Ahmose's Falling Moons

You choose three points within range of this spell and three miniature moons fall into selected points. Once a moon reaches its destination or impacts against a solid surface, the moon crushes. Each creature within 10 feet of the point where the moon crushes must make a Dexterity saving throw. A creature takes 2d8 bludgeoning damage on a failed save and is knocked prone, or half as much damage on a successful one, and is not knocked prone. A prone creature automatically fails this saving throw. If a creature is hit with more than one moon, it only needs to make a Dexterity saving throw for the first one, its result also applies to subsequent impacts.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the number of moons increases by one for each slot level above 4th.
