It
It's only killing Rio. Nobody else. Right when the match starts. Only Rio. When I change to others and take Rio out.. nobody dies.I think those from that enemy that give your unit "CHARMED" status when that enemy die/killed. Which makes your unit fight their friends. And guess what ? Atk multiplier applied here too (but less on def multiplier from the look of it).
If you really don't want anyone die, just boost def and leave atk multiplier alone.
