Provides detailed, meaningful and customizable information about items to make comparison easier.
CategoryBags & Inventory

What it doesEdit

RatingBuster started out as an addon that converts combat ratings in your tooltips into percentages, so that you have more meaningful information when comparing different items.

The design aim of RatingBuster is to provide detailed, meaningful and customizable information about items so you can easily decide for yourself which item is better.


Read the documentation found here. This includes the feature list, supported addons, slash commands, an explanation of all the math, and the version history.

Documentation can also be found in other languages:

RatingBuster would like to support Traditional Chinese (Taiwan), Spanish, French, and Korean, but help is needed. If you can help, please send translation or localization files and they will be included in the next release.


You can leave comments about RatingBuster on WowAce, Curse, and WoW Interface.

Where to get itEdit


  • Supports talents, buffs and racials that modify your stats for all classes
  • Fully customizable, decide what you need to see and what you don't want.

Rating ConversionEdit

  • Converts combat ratings into percentages.

Stat BreakdownEdit

  • Breakdown Strength, Agility, Stamina, Intellect and Spirit into base stats.
  • Supports talents, buffs and racials that give you extra bonuses.
Ex talent: Lunar Guidance - "Increases your spell damage and healing by 8%/16%/25% of your total Intellect."
Ex talent: Heart of the Wild - "Increases your Intellect by 4%/8%/12%/16%/20%. In addition, ......etc"
Ex: +13 Intellect (+234 Mana, +0.18% Spell Crit, +3.9 Dmg)

Stat SummaryEdit

  • Summarizes all the stats from the item itself, enchants and gems, converts them to base stats and displays the total value and/or difference from your current equipped item.
Ex: Crit Chance - Adds up agility and crit rating from the item, enchant and gem. Converts agility and crit rating to crit chance, and displays the total in a single value.

Item Level and Item IDEdit

  • Item Level is obtained from the WoW API, not a calculated value.
  • Item ID is useful for advanced users.

Auto fill gems in empty socketsEdit

  1. You can set the default gems for each type of empty socket using "/rb sum gem <red|yellow|blue|meta> <ItemID|Link>" or using the options window.
  2. To specify the gem of your choice, you will need to give RatingBuster the ItemLink or the ItemID of the gem.
  3. ItemLink example: type "/rb sum gem blue " (last char is a space) and link the gem (from your bags, AH, ItemSync or whatever), then press <enter>.
  4. What if you can't link the gem? Well thats what ItemID is for. Find your gem on and look at the URL, for example "", 32193 is the ItemID for that gem. Go back in wow, type "/rb sum gem red 32193" and press <enter>.
Note1: If you have "/rb sum ignore gem" on, the auto fill gems won't work.
Note2: Meta gem conditions and SetBonuses work, so if you don't meet the conditions, StatSummary won't count them.
Note3: RatingBuster will only auto fill empty sockets, if the item already has some gems on it, it will remain.
Note4: Empty sockets filled by RatingBuster will keep the "Empty Socket Icon" so you can still easily tell what color socket it is.
Note5: Gem text filled by RatingBuster will be shown in gray color to differentiate from real gems.
