As a bonus action when you hit a creature with a melee weapon attack made with a natural weapon that deals piercing or slashing damage, you can tear into your foe to produce jagged wounds, 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 undead, constructs, or any creature that cannot bleed.
You can increase the damage for each additional stamina die expended.
