Prismatic Wall

Utility

• You conjure a shimmering, multicolored wall of light. Choose either a vertical opaque wall (up to 90 ft. long, 30 ft. high, 1 in. thick) or a 30-ft. sphere.

• The wall sheds bright light to 100 ft. and dim light for another 100 ft.

• Allies designated at the time of casting can pass freely without harm.

• Creatures passing through the wall do so one layer at a time, making saving throws against each layer. Look at wall layers below.

• The wall can only be destroyed layer by layer, from Red to Violet. Antimagic Field has no effect. Dispel Magic only works against the Violet layer.
