Strongest heavy attack ever??

Cain

Anyone able to beat the strength of this heavy attack? R5 5* Domino with trinity and the perfect 2 nodes to help her in dungeons resulted in this heavy attack that would’ve hit for 149,225 damage had the opponent had enough health. (Math is including what the incinerate damage would be)

(2.5)(6,365+53,337)

Has anyone got that beat??
