Artificial Singularity

You create a temporary singularity at a point you can see within range. It manifests as a 20-foot-radius sphere of impossible density.

When the spell is cast, each creature within 60 feet of the sphere must make a Strength saving throw. On a failed save, a creature is pulled up to 30 feet toward the sphere and takes 10d10 force damage. On a successful save, it takes half as much damage and is not pulled.

Until the spell ends:

• The area within 60 feet of the sphere is difficult terrain.
• A creature that starts its turn within 60 feet of the sphere must make a Strength saving throw. On a failed save, it is pulled 20 feet toward the center and takes 6d10 force damage. On a successful save, it takes half as much damage and is not pulled.
• A creature that enters the sphere’s space for the first time on a turn or starts its turn there takes 12d10 force damage automatically.
• Ranged weapon attacks and spell attacks that pass within 20 feet of the sphere are made with disadvantage.

As an action on your turn, you can move the sphere up to 20 feet.

If the sphere reduces a Huge or smaller nonmagical object or structure section to 0 hit points, that matter is crushed into ruin.

When the spell ends, the sphere collapses in a final shockwave. Each creature within 30 feet of it must make a Dexterity saving throw, taking 6d10 force damage on a failed save, or half as much damage on a successful one.
