The barbarian rage power "Come and Get me" States:
While raging, as a free action the barbarian may leave herself open to attack while preparing devastating counterattacks. Enemies gain a +4 bonus on attack and damage rolls against the barbarian until the beginning of her next turn, but every attack against the barbarian provokes an attack of opportunity from her, which is resolved prior to resolving each enemy attack.
Does this power require you to have the Combat Reflexes ability to use more than one attack of opportunity? Or does this override that need?
