I'm sparring with Eitan and my character is too OP to struggle without escaping his bear hug every time. It looks like he has different reaction if you do nothing (talking about you going limp) so I think a good idea for flavor would be fake-struggle. Even if the result is the same for most, for any cases it is different, I would like that ability. It can say "You put up a believable struggle" before continuing to struggleFail or it can just auto-fail.
