My friends are playing Barrel Roll is a Fee Action, since there is no Token to represent this maneuver. Can anyone help with this one?

See page 8. It clearly identifies a barrel roll as an action, of which, you only get one of per activation.

There's no token because there's nothing delayed about it - you don't need to remember to do a Barrel Roll later, you just do it.

It's not a free action.

Thanks guys, that's what I thought.
