Exploding in a bloody cloud sounds, uhmm, nice, I always wanted to live the masochistic dream.
Maybe you can upgrade the talent, so that your bowels, flying around, entangle and immobilize additional foes.
Would it really work together with Comeback Kid? Does that talent let you die and revives or just survive the mortal wound? In the latter case exploding from Unstable would not be reasonable.
Unstable and Morning Person will go together for sure. But actually I hate it if I have dead party members in a fight.
