Vesper Primer+Immediate Actions+Three-Sword Style

Sphere: Dual Wielding

Prerequisites: Dual Wielding sphere, base attack bonus +6.

You gain the ability to wield a sword in your teeth, treating your mouth as an additional hand that can only be used to wield a one-handed or light weapon. While wielding a weapon in this manner, you suffer a 50% spell failure chance to cast any spell with a verbal component, or increase any existing spell failure chance for spells with verbal components by 50%. In addition, whenever you make a dual attack, you may make an additional off-hand attack with the weapon wielded in your mouth as an immediate action.
