That's exactly the kind of of useful info I was hoping for, thank you man.
Yeah, right now Wormwood is still sufficient (GR50) and allows me not to use locust swarm and have another skill in it's place instead. I noticed the slow lately but it's not really written anywhere in the haunt's skill descripiton, that's why I was concerned.
Indeed - if every haunted enemy is slowed, BotT seems a great idea. I'd still use Pain Enhancer (DoT) too, but what about the third one? I was thinking about keeping the TotS, but I don't know if it's worth it, but the rest is either deffensive - which I don't really need, or useless for the build. Or maybe BotP?
