Clever Positioning

Setting Sun (Strike)
Level: Swordsage 2
Initiation Action: 1 Standard Action
Range: Melee Attack
Target: One Creatures
Saving Throw: Reflex partial.

With a swift flurry of motion, you knock your foe off balance, slip into his space, and force him into the spot you just occupied.

Make a single melee attack. If you successfully hit the creature, and he fails a Reflex save against 12 + your Dexterity modifier, you swap positions with your target.
