My first question was going to be how you rolled that mist, then I saw that this was an edited character. My next is about your defilers taking so much damage, how/why?
Yes, it's hero edited so that I can test damage vs damage of maximally optimized build variants.
Defilers sometimes take a lot of damage because it's p8 zones that I'm playing in, and often terrorized depending on the content you are watching. They rarely ever die though.
