Void Rift

9th-level void magic

Casting Time:1 action

Range:300 feet

Components:V, S, M (a black opal carved with a void glyph worth 500 gp)

Duration:Concentration, up to 1 minute

You speak a hideous string of void speech that leaves your mouth bloodied, causing a rift into absolute nothingness to tear open. The rift takes the form of a 10-foot-radius sphere, and it forms around a point you can see within range. The area within 40 feet of the sphere’s outer edge becomes difficult terrain as the void tries to draw everything into itself. All creatures that start their turns within 40 feet of the sphere or that enter that area for the first time on their turn must succeed on a Strength saving throw or be pulled 15 feet toward the rift. Creatures that start their turn in contact with the rift or that come into contact with it for the first time on their turn take 8d10 necrotic damage. Creatures inside the rift are blinded and deafened. Unattended objects within 40 feet of the rift are drawn 15 feet toward it at the start of your turn, and take damage as creatures.

While concentrating on the spell, you take 2d6 necrotic damage at the end of your turn.
