Casting Time: 1 Action
Range: 120 feet
Components: V, S, M (piece of obsidian, shattered in the casting)
Duration: Concentration, up to 10 minutes
You create a wall of absolute darkness on a solid surface within range. You can form it into a hemispherical dome or sphere with a radius of up to 10 feet, or you can shape a flat surface made up of ten 10-foot-square panels. Each panel must be contiguous with another panel. Regardless of form, the wall is 1 foot thick and lasts for the duration. No light passes through the wall.
If the wall appears in a creature’s space when it appears, the creature in that space is shoved to your choice of one side of the wall or the other and must make a Constitution saving throw. On a failed save, the creature takes 4d6 necrotic damage and 4d6 cold damage and gain a level of exhaustion. A creature that succeeds on its save takes half as much damage and does not gain an exhaustion level. A creature takes this same damage when it enters the wall for the first time on a turn or ends its turn there.
Any nonmagical light source that touches or enters the wall is immediately extinguished.
A magical light ceases producing light as long as it remains within the wall’s space.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d6 for both cold and necrotic damage for every two slot levels above 5th.
