each ability once or altogether only one ability?
one question about 2 player game:
If I can use the ability swap skill every round, I will destroy my opponent's game, because his planning can't work anymore
I think this is overpowered, isn't it.
Each ability once. As with items and pets
I'm not sure what you mean by ability swap. Which character and which ability are you refering to? I have a feeling you are misunderstanding something.
