I hit a roadblock in story mode with Mr. Sinister a while ago because I don't have any of his traditional counters or synergy counters. I was searching through my roster to see if I could find something to beat him and I got to Vox. He's poison immune and has an inherent fury buff in his kit, so I'm wondering If I should put resources on this and r3 him. Can he do that fight? is this safe? anything I should know?
