Dark Matter

You invoke the unfathomable power of dark matter, bending gravity and entropy itself to consume the battlefield. A 20-foot-radius sphere of crushing, unseen energy manifests at a point within range. This void absorbs light, distorts space, and pulls all within it toward oblivion. Creatures caught within the sphere suffer the following effects:

• Creatures within the sphere must make a Strength saving throw against your spell save DC or take 10d6 force damage and their movement is halved, taking half damage and their movement unrestrained on a successful save
• Projectiles and ranged attacks that pass through or originate from the sphere are made at disadvantage as the trajectories become warped by the sphere's influence. Ranged spells that require a hit roll automatically fail if the target is within the sphere.
• Teleportation is hindered within the sphere, any creature attempting to teleport requires a successful Intelligence saving throw, or the spell fails and is wasted.

Restrained creatures can repeat the saving throws at the start of their turns. Creatures who fail repeated saving throws take an additional 4d6 force damage.

At higher levels. Radius of the sphere increases by 10 ft. for each level above 7th.
