To make this bug work what you need it
1. Flask of Petrification
2. The warrior talent Second wind
Beat the crap out of your target as per normal, and as you start to lose and get close to dieing, pop the flask and watch as second wind recovers most of your hp
This works best on fun servers, and prot geared warriors ( for the extra HP so you get more Bang for that 4% or what not)
