Alti's Astral Singularity

A tiny black orb flies from you palm or focus to a point you choose within range and then expands with a low roar into a sphere of infinite density and gravity. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. each target in the area takes 6d8 force damage, is moved to the point the spell was cast at, and is restrained until the end of their turn on a failed save, and take half as much damage and suffers no additional effects on a successful one.

Objects that are small or smaller in the area of effect are automatically moved, no matter the save.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
