As an action, make a melee weapon attack with a light or finesse weapon to slice the creature’s tendon.
On a hit, add one stamina die to the attack’s damage and the creature must succeed on a Fortitude saving throw or it is slowed 1 for the duration and while affected it loses health equal to one of the stamina dice for every meter it travels. This has no effect on any creature that cannot bleed or lose a vital liquid substance.
On a critical hit, add twice as much damage.
On a miss by 4 or less, add half as much damage.
The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
You can increase the damage for each additional stamina die expended and the slowed level by 1 for every two additional stamina die expended.
