Description: Your keen and focus and understanding of the Void allows you to attack at blinding speed.

Prerequisites: Base Attack Bonus +10, Void Use, Depths of the Void

You may spend three Void Points as a free action to gain an additional attack at your highest base attack bonus, but each attack (the extra one and all subsequent normal ones) suffers a -2 penalty. You may use this feat multiple times in the same round if you have enough Void points to spend, but all penalties are cumulative. You must gain the extra attacks from this feat before your normal attacks for the round. You must use the full attack action to use this feat.
