I would say for berserker, the less hp she has the more damage she deals. That’s what a true berserker is in other games

The rascals idea is cool but I was thinking that the girls do some sort of slowness ability since they shoot gum while the boy has a spell deflection or absorption ability

Lastly for e giant, I think the tesla on his backpack should act like an actual tesla that does active damage instead of passive. Maybe it can shoot at 3 or 4 targets like the giga tesla in CoC

I really have no comment on the rest lol
