I have seen this skill in several builds and I have tried it repeatedly without much success. The damage advertised sounds good, but the problem appears to be that the AOE is fairly small... it doesn't seem to reach as far as my wand for example, and two, the spirit is usually still standing after the fight is over. It's like all the mobs are dead, now lets all go stand around destruction and watch him blow up :/ (I had him in slot 1 so he was always the first cast)
I'm guessing that he is really more applicable to large crowd control or mobs that take awhile to kill, and not a skill that you would load as your standard rt template... otherwise this skill seems like wasting a skill slot. Am I correct or am I not using him properly ? tia

Is there a quick way to target destruction or do you just keep him out of the spirit clump so he's easy to find ?
