Wall of Runes

A shimmering wall of runic sigils 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. 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).
Nothing can physically pass through the wall. It has an AC of 15, and HP of 20. It can dispelled by dispel magic, or stopped by any type of negation spell. A disintegrate spell destroys the wall instantly, however.
