Flying Tiger

 
Prerequisite(s): Exotic Weapon Proficiency (Hook Sword), Weapon Focus (Hook Sword), Two Weapon Fighting or the ability to treat the hook sword as a special monk weapon, Dex 15+, Base Attack Bonus 1+.
 
Benefit: When taking a full attack action with your hook swords, you can hook the long ends of the weapons together or unhook them as a free action. While the swords are hooked together, they deal only the lower of their two damage dice but they also act as a reach weapon that can be used to attack adjacent foes.
