Aspect of the Firebird

6th-level transmutation

Casting Time: 1 action
Range: Self
Components: V, S, M (a lit candle and the tail feather of a bird)
Duration: Concentration, up to 8 hours

You take on the aspect of a firebird, including some physical attributes. A fiery mantle descends upon you, resembling feathery wings and an expansive tail. You gain immunity to fire and a flying speed of 60 feet. Any creatures within 5 feet of you gain immunity to natural, environmental cold.

As an action, you can emit a blast of light 5 feet wide and 50 feet long. All creatures in its path take 6d6 fire damage and are blinded for 1d4 rounds. A successful Dexterity saving throw reduces the damage by half and negates the blindness. Each time you use this feature of the spell, its duration is reduced by 1 hour. When you expend the last hour of the duration, the spell ends at the start of your next turn.
