i dunno about everyone else but if i'm inside his ice sleet storm it dc's me without fail... the 1st time it took at least 8-10 client resets
thankfully his dps is somewhat poor so i never died during those resets... but his regen was quite significant... it didn't help that the only way i could kill him was to avoid stepping into his storm...
after all those resets i ran out of sp using conventional tactics and ended up having to 1hd him down with wounding...
