Wall of Air

4th-level transmutation

Casting Time:1 action
Range:120 feet
Components:V, S, M (a pinch of quartz dust, a small horn)
Duration:Concentration, up to 10 minutes

You create a wall of swirling air. The wall forms in any orientation you desire, 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 10 feet, or you can shape a flat surface made of 10 by 10 foot panels. Each panel must be contiguous with another panel. The wall is six inches thick and lasts for the duration of the spell, dissipating as a strong breeze when the duration ends.

If the wall cuts through a creature’s space when it is formed, the creature is pushed to one side of the wall and must succeed at a Dexterity save or suffer 5d6 slashing damage, half damage with a successful save. The wall is clear, but blocks effects and attacks that attempt to pass through it, as well as creatures.

The wall is a physical object with AC 10 and 20 hit points per 10 by 10 foot section. Reducing a section of a wall to 0 hit points destroyed it and leaves behind a blue-white field of elemental energy. A creature passing through this sheet for the first time on a turn must succeed at a Constitution save or suffer 2d6 lightning damage (half damage with a successful save).

At higher levels. When this spell is cast using a spell slot of 5th level or higher, the damage the wall inflicts through any effect increases by 1d6.
