What I did was:
General Raze wish to heal himself... I didn't remember exactly, but I pull one of the 2 levers (or both?) and run IN the left healingpart! I stay IN and fight for my life (used immediately potions) ... and since Raze wish to heal himself, but I stand IN his way, Raze must first try to kill me before he can heal himself! On that way I can kill him very fast, but his compagnons are maybe a problem to defeat, I know wink

I wish you all the luck !!
