If an enemy provokes an attack of opportunity, you can take it, even if you've already taken your allotted number of
attacks of opportunity this round (usually one). You may not make two
attacks of opportunity against the same
target in one round even if using this power, unless the
target provokes two separate attacks.
You can manifest this power instantly, quickly enough to gain an extra
attack of opportunity in the same round. Manifesting the power is a free action, like manifesting a quickened power, and it counts toward the normal limit of one quickened power per round.
