A black wall of Oblivion energy springs into existence at a point you choose within range. The wall appears in any orientation you choose, as a horizontal or vertical barrier or at an angle. It can be free floating or resting on a solid surface. You can form it into a hemispherical dome or a sphere with a radius of up to 10 feet, or you can shape a flat surface made up of ten 10-foot-by-10-foot panels. Each panel must be contiguous with another panel. In any form, the wall is infinitely thin. It lasts for the duration. If the wall cuts through a creature”s space when it appears, the creature takes 5d8 force damage. On a successful Dexterity save, a creature takes half damage.
Anything passing through the wall takes 5d8 force damage, including anything carried. A creature thrown or otherwise moved toward the wall against their will can make a Dexterity save for half damage. Anything reduced to 0 hit points is disintegrated. It is immune to all damage but can be dispelled by a high enough dispel magic. The wall also extends into the Ethereal Plane, blocking ethereal travel through the wall.
