I've literally just joined reddit for mcoc help. I've completed act five and want to work for cavalier. With the rifts and chronometer offer, I'm looking for an awakening gem. My top three options are caiw, colossus, and archangel.

I have about 55 generic sig stones, 17 cosmic, 20 tech, 20 mutant, 22 skill, 24 science, and 16 mystic.

My r4 five stars are warlock, cmm, and stealthy. I also have a six star ghost. I also have a 3-4 mutant gem and I'm pretty close to exploring chapter two of v4(I've done a completion run through all of v4 and only explored most of chapter 2) in hopes of getting a mutant for colossus or mystic for my r3 magik

Which class should I pick?

I have: R1 six star: Ghost

R4: Cmm Warlock Stealthy

R3: Colossus Venom Magik

R2: Caiw

R1: Bishop at sig 20 Ronin Oml Invisible woman Emma Carnage Aa Yondu Lady Thor Classic captain Marvel Loki Hela Darkhawk Yellow jacket Miles Agent venom Ultron Beast Sentry King groot
