Just fought Saru and the guy is pretty OP too.

His activation isn't really high at 57 with 4 turns (since he brings an extra turn) you can probably activate him twice. -15% per activation, ability will remain even if he is dead. That alone is quite a pain. His health is low but level 4 Falkar will need to hit him twice or you need some combo to kill him. That's not really the problem. Death rattle banana bombs basically renders 3 tiles frozen and when it does activate it does considerable damage.

I feel like his ability needs to be take away upon death or he shouldn't have a death rattle.
