Wall of Mana

4th-level transmutation

Casting Time:1 action
Range:20 feet
Components:V, S, F
Duration:Concentration, up to 1 minute

Drawing on the defensive principles and properties of the Pool of Magic, you create a barrier of raw mystical energy. An invisible wall of magical 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 1/4-inch thick. It lasts for the duration. If the wall cuts through a creature’s space when it appears, the creature is pushed to one side of the wall (your choice which side).

Spells cast from the side of the wall where you stand pass through the wall normally. Spells of 4th level or lower cast in your direction from the side of the wall opposite you are stopped by the wall, their magical energy harmlessly impeded by the wall. The wall is immune to all damage and can’t be dispelled by dispel magic. A disintegrate spell destroys the wall instantly, however. The wall also extends into the Ethereal Plane, blocking ethereal travel through the wall.

At Higher Levels. When this spell is cast using a spell slot of 5th level or higher, it impedes spells of the level at which it is cast and lower from passing through the wall.
