Wall of Gloom

Rubbing the fleece between your fingers, you hold up your hand and shout an arcane word. In an instant, a wall of dark shadow appears in the indicated location. Dark whispers, barely perceptible, constantly issue forth from the far side of the wall, causing a cold chill to run up your spine.

You create a straight barrier of ominous shadow that is 40 ft long and 20 ft tall that obscures vision and blocks line of sight, including darkvision. The wall is insubstantial, so creatures can move through it without penalty. Wall of gloom counters or dispels any light spell of equal or lower level.
