Vara's Rising Phoenix

As a part of casting this spell, the caster rises up to 15 feet into the air, this movement does not provoke opportunity attacks. Each creature within 5 feet must make a Dexterity Saving Throw or take 6d6 Fire Damage, or half as much on a successful save. As a Bonus Action within the next minute, the caster may use a bonus action to return 15 feet to the ground with a healing slam, dealing 6d6 healing to creatures within 5 feet of the space where they land. The spell then ends.
