This is one rather annoying little cockroach, ive been trying for the past day to beat him, using various strategys, and his regenerative powers always end up making it damn near impossible. Is there a way to train up levels and become more powerful than him or something? Or is there a strategy that you would suggest to help beat him?
You can look at all the guides. It tells your how to beat him. But i'll save you the trouble... If your biological, equip 3 level 2 disrupts and let your teammates bash him to death. If your psychological, get 2 level 2 tramautize and get a level 2 haunt and use haunt and tramautize (Don't use both tramautizes before the other one runs out, it doesn't stack.) If your hydraulic just keep using regulate on him (doesn't have to be level 3 it could be level 1).
The trick with him is brute force. If you are hydraulic, use imapair, bloodshed, decimate, then wreck. A general tip: If you are fighting multiple enemies, use skills on yourself, but if you are fighting one, using skills on him is more effective.
