Summon Asteroid

6th-level conjuration

Classes: druid, wizard

Casting Time: 1 action

Range: 250 miles

Components: V, S, M (a diamond worth 500 gp)

Duration: Instantaneous

You conjure an asteroid within range. The asteroid is composed of ten contiguous 10-foot cubes of rock arranged as you desire. If you conjure the asteroid within range of a larger object, the asteroid assumes a stable orbit around that object. If you attempt to summon the asteroid outside of stable orbit, but within the gravity well of a larger object such that it falls into that object, the spell fails.

When created, the asteroid has no atmosphere, though it has sufficient mass to hold an air envelope if one is provided.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, you increase the size of the asteroid by ten cubes for each spell level about 6th.
