As an action, make a weapon attack to menace the creature, foiling its attacks and punishing them for harming others.

On a hit, add the stamina die to the attack’s damage and the creature must succeed on a Will saving throw or it is marked by you for the duration. While marked, you have advantage on opportunity attacks made against the target and the target has disadvantage on any attack that doesn’t target you.

On a critical hit, add twice as much damage.

On a miss by 4 or less, add half as much damage.

The effect ends if you are incapacitated, someone else marks the creature, you attack or damage any other creature, if you cast a spell or use a spell that targets a hostile creature other than the target, if a creature friendly to you damages the target or casts a harmful spell on it, or if you end your turn more than 5 meters away from the target.

Enhance

You can increase the damage for each additional stamina die expended.
