@nate38 I know! I got it really late, like with only 2 or 3 fights left. It makes me wonder if the enemy who had it uses it a lot. Because theoretically you could just end up totally f-ed too if they use it every turn.
Funny thing is I still almost lost a fight after getting it because of the rat king guy. I was wasting my turns taking away his dice while he poisoned me but he has a lot of dice so I suddenly realized I was poisoned as F without having really damaged him much, and even though he was down to like 2 dice or something and could barely hurt me anymore, I was so high on poison I only had 2 turns left to survive. BARELY got past him, like literally used my last dice to kill him before his poison would have killed me.
But generally speaking it totally breaks things, boss was a joke. ALTHOUGH, I don't know if it was a bug or not but it just plain didn't work one round. Or maybe she had a dodge going or something? Hmm.
