Drain Vitality

Shadow Hand (Strike)
Level: Swordsage 2
Initiation Action: 1 Standard Action
Range: Melee Attack

Saving Throw: Fort partial.

A faint nimbus of sickly grey shadow surrounds your weapon. When you attack, this shadowy aura flows into the wound you inflict, sapping your opponent's strength, vitality, and energy.

Make a single melee attack. If you successfully hit the creature, and he fails a Reflex save against 12 + your Wisdom modifier, he takes two points of Constitution damage.
