Ashlanar's Grace

A dome of pure light surrounds you in a 10-foot-radius. No aberration, elemental, fey, fiend and undead can enter the dome, if any of these creatures are within the radius when the spell is cast they take 4d10 radiant damage and are pushed back 20ft and knocked prone. Spells cannot enter the dome or be cast within the dome unless the spell draws power from the light. Any creature within the dome will heal 1d8 each round. Until the spell ends, your speed is reduced by 10 feet however the sphere moves with you, centered on you.
