As an action, make a weapon attack to leave a twisted wound that can’t be healed so easily.

On a hit, add the stamina die to the attack’s damage and the creature must succeed on a Fortitude saving throw or its maximum health is reduced by the stamina die result for 1 hour. Any effect that removes a condition allows a creature’s maximum health to return to normal before that time passes.

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 for each additional stamina die expended.
