Well, if you use Biological class: Get Disrupt on lvl 2, place it on your bar 4 times, and get Stun, place it there too. And then just put Veradux on Phalanx, and Roald on Relenteless. Use Disrupt every turn on the coackroach, so he can't use his health buff. So easy.
With Hydraulic: Simply use Flash Freeze and Mind freeze, and he will go down easily.
I am biological. I've tried to use the disrupt method, but it always gets to go first when I fight it. So it always does that 700-900 heal thing. So, what should I do?
well be able to deal about 1000-1200 then after the roach virtability buffer died out knock it out and use your strongest moves before it gets back up thats if your doing heroic mode
