  • Bravura Presence: "When an ally who can see you spends an action point to take an extra action and uses the action to make an attack, the ally can choose to take advantage of this feature before the attack roll. If the ally chooses to do so and the attack hits, the ally can either make a basic attack or take a move action after the attack as a free action. If the attack misses, the ally grants combat advantage to all enemies until the end of his or her next turn."[MP:103]
