As a bonus action when you hit a creature with a melee weapon attack with the light or finesse property that deals piercing or slashing damage, you can administer a dozen precise cuts, causing the target to bleed.
At the start of each of its turns while bleeding, the creature must make a Fortitude saving throw.
On a failed save, the target loses health equal to the stamina die.
On a successful save, the target loses half as much health and the effect ends.
If the creature regains health while bleeding, the bleeding ends.
This has no effect on any creature that cannot bleed or lose a vital liquid substance.
You can increase the damage for each additional stamina die expended.
