Replaces the icon of bolstering so the guy in the icon is dabbing on you
If you bolster the heck out of a mob there will be a bunch of dudes dabbing on you and you will have a bad time
If you get tired of being dabbed upon then just delete the file located at: "\World of Warcraft\Interface\Icons\ability_socererking_arcanefortification.tga" or you can just get good and stop bolstering mobs. Up to you.
