Side quests? Nay! Side bosses! Part 2

EDIT: I have to give up on the last one, Satan himself. The fight is too reliant on chance, which was NEVER in my favor since Satan has that insta-kill-everyone attack that players has ZERO ways to counter, mitigate or defend against. Unlike how it was with the Demi Fiend, Satan has NO CLEAR CONDITIONS as to what triggers his insta-win attack, he just does it without warning. I HATE dealing with chance.

Have I told you how much RNG hates me? No?
Well, I'm going to tell you that again.
RNG really hates me.

I try not rely on chance but when fighting Vishnu, the INSANE critical hit rate is something I HAVE to mitigate with skills that decreases that chance.

RNG hates me? The feeling is mutual.
