Has anyone experimented with his A1 yet? Adds damage equal to 30% of the current shield. Attack also based on HP.

I had a max HP champ (Roshcard) with a shield set on a team and Corpulant Cadaver hit 8k  while at lvl 1 (3stars). 

I imagine that he has potential to be a serious cannon in arena. Give him high HP and speed so he hits before shield depletes. 

Especially with a champ like Roshcard who can cast Block Damage and let Corpulant Cadaver cast another shield on himself for good measure lol.
