As an action, make a melee weapon attack with a natural weapon that deals piercing or slashing damage to cause jagged wounds that bleed.
On a hit, add the stamina die to the attackās damage and the creature is bleeding 1.
On a critical hit, add twice as much damage.
On a miss by 4 or less, add half as much damage.
Enhance
You can increase the damage and bleeding level by 1 for each additional stamina die expended.
