The Astrality of Alithea

You open a gateway to the heart of a star, a space suffused with purity and hope. A 20-foot-radius sphere of light and gentle heat appears, centred on a point with range and lasting for the duration. This orb is filled with a chorus of soft angelic voices that can be heard up to 30 feet away. No darkness, magical or otherwise, can affect the area.

The sphere creates a warp in the fabric of space, providing respite and restoration for those within. Any creature that starts its turn in the area regains 2d6 hit points. Any creature that ends its turn in the area receives the benefits of half cover, and has advantage on saving throws against charm and frightened effects.

At higher levels: when you cast this spell using a spell slot of 4th level or higher, the healing increases by 1d6 for every level above 3rd.
