If you have psychopath, use Wraith form, put 3 Shock therapy in attack circle, get electrical Storm, Traumatize and then fight. First, use wraith Form, use Shock therapy 3 times in arow then use once more, use electrical storm, then traumatize, then repeat until deafeated. Your Welcome
If you are Biological, equip 4 Disrupts. His Roach vitality costs 8 Focus, so drain his Focus so he won't use it. For a Hydraulic, Mind-Freeze him or stun him. If you are a psychological, use Confinement.
be patient, eventually roald starts using his stuns and silences, just stick with him and chain together for huge stun periods once the roach's buff dies
For hydraulic, get 4/4 ice wall, Subsversion, and protective skills, and 1 hypothermia.
When he uses the annoying Roach vitality, see if he has schadenfreude. If he doesn't, protect yourself for the 4 rounds. Next time when he has both HoT buff, apply ice wall before he casts roach vitality, it lasts 4 turns, so if you cast ice wall before roach vitality, both buffs ends in the same turn. Then, when both buffs has 1 turns left, cast subsversion. It should take around 3200 hp away, after that, quickly attack him with hypothermia, and finish him off. This would work better if he's low on focus, so after taking away 3200 hp, he can't immeadiently cast roach vitality again.
I dont understand how people have trouble with this game, its pretty easy. Best advice I would give is, at the end of each stage play the boss a good some of times gain a lvl, then get his equipment. After that, you should be pretty much set half way through the next stage.
