Undying Will

Your determination and tenacity to live pushes you beyond the point of brake.   

• Increase your Constitution by 1, to a maximum of 20.

• Your will to live makes you difficult to defeat. On a successful death save, you can make a Constitution saving throw (DC 8 + Attacker's proficiency bonus + Attacker's ability modifier  to damage). On a success, you stabilize gaining 1 hit point. You can't use this feature if you are reduced to 0 hit points by a critical hit.

  After the saving throw succeeds, you can't use this feature again until you finish a long rest.
