DamagePreview

Every spell on your action bar shows how much it will actually hit, heal or shield for – no more guessing, no more spreadsheets.

Features

• Numbers on your action buttons for all spells that deal damage, heal or absorb
• Color-coded at a glance:
  • 🔴 Red – damage
  • 🟢 Green – healing
  • 🟡 Gold – shields and absorbs
• Detailed tooltips with average hit, estimated crit and damage/healing over time
• Works for all classes and every spell rank – the value always matches the rank on the button
• Damage and healing over time shown as the full total, combined with the direct part for hybrid spells
• Adjustable crit multiplier for talents that increase critical damage
• Supported action bars: Blizzard default (including Edit Mode bars), Bartender4, Dominos and ElvUI
• Localized in English, German, French, Spanish, Italian, Portuguese (BR) and Russian

How it works

DamagePreview automatically picks the best available method for your client:

• Clients with combat log access (e.g. Classic Era): DamagePreview measures your real hits. Every talent, buff, debuff and multiplier is included automatically. Crits are tracked separately, and outliers are filtered out. When your spell power changes, stored values are adjusted instantly – no need to re-measure after a gear upgrade.
• Clients with addon restrictions (e.g. WoW: Forever): The combat log is not available to addons there, so values are read from the spell descriptions. DamagePreview detects on its own whether the game already includes your spell power in the description, and adds it itself if not.

Options

Open with /damagepreview or /dpv, or via Options → AddOns → DamagePreview.

• Show numbers on action buttons
• Show details in tooltips
• Estimates from the spell description until the first measurement
• Font size and position (bottom, center, top)
• Crit multiplier (100–300%)
• Reset measurements

Notes

• Measured values reflect your real average against the targets you actually fight, including partial resists.
• For spells with multiple projectiles, such as Arcane Missiles, measured values are shown per projectile.
• Shields cannot crit, so no crit estimate is shown for them.
