranks, related aura IDs, and feedback rules.
Prism.lua	Selects the rules and starts the core.

The TOC loads these files in that order. Add each class file after Shared.lua and before Prism.lua in Prism.toc.

Rules

Each rule defines a unique key, an action selector, a condition, and a visual.

Action selectors match spell IDs, item IDs, or item categories. Spell selectors also match the base spell ID. anySpell matches all spell actions. anyItem matches all direct item actions. Item selectors require a direct item action and a positive item ID. A raw macro ID does not identify an item, even when GetActionInfo returns an item subtype. C_TooltipInfo.GetAction reports an item macro as Macro data without an item ID. Macro actions match declared spell selectors through C_ActionBar.GetSpell. An item macro can expose an application spell through this path. That application spell needs an explicit rule. Prism does not infer item IDs from application spells. Prism does not parse macro text or tooltip text. A change to the resolved item or spell updates the feedback on the regular refresh interval. Aura filters use declared IDs or the spell IDs selected by the condition.

Keep action IDs separate from aura IDs. Set includeActionSpellID only when the spell action can also identify the aura. This flag requires a spell selector and adds only the current spell action ID. Set includeItemSpellID to add the item's use spell ID from C_Item.GetItemSpell. This flag requires an item selector. Neither flag infers triggered effects, spell families, or ranks. If item data is not cached, the core requests it and retries on later refreshes. A missing use spell produces an empty ID filter unless the condition declares other IDs. An empty ID filter admits no aura. Use auraSpellIDs without includeItemSpellID for an explicit item mapping. Several rules can apply to one action. Each aura rule uses a separate secure container for its filter and alpha.

Set auraSpellIDsByAction to provide a separate aura ID set for each action ID. The map must cover the selector's spell IDs. It cannot accompany auraSpellIDs. The core selects the map entry for the current action or its base spell. Rules.RankedAura builds these maps from class declarations. The core needs no global spell catalog. Rank matching compares declared ranks, not live aura amounts or talent bonuses. The client selects active auras through secure filters. Addon Lua does not read aura data to compare ranks.

Mechanic	Condition
aura	A matching buff or debuff is active on the selected unit.
aura-stacks	A matching aura reaches the specified application count.
dispel-type	A matching debuff is active on the selected unit, or absent when invert is true.
alive	The selected unit exists and is alive.
full-health	The selected unit exists, is alive, and has full health.
low-health	The living player has at most the declared health percentage.
full-mana	The selected unit exists, is alive, and has full mana, regardless of its active power type.
full-power	The living player has full power of the declared type.
power-overflow	The declared power amount exceeds the living player's missing power, unless excludeFull excludes full power.
power-gain	The living player can receive the declared power gain without waste after the current spell cost.
combo-points	The player has exactly the declared count on the current target. Without a count, the rule only adds the number.
pet-happiness	The living pet matches the declared happiness state or is below it when below is true.
missing-weapon-enchant	An equipped main-hand or off-hand weapon has none of the declared enchantments.
usable	The action is usable.
self-target	The heal target is the player.
target-cast	A living hostile target casts or channels.
hostile-target	The target exists, is hostile, and is alive.
tanking	The player tanks the living hostile target, unless invert is true.

The unit can be player, pet, target, heal-target, or buff-target. The heal target is an assistable current target, or the player if no assistable target exists. The buff target is the heal target for helpful spells that are not self-only buffs. Self-only buffs and other spells select the player. The core uses C_Spell.IsSpellHelpful and C_Spell.IsSelfBuff to select the buff target. Use buff-target only for helpful aura conditions with a spell selector.

Set requireUsable on a rule to require a usable action. This modifier also applies to target-cast rules. Set requireCombat on a rule with a non-aura condition to require player combat. The validator rejects requireCombat = true for aura, aura-stacks, and dispel-type conditions. Combat events refresh these visuals immediately. Set comboPointsBelow on a plain aura condition to require a lower combo-point count on the current target. The limit must be a positive integer. Restricted counts hide the visual. The limit changes the container alpha. It does not disable the aura slot or change its filters. The limit also gates number suppression for a finisher highlight. Do not combine this limit with suppressGlow. Set points on a combo-points condition to require an exact positive count on the current target. An action with a combo-points rule also receives one numeric overlay, independent of the rule's exact count. A combo-points rule with visual = "none" omits points and adds only the number. Such a rule takes no requireUsable or requireCombat, because the rule has no visual to gate. The number requires a positive count, a usable action, and no active spell cooldown. It ignores the global cooldown. A matching plain aura highlight hides the number while active. An invisible glow suppressor does not hide the number. Secure aura groups move the number outside the viewport. Addon Lua does not read highlight visibility. Restricted combo-point counts hide both visuals. Set percent on a low-health condition to set the inclusive player health limit. The percentage must be an integer from 1 to 100. Maximum health must be positive and unrestricted. The threshold follows changes to maximum health. The client compares health through a step curve. Addon Lua does not read the player's current health. Set powerType on a full-power condition to test the living player's declared power resource. The maximum must be positive and unrestricted. Set powerType and a positive integer amount on a power-overflow condition to test player power waste. The threshold follows maximum power. Restricted maximum power values do not activate the visual. Set excludeFull to prevent a power-overflow visual at full power. Set powerType and a positive integer amount on a power-gain condition to test a spell's power gain. This mechanic requires a spell selector. The core subtracts the current cost from C_Spell.GetSpellPowerCost before it tests the gain. The client compares current power through a step curve. Addon Lua does not read current power. Set talentNodeID and a positive integer amountPerRank together to add a talent bonus to the gain. The core reads the talent rank from the active configuration. Missing talent data or staged changes to that node hide the visual. Missing spell data and restricted costs also hide the visual. A cached spell without resource costs uses a zero cost. The limit follows maximum power, cost, and talent changes on the regular refresh interval. Set outOfCombat on a pet-happiness condition to require the pet to be out of combat. Set enchantIDs on a missing-weapon-enchant condition to declare the accepted weapon enchantments. The set must contain positive integer keys with true values. These IDs identify enchantments, not spells or auras. The core checks equipped weapons through GetInventoryItemID and C_Item.GetItemInfoInstant. It reads each weapon's enchantments through C_Item.GetWeaponEnchantInfo. A matching entry must have hasEnchant set. Empty slots, non-weapons, and unknown item data do not activate the condition. Later refreshes retry unknown item data. The core checks both hands on the regular refresh interval. It does not read unit auras for this mechanic. Set invert on a tanking condition to require that the player does not tank the living hostile target. A target without threat data satisfies this inverted condition. Set grouped on a tanking condition to require a party or raid. This modifier applies with or without invert.

Aura filters support HELPFUL, HARMFUL, HELPFUL|PLAYER, and HARMFUL|PLAYER. A raw aura condition must pair the PLAYER filter with ownAura = true. A false or absent ownAura flag keeps every caster. Dispel conditions require HARMFUL and a declared dispelType. Set invert on a dispel-type condition to highlight when the selected unit has no matching debuff. An inverted dispel condition requires the highlight visual. The client moves the highlight outside the viewport while a matching debuff is active. This uses the same secure layout path as glow suppression. Addon Lua does not read aura presence.

Set suppressGlow on a plain aura rule to reference a non-aura glow rule. The glow selector must cover every action that the aura rule selects. Rule order does not affect this dependency. Each suppressed visual uses a separate secure aura group with one layout element. The client moves the glow outside the viewport while a matching aura is active. An empty or disabled group contributes no displacement. The core chains group anchors for multiple suppressors. Addon Lua does not read aura-owned objects or secure layout geometry. The suppression follows aura presence, not an application count. Public size anchors resize aura-driven glows without calls on aura-owned frames.

The visuals are highlight, red-blink, and glow. A suppressor or a number-only combo-points rule can use none to omit its visible feedback. Every glow has a separate cooldown frame, including aura-driven glows and glows that bypass usability. The core calls C_ActionBar.GetActionCooldownDuration with ignoreGCD and passes its active result to SetAlphaFromBoolean. Cooldown changes do not disable secure aura slots or change their filters. The core calls C_Item.GetItemCount without the bank and with item charges. A consumable glow also requires a positive count. Other item classes do not use the bag count. The count gates every glow on the action. Highlights and red warnings ignore the count. Item macros do not use the count, because Prism cannot identify their item. An uncached item has no class, so the count cannot gate its glow until the client caches it. Exhausted items do not disable secure aura slots or change their filters. The core keeps condition alpha separate from animation alpha. Separate frames combine secret conditions without a Lua comparison. Aura slots remain under client control. Overlay frames use the action button's strata and a frame level directly above the button. The overlay follows GetEffectiveAlpha from the action button. Aura containers are children of the overlay. Aura suppression containers use UIParent, because they only contribute a layout anchor.

Rule helpers

Use local Rules = Prism.Rules in a declaration file.

Helper	Result
Rules.TargetDebuff(auraSpellIDs, options)	Returns a target debuff condition.
Rules.UsableGlow(key, spellIDs)	Returns a complete usable-action glow rule.
Rules.Union(...)	Returns the union of ID sets without changes to the input sets.
Rules.RankedAura(key, ranks, options)	Returns a complete aura rule with the same and stronger aura ranks for each declared action.

RankedAura requires unit and a base filter of HELPFUL or HARMFUL. List the ranks from weakest to strongest. A numeric rank uses the same ID for its action and aura. A structured rank has a spellID and an auraSpellIDs set for distinct or additional aura IDs. Related aura IDs do not become action selectors. The helper does not change the rank list or the options. The helper includes the action ID only when every declared action also identifies its aura. The optional fields are ownAura, applications, visual, requireUsable, and suppressGlow. ownAura adds the PLAYER filter and the caster check. applications selects aura-stacks. The default visual is highlight. A suppressor can use visual = "none" with suppressGlow.

For example, a declared buff family can use this rule:

Rules.RankedAura("ranked-buff", buffRanks, {
    unit = "heal-target",
    filter = "HELPFUL",
})

TargetDebuff supports ownAura, includeActionSpellID, and applications options. It derives both caster checks from ownAura. It selects aura-stacks when applications is set. It does not infer aura IDs from action IDs or rank-filter its declared aura IDs.

For example, an own target debuff can use this declaration:

{
    key = "own-debuff",
    action = { spellIDs = actionSpellIDs },
    condition = Rules.TargetDebuff(auraSpellIDs, { ownAura = true }),
    visual = "highlight",
}

Use explicit rule tables for other combinations. Do not add a helper for each concrete spell.

Prism.Start calls Rules.Prepare before it creates the controller or action overlays. The validator checks keys, fields, selectors, mechanics, visuals, units, ID sets, caster checks, and glow dependencies. It returns the rules in dependency order without changes to the declarations.

Validation

The client runs Lua 5.1. Use Lua 5.1 for the syntax checks and tests. Later Lua versions remove unpack and compute % differently, so some tests fail.

mise.toml pins Lua 5.1.5. Run mise install once to install it. mise provides it as lua and luac.

luac -p Rules.lua Core.lua Shared.lua Prism.lua Classes/*.lua tests/*.lua tests/PrismTest/PrismTest.lua
lua tests/rules.lua
lua tests/mechanics.lua
lua tests/composition.lua
lua tests/runtime.lua
lua tests/probe.lua
bash -n install.sh
bash -n tests/install.sh
bash tests/install.sh

CI installs the Ubuntu lua5.1 package. That package names the commands lua5.1 and luac5.1.

Test file	Coverage
tests/rules.lua	Tests helpers and validators with synthetic IDs, then validates and selects every declared class through the TOC.
tests/mechanics.lua	Tests health thresholds, resources, combo points, numeric overlays, cooldowns, threat, groups, selectors, and filters. Also tests item spells, item macros, item counts, weapon enchantments, delayed data, and unit changes. All tests use synthetic IDs.
tests/composition.lua	Tests independent visuals, combo-point limits, finisher glows, numeric overlays, health, ranked aura glows, cleansing, usability, pet combat, and secure aura suppression. All tests use synthetic IDs.
tests/runtime.lua	Tests visuals, frame layers, animation, button opacity, events, refresh intervals, bar discovery, placement, reuse, and security guards.
tests/probe.lua	Tests the standalone test addon, combat steps, report persistence, and controls.

Keep behavior tests at the mechanic level with synthetic IDs and rule declarations. A spell that uses tested mechanics needs no new behavior test. Extend an existing mechanic or helper test for missing coverage. Do not add scenarios for behavior that existing tests cover. The generic rule tests validate each class loaded through the TOC. They do not duplicate production spell lists or class support policies. Do not keep class-specific, spell-specific, or racial-specific automated behavior tests in the repository. Use a temporary test outside the repository to reproduce a declaration-only bug, then remove it after validation. Keep a persistent regression test only when it adds missing mechanic or helper coverage with synthetic data.

The mock does not reproduce aura selection, texture rendering, or client security restrictions. Configuration validation cannot prove that a spell ID or mechanic expresses the intended behavior. Verify spell IDs against client data and test the affected behavior in the client.

Client checks

Use Prism Test for the isolated secure layout experiment. Install it with bash tests/install-probe.sh.

Before release, verify the declared spell IDs in version-matched SpellName and SpellEffect data. Verify rank order against Spell.NameSubtext_lang and class membership against SkillLineAbility. This verification must use the exact Forever client build.

Run ./install.sh to install every source file listed in the TOC. Set PRISM_ADDON_DIRECTORY to install in another directory. Use /reload, then run every applicable client check in and out of combat. The checks must produce no Lua error or blocked-action error. Every glow check requires a ready action cooldown. The global cooldown does not hide a glow.

Feature	Check	Expected result
Druid buff highlights	Test the declared targetable Druid buffs on the player and another assistable target. Apply and remove equal and stronger ranks.	Each declared targetable buff follows the heal target. Only the selected unit's equal or stronger rank activates the highlight.
Druid player-only buffs	Apply and remove Dash, Enrage, Nature's Grasp, and Prowl on the player. Test every declared rank. Trigger Nature's Grasp against an enemy. Change targets and action usability.	Only the matching player buff activates each highlight. Equal or stronger Dash, Nature's Grasp, and Prowl ranks count. The triggered root does not keep the Nature's Grasp highlight active.
Rogue player buffs	Apply and remove Stealth, Sprint, and Evasion. Test every rank. Change targets and action usability.	Each highlight follows only an equal or stronger matching player buff. Target selection and usability do not affect it.
Vanish stealth highlight	Test both Vanish ranks before, during, and after normal Stealth and improved stealth. Let improved stealth expire without leaving Stealth. Change Stealth ranks, targets, usability, cooldowns, action pages, and button placement.	Vanish highlights throughout normal Stealth and improved stealth. It stops after stealth ends. Target selection, action usability, and cooldowns do not affect the highlight.
Vanish low-health glow	Test both Vanish ranks above, at, and below 20% health. Change maximum health, targets, usability, and stealth. Test death, combat, fall damage outside combat, action pages, and button placement.	Vanish glows only in combat while the player is alive, the action is usable, and health is at most 20%. Fall damage outside combat does not activate the glow. The glow does not change the stealth highlight.
Shank energy glow	Test both ranks at their energy limits and one point above. Test every Flash of Steel rank, current cost changes, maximum energy changes, and talent changes. Test combat, death, usability, cooldowns, macros, action pages, and button placement.	Shank glows only in combat while usable if the full energy gain fits after its current cost. With 100 maximum energy, a 5-energy cost, and no talent bonus, the limits are 90 and 80 energy. Each Flash of Steel point lowers the limit by 3 energy. Combat exit hides the glow.
Glow cooldowns	Test spell glows, item glows, macros, aura-driven glows, and Anti-Venom during their action cooldowns. Test the global cooldown separately. Apply matching highlights and red warnings.	An action cooldown hides every glow until ready. The global cooldown does not hide glows. Highlights and red warnings keep their separate conditions.
Item availability	Exhaust each cleansing and poison item. Change the carried count between zero and one. Test in and out of combat. Change action pages and button placement.	A consumable glow requires a carried use. Every glow on the action follows the count. Highlights and red warnings do not use the count.
Rogue finishers	Test every action rank. Build and spend zero through five combo points. Apply weaker, equal, and stronger Slice and Dice buffs and Expose Armor debuffs. Use Expose Armor debuffs from different rogues. Apply and remove Rupture bleeds from the player and another rogue. Change targets and action usability.	Usable Eviscerate glows at five points. Five combo points alone do not make Slice and Dice, Expose Armor, Rupture, or Kidney Shot glow. Slice and Dice highlights for an equal or stronger buff. Expose Armor highlights for an equal or stronger target debuff from any caster. Rupture highlights only for the player's equal or stronger bleed. The buff and debuff highlights do not require a usable action.
Combo-point numbers	Build and spend points on each declared finisher. Change targets, usability, spell cooldowns, and the global cooldown. Apply and remove the matching buffs and debuffs. Change button size, UI scale, action pages, and spell placement.	The green number appears only with positive points, a usable action, no spell cooldown, and no matching aura highlight. The global cooldown does not hide the number. The outlined number follows the button size. Hidden bars and replaced actions leave no number.
Rogue control highlights	Test Cheap Shot, Blind, and every Kidney Shot, Gouge, and Sap action rank. Apply and remove matching debuffs from different rogues. Test weaker and stronger Kidney Shot, Gouge, and Sap ranks. Change targets and usability.	Each action highlights for its matching target debuff from any caster, regardless of usability. Both Kidney Shot ranks accept either stun rank. Gouge and Sap also accept stronger ranks. A weaker Gouge or Sap rank does not activate the highlight.
Riposte feedback	Test Riposte before and after a parry, then let the activation window expire. Change energy and cooldowns. Apply and remove Riposte's disarm from different rogues. Change targets, macros, action pages, and button placement.	Riposte glows only while usable with a ready action cooldown. The global cooldown does not hide the glow. The disarm highlight accepts any caster, regardless of usability or cooldowns. Neither visual requires the other.
Rogue talent proc	Test every Sinister Strike and Backstab rank. Test each rank of Remorseless Attacks. Trigger and consume Remorseless. Change combo points from zero through five. Switch targets and change usability.	Sinister Strike and Backstab glow only while usable with Remorseless below five points. Five points suppress both glows.
Instant Poison glow	Test every Instant Poison item rank. Place a macro with an Instant Poison item tooltip on the bar. Test bare #showtooltip. Change the tooltip item. Apply different poisons to each weapon. Remove or exhaust one poison. Swap weapons, remove the off-hand weapon, and equip a shield. Test permanent enchants, non-poison coatings, usability, combat, action pages, and button placement.	Each usable item with a carried use glows if either equipped melee weapon has no poison. Item macros match the application spell. Prism does not treat raw macro IDs as item IDs. Any poison rank counts. Empty slots and non-weapons do not require poison. Permanent enchants and non-poison coatings do not count. Crafting spells receive no poison reminder.
Rogue quiet actions	Use Pick Pocket and Throw with and without Stealth. Test an undeclared Rogue ability.	These actions receive no Rogue-specific highlight or glow. Shared item and racial rules remain unchanged.
Racial buffs	Apply and remove each supported racial on characters from different classes. Change target selection and action usability.	Each action highlights only for its own active buff on the player. Other targets and racial buffs do not activate it.
Item buffs	Apply and remove a buff whose aura ID matches the item use spell ID. Test Night Watchman's Torch. Change targets and action usability. Test an item without a use spell. Change action pages and item placement.	Only the matching player buff activates the item highlight. Other aura IDs and spell actions do not activate it. Target selection and usability do not affect it.
Druid self buffs	Apply and remove weaker, equal, and stronger Mark and Thorns ranks from different casters. Select the player, another assistable target, an enemy, or no target. Change action usability. Test flight and player death.	Each usable spell glows when the player lacks an equal or stronger buff and is the heal target. A weaker buff activates the glow. An unusable spell does not glow.
Explicit buff scope	Test undeclared Druid spells and buffs on Warrior, Hunter, and unsupported classes.	No automatic buff highlight appears. Existing explicit mechanics continue.
Druid healing	Test all three spells at full and partial health on the player and an assistable target. Test death, hostile targets, and no target. Apply and remove Regrowth and Rejuvenation. Change action usability.	The full-health highlight requires a living heal target at full health. Buff highlights remain independent. Action usability does not affect either highlight.
Own target debuffs	Compare the player's Rend, Serpent Sting, Garrote, Rupture, Moonfire, Rip, or Rake with another caster's copy. Test every declared rank. Change action usability and targets.	Only the player's aura activates the highlight. Druid debuffs, Garrote, and Rupture require an equal or stronger rank. Other rules match their declared IDs.

Test Bash, Demoralizing Roar, Faerie Fire, Hibernate, and Soothe Animal from different druids. Test every declared rank. Change action usability and targets. Test the other declared shared debuffs.	Druid highlights and Rogue shared debuffs accept equal or stronger ranks from any caster. Warrior and Hunter rules match their declared IDs. Usability does not affect these highlights.
Sting replacement warning	Apply each sting from the player and another hunter. Change the action usability and target.	Only the player's different sting activates the red warning on a usable action. The matching sting and another hunter's stings do not activate it.
Aura stacks	Change Sunder Armor from four stacks to five stacks, then back to four stacks.	The highlight appears only at five stacks.
Fear warning	Apply and remove Rend or Deep Wound from different casters. Change Intimidating Shout usability and target hostility.	The warning blinks red only with a matching hostile target debuff and a usable action.
Dispel feedback	Test poison, disease, and curses on the player and an assistable target. Remove the debuff or make the action unusable. Check Anti-Venom when the client reports it as unusable.	Usable bandages blink for poison. Anti-Venom glows for poison while a carried use remains, regardless of usability. Other cleansing actions glow only while usable with their matching debuff. Cleansing actions highlight without a matching debuff, regardless of usability.
Druid cleansing	Test Remove Curse with curses and Abolish Poison with poison on the player and another assistable target. Apply and remove the Abolish Poison buff separately from the poison debuff. Change action usability and targets.	Each usable spell glows only for its matching debuff on the heal target. Each spell highlights without that debuff, regardless of usability. The Abolish Poison buff keeps its independent highlight.

Energy feedback	Test Shifting Power at 60, 61, 70, 99, and 100 energy with a 100-energy maximum. Change action usability, Druid forms, and maximum energy. Test player death.	At a 100-energy maximum, a usable action blinks red from 61 to 99 energy. Full energy activates only the normal highlight, regardless of usability. At 60 energy or less, neither visual appears. Player death hides both visuals.
Rip glow	Build and spend combo points on an enemy. Change targets and action usability. Apply and remove weaker, equal, and stronger Rip ranks from the player and another druid. Test every declared rank.	A usable Rip glows at exactly five points only without the player's equal or stronger bleed. Another druid's bleed does not suppress the glow.

Growl glow	Gain and lose target threat while solo, in a party, and in a raid. Select an idle enemy without threat data. Change action usability. Test a friendly target, a dead target, and no target.	A usable Growl glows only while grouped and not tanking a living hostile target. No threat data also permits the glow. The tanking highlight remains independent of usability.
Faerie Fire glow	Apply and remove weaker, equal, and stronger ranks from different casters. Change action usability and targets. Test a friendly target, a dead target, and no target.	A usable action glows only for a living hostile target without an equal or stronger debuff from any caster. A weaker rank permits the glow.

Select a friendly target, a dead target, or no target.	Each spell glows only while the action is usable and the player tanks a living hostile target. Feint also requires a party or raid.
Placement	Test every supported bar. Change UI scale, button size, bar visibility, action pages, and spell placement. Open bag windows over buttons with active visuals.	Each visual stays aligned with its button and below bag windows that cover the button. Hidden bars and replaced actions leave no stale visual. A faded bar also fades its visual.
