these heal themselves.. cast Fungal Growth. Had the mob down to 6%.. i'm oom.. using a clickie dot (swarming death) and he was healing faster than I could nuke/med and also cast dot.. after like 10 mins.. he was at 48% health.. I'm still at 5% mana.. so evac'd.. waited 4 mins . .and went and got revenge in about 1 min LOL
sick regen or something, i kited him to 50% then i couldnt get him any lower, maybe he was healing. he had some sporali junk he was casting but i didnt see any effects
