StatSense

Stop guessing whether that item is an upgrade

The default comparison tooltip tells you +10 Agility, -8 Stamina. StatSense tells you what that means for your class and role:

• +10 Agility → +20 ranged Attack Power, +0.19% crit, +0.38% dodge, +20 armor (Hunter)
• +10 Intellect → +150 mana, +0.17% spell crit (Mage), or no benefit if you're a Warrior
• +86 Armor → physical damage reduction 31.69% → 32.41%
• +1% Hit → 5% → 6% of the 9% boss cap
• +40 spell damage → +33 per Frostbolt, +40 per Fireball

…and it ends with a verdict in a unit you already know: Upgrade, +28 Ranged AP equivalent.

Features

Class- and role-aware math

• Strength, Agility, Intellect and Spirit converted with the correct per-class rates (Attack Power per point, Agility per 1% crit, Intellect per 1% spell crit, Spirit mana regen under the 5-second rule).
• Role is detected from your talents (melee, ranged, caster, healer, tank) and can be overridden with /ss role.
• Druid forms: Cat/Bear Attack Power, the Bear Form armor multiplier, and weapon DPS ignored while shapeshifted.
• Weapon DPS and speed, with class-specific advice: daggers for Backstab, slow two-handers for Seal of Command, slow weapons for Windfury.

Things the default tooltip doesn't tell you

• Real armor damage-reduction percentages from your current armor (against level 63 enemies for tanks).
• Hit measured against the melee/ranged (9%) and spell (16%) caps, starting from your current hit.
• Defense progress toward the 440 crit-immunity cap for tanks.
• Spell power shown as damage or healing per cast of your actual spells (Frostbolt, Shadow Bolt, Greater Heal, Holy Light, Lightning Bolt…).
• School damage (+Fire, +Shadow…) checked against the schools you actually cast.
• Resistances, with the raids they matter in.

Set bonuses

• Counts the set pieces you already wear, works out which bonuses a swap would gain or lose, and includes them in the numbers.
• Shows how many more pieces you need for the next bonus.

Accurate, even for uncached items

• Reads stats from both the tooltip and the game's own stat data, so recipes and items you've never seen before still compare correctly.
• Armor kits and other enchant lines are counted.

How to use

• Hover any item. A one-line verdict appears in the tooltip. Hold Alt for the full breakdown.
• /ss opens the compare window. Shift-click an item to compare it with what you're wearing, or shift-click two items to compare them with each other.
• /ss [item] or /ss [item1] [item2] works from chat.

Commands

Notes and limits

• Built for Classic Era / Anniversary (1.15.x), using level-60 conversion values.
• English (enUS) client only for now. Stats are read from the item tooltip text.
• Procs, on-use effects and conditional bonuses ("Attack Power when fighting Undead") are listed but not scored.
• Talents that multiply stats (Blessing of Kings, Heart of the Wild…) aren't applied.
• The verdict uses rough community stat weights. You can tune them in Data.lua.
