Arcane Weapon Bond — Speed

The magus can add the speed property to a weapon enhanced with his arcane pool, but this consumes 3 points of enhancement bonus granted to this weapon. When making a full attack, the wielder of a speed weapon may make one extra attack with it. The attack uses the wielder's full base attack bonus, plus any modifiers appropriate to the situation. (This benefit is not cumulative with similar effects, such as a haste spell.)
