I’m making my first fighter and noticed something new (to me). These are two separate attack types. I needed to calculate two attack bonuses for Opportunity Attacks and Combat Challenge attacks because the fighter feats don’t apply to OA’s, just CC. On top of that a recent issue with immediate actions made something else catch my eye.
Opportunity attacks are not Immediate Actions, since they can be take for each creature that provokes them and are not limited to one per round. Combat Challenge is an Immediate action, so therefore it’s not an Opportunity attack? This would mean that a fighter does not add his wisdom bonus Combat Superiority to Combat Challenge attacks.
