Black Coffin

With an incantation, raven-like walls of midnight rise up before closing in on the target area, distorting space and time and rending everything inside with dark energy.

A 100-foot cube within range forms, blocking movement, line of sight, and effect. Every creature within the cube must make a Constitution saving throw: on a fail, they are removed from play, and take 12d12+spellcasting ability modifier Necrotic damage. When the spell ends the targets return to play in their space or the nearest available one, and are Frightened for one minute.
