Comet

You pull a minor comet out of orbit, causing it to plummet towards a point you can see within range. Creatures with a Passive Perception greater than your spell save DC instantly become aware of the glowing orb that appeared in the sky. Roll a d6 at the end of your later turns until the comet lands. The first time you roll, the comet lands on a 6. The second time you roll, the comet lands on a 5 or a 6, and so on.

When the comet lands, each creature in a 30 foot sphere centered on the point is pushed up to 15 feet away from the point and must make a Dexterity saving throw. A creature takes 6d8 bludgeoning damage and is knocked prone on a failed save. A creature takes half of the damage on a successful save. The comet shatters on impact and creatures in a 15 foot sphere of the point that fail the saving throw are not pushed away, but take an additional 6d8 bludgeoning damage and become restrained by debris. To break out, a restrained creature can use its action to make a Strength check against your spell save DC.

The spell creates difficult ground and damages objects in the area. Each 5-foot-square portion of the area requires at least 1 minute to clear by hand.
