Warding Moon

With gently guiding motions, you weave together motes of moonlight into a miniature moon, which hovers serenely in the air, bathing its surroundings in gentle radiance.

You create a floating, spectral moon within range which lasts for the duration of the spell. It sheds dim light in a 20-foot radius sphere. Any allies within this light gain advantage on saving throws against spells and other magical effects, and spell attacks have disadvantage against them. As a bonus action, you may move the moon up to 20 feet.

While the spell is active, you may spend a bonus action to cause the moon to burst into an explosion of silver flame. All creatures within the light must make a Dexterity saving throw. A target takes 6d6 radiant damage on a failed save, or half as much damage on a successful one. This ends the spell.

At Higher Levels. When you cast this spell using a slot of 6th level or higher, the radius of the light increases by 5 feet for each slot above 5th.
