Unyielding

Your heart harbors the will of Arborea, and you will fight until your last breath to protect it

- When you reduce a creature to 0 hit points with a melee weapon attack, you regain HP equal to your Constitution Modifier + Your Proficiency Bonus

- When you are reduced to 0 hitpoints but not killed outright, you may use your reaction to make a melee weapon attack against a creature within range, if the attack hits, you reduced to 1 hit point instead, and gain temporary HP equal to the Damage Dealt. You can’t use this feature again until you finish a short or long rest.
