Barrier of Pure Thought

A barrier of pure thought springs into reality at a point you choose within range. You can shape the wall however you like, including a dome or a sphere with a radius of 10 feet. Or you can shape a wall that is 80 feet long, 20 feet high, and 1/4 inch thick. If the barrier cuts through a creature's space when it appears, the creature is pushed to one side of the wall (your choice which side) and must succeed on an Intelligence saving throw or take 4d6 psychic damage.

Nothing can physically pass through the wall. It 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.
