Just got his 6 star soul. I decided to do chainbreaker. I have him in 4 piece stoneskin / savage. I also built him for both forms. Stats at bottom - 102k hp in alt form. (no relic on atm). 

Curious if people have tested and think I should full send on his alternate form - meaning sacrifice Atk for HP / Crit Dmg. He's definitely decent but feels like I could get into a face off with a strong enough healer and not be able to finish it. He just doesn't nuke the way I wish a 6 star mythic would.

Three questions:

1) Should i sacrifice the stoneskin for more damage? Approximately 15% - 22% more.

2) What are thoughts on chainbreaker? His weakness is clearly CC. Any recs?

2) In terms of relics, Cat's Gaze is useless on him. I'm between Gorecrescent and Malefic Talon. Maybe even Demonic Effigy. Thoughts?
