What is tiLevel?
tiLevel is an abbreviation for "true item level" and is a light weight mod that calculates how close an item is to its item level budget by displays a percentage in the tooltip. Each of the stats are weighted with consideration to the item's rarity. This fun mod let's players see how close (or far) away an item is to it's budget.
Note: The mod uses a reversed engineered formula to calculate the true item level and is not official Blizzard calculations. This means that if a item is way above or way below the assigned item level, don't storm Blizzard's walls!
tiLevel in Action

If you wish, you can see the manual calculation of an item by using the command:
/tilevel <item link>
/til <itemlink>
This will show the weight of each stat and how tiLevel calculates each individual stat.
Exceptions
While tiLevel will calculate most items, it cannot calculate all. For example, there is no known formula to manually calculate the true item level of trinkets. Trinkets generally have random procs that make it very difficult to break down into a mathematical formula. Also, items that do not have stats will be unable to be calculated as well. This includes low level, bows, crossbows, wands, etc. The true item level is determined by weighing stats. If there are no stats, the true item level will not be able to be calculated.

Installation Guide
- Exit "World of Warcraft" completely
- Download the mod you want to install
- Make a folder on your desktop called "My Mods"
- Save the .zip/.rar files to this folder.
- If, when you try to download the file, it automatically "opens" it... you need to RIGHT click on the link and "save as..." or "Save Target As".
- Extract the file - commonly known as 'unzipping'
Do this ONE FILE AT A TIME!
- Windows
- Windows XP has a built in ZIP extractor. Double click on the file to open it, inside should be the file or folders needed. Copy these outside to the "My Mods" folder.
- WinRAR: Right click the file, select "Extract Here"
- WinZip: You MUST make sure the option to "Use Folder Names" is CHECKED or it will just extract the files and not make the proper folders how the Authors designed
- Mac Users
- StuffitExpander: Double click the archive to extract it to a folder in the current directory.
- Verify your WoW Installation Path
That is where you are running WoW from and THAT is where you need to install your mods.
- Move to the Addon folder
- Open your World of Warcraft folder. (default is C:\Program Files\World of Warcraft\)
- Go into the "Interface" folder.
- Go into the "AddOns" folder.
- In a new window, open the "My Mods" folder.
- The "My Mods" folder should have the "Addonname" folder in it.
- Move the "Addonname" folder into the "AddOns" folder
- Start World of Warcraft
- Make sure AddOns are installed
- Log in
- At the Character Select screen, look in lower left corner for the "addons" button.
- If button is there: make sure all the mods you installed are listed and make sure "load out of date addons" is checked.
- If the button is NOT there: means you did not install the addons properly. Look at the above screenshots. Try repeating the steps or getting someone who knows more about computers than you do to help.
Translations
When you download a mod, please be sure that the mod is compatible with your translation of wow. Some mods only work on the US versions, while some only work on some of the various European versions. These variations are called "Localizations".
TOC Numbers (Out of Date Mods)
When Blizzard patches WoW, they change the Interface number. This means that all mods will be "out of date" unless or until the author releases a new version for that interface. Some people go into the .toc files and update the numbers themselves, but this is STRONGLY advised against as it will cause problems locating possible incompatibilities addons. When you log into WoW after a patch, you DO NOT have to delete your interface directory. All you have to do is simply tell WoW to ignore the interface numbers and load all the mods anyway. All you have to do is, while at the "character select" screen, look in the lower left corner and click on the "addons" button. A window will pop up listing all your installed mods.
If you look in the upper left corner of that window there should be a box that says "Load Out of Date AddOns". You want to CHECK this box. Now simply go into WoW normally and all your mods should load. As of the 1.9 patch, you will have to do this after EVERY patch/update that Blizzard posts! If you encounter any problems with a mod after a patch, please be sure to let the author of the mod know so they can fix it.
