I’m not sure what’s going on when I use the mad king costume. I’ve tried the tonics, and they all work fine, letting me brawl to my heart’s content. However when I use mad king thorn (the gem store costume) I can use any of his abilities, except his “1” attack. It kicks me out of costume brawl (puts my number 5 on cooldown) the second I use it.
It basically means I can’t participate in costume brawl if I want to use my auto attack.
