You call upon the power of the phoenix and undergo a transformative rebirth, immediately regaining 1 hit point. Your body is consumed in flames, providing you immunity to all damage until the start of your next turn, at which point you rise from the ashes with wings of fire, gaining the following benefits for the duration:

• You have resistance to fire damage.
• You have a flying speed of 40 feet.
• You can use your action to unleash a burst of flames. Each creature within 15 feet of you must make a Dexterity saving throw, taking 6d6 fire damage on a failure, or half as much on a success.
• You can use your bonus action to regain a number of hit points equal to your level + your spellcasting ability modifier. You can do so up to three times for the duration of the spell.

After you use this spell, attempting to cast it again before you finish a long rest causes you to be instantly disintegrated, reduced to a pile of fine dust.
