Mending Affinity

Your body has begun to adapt extremely well to healing itself through extraordinary means, gifting, you the following benefits:

• Your Constitution score by 1, to a maximum of 20.
• When a creature stabilizes you when you are dying, you can spend your reaction and spend Hit Dice to heal yourself, as if you have taken a short rest. Once you use this feature, you can’t use it again until you finish a long rest.
• Whenever you regain hit points from any source, you regain additional hit points equal to your proficiency bonus.
