Circle of Rebirth

You gain access to several abilities through your devotion to the rejuvenating flame that grant you the power to restore others and revive that which was lost. Strong enough druids that follow this circle become able to transform into phoenixes and their lesser forms.

Fiery Rebirth

You gain access to the spell Fiery Rebirth, and can use it once per long rest.

Feathered in Flame

You have natural resistance to fire damage.

Blazes of Nature

You gain the ability to not only restore your allies, but also burn your enemies to cinders.

Power of the Phoenix

You gain access to more powerful versions of your ability Blazes of Nature.

Born Anew

After dying, you have the ability to wild shape into a Reduced Threat Phoenix until your wild shape breaks, or into a Phoenix for 1d4 turns, and then you will return to 1 HP. You will be reborn in your races' prime, and with all spell slots 3rd level and below, as well as subclass ability charges being restored. 

You may not use this ability without having first revived someone with Fiery Rebirth, nor may you use it again without having done so, plus a long rest.
