I really have no idea how you're supposed to fight a guy who drains 3 AP and does 12k damage every turn. Not even Iceman can stun him without getting crazy-lucky on the first turn or two before he just melts to that passive damage.
Which reminds me, why does his passive do so GD much damage!? The text makes it sound like it should be 1-3k, not 12k, which is what I keep getting hit for.
You need to fix him, by which I mean make it possible to play even one single character in your cast of thousands that can beat him reliably.
