1. What is it?
This addon adds an extra pair of stats to the character screen that show the approximate mitigation percentage you currently have. After extensive testing, the new formula appears to be exact for lower-level characters. I still need confirmation it's working for Veteran Ranks.

An options screen is included. You can select to cap the displayed value at 50%, and/or display anything over 50% as a separate percentage. Even though your rating can go arbitrarily high, you'll never get more than a 50% damage reduction, so values over that amount could be misleading.

The addon works with SoftCapInfo and Harven's Extended Stats, but I haven't tested any other addons. It currently doesn't have localization support -- it's only in English. If anyone wants to give me translated strings, I'll learn how to put them in the addon.

For more detail, my formula is:

percentDisplay = (displayRating - 100) / currentLevel

Where currentLevel is 50 for VR1, 51 for VR2, 61 for VR12, etc.

Anything under 0% gets set to 0%, since the game doesn't allow negative damage reduction.

2. How do I install it?
The best way is probably to install Minion from http://minion.mmoui.com. From there, you can search for MitigationValue under the "Find More" tab, then click the "Install" button. Minion will tell you if any addons have been updated, and allow you to install the update. There's even an option to automagically install updates when you run the program.

The other way is to install manually. There is a tutorial at http://www.esoui.com/forums/faq.php?..._howto_install, or you can read my instructions in the included ReadMe.rtf file after downloading (note that you can open the file with any text reader -- the extension is just because .txt files don't play nicely with ESO).

If you install while logged in, type /reloadui <press enter>, then if it doesn't show up, press Escape to open the main menu, click Add-Ons, check "Allow out of date add-ons" if mine is red, check the checkbox next to my addon, click "Reload UI".

3. Change Log
1.04 - Added code that should have been in 1.03 to prevent armor value from dropping below 0%.
- Added code to assume level 50 stats when battle leveling is in play.
1.03 - Updated to a new, improved formula that works better for very low levels and very low armor ratings.
- Updated the font style on my control to match the stock stats controls for those using font replacers.
1.02 - Added an options menu to choose different display methods.
1.01 - The control caps values over 50%, because the game has a 50% hard-cap in damage reduction. So if you have enough rating for 52%, it will display 50%.
1.00 - Release version.

5. Copyright
I'm pretty certain there's a giant bit of legalese we all agreed to that says every addon made for ESO belongs to Zenimax, so as long as they don't care this code is more-or-less public domain.

However, if that legalese somehow doesn't actually apply, or I'm just retarded and can't read, or whatever, here's some stuff I copied out of another guy's addon that looks like it fits the bill (TL;DR: do whatever, just give me credit if you copy my code):
