Boon of the Phoenix

When you would receive fire damage, you instead heal for half the amount of damage that would be dealt to you.

Fire Form. The recipient of this boon can move through a space as narrow as 1 inch wide without squeezing. Any creature that touches the phoenix or hits it with a melee attack while within 5 feet of it takes 5 (1d10) fire damage. In addition, the recipient of this boon can enter a hostile creature’s space and stop there. The first time it enters a creature’s space on a turn, that creature takes 5 (1d10) fire damage. With a touch, the recipient of this boon can also ignite flammable objects that aren’t worn or carried (no action required).

Fiery Death and Rebirth. When the recipient of this boon dies, it explodes. Each creature within 60-feet of it must make a DC 20 Dexterity saving throw, taking 22 (4d10) fire damage on a failed save, or half as much damage on a successful one. The fire ignites flammable objects in the area that aren’t worn or carried.

The explosion destroys the recipient's body and items and leaves behind an egg-shaped cinder that weighs 5 pounds. The cinder is blazing hot, dealing 21 (6d6) fire damage to any creature that touches it, though no more than once per round. The cinder is immune to all damage, and after 1d6 days, it hatches a new Phoenix. Due to the strain put on the Phoenix’s soul, this forces a new prestige, requiring a small tattood Roman numeral on their body to increase by one. The tattoo can be placed wherever this boon recipient wishes.
