Bloodletting Strike

(Tome of Battle: The Book of Nine Swords, page 75, DnD 3.5)

Shadow Hand (Strike)

Level: ; Swordsage 5
Prerequisite: Two Shadow Hand maneuvers
Casting Time: 1 standard action
Range: Melee attack
Target: One creature
Saving Throw: Fortitude partial

Spinning your blade in a butterflylike pattern, you administer a dozen precise cuts in an eyeblink. Blood flows from your foe’s opened veins.

As part of this maneuver, you make a single melee attack. If this attack hits, your opponent takes 4 points of Constitution damage in addition to your attack’s normal damage. A successful Fortitude save (DC 15 + your Wis modifier) reduces this Constitution damage to 2 points, although the foe still takes full normal melee damage.
