Wall of Wit

An invisible wall of intellect 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 15-foot-by-15-foot panels. Each panel must be contiguous with another panel. In any form, the wall is 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).

When ever something tries to move through your wall including yourself and allies, they must make an intelligence saving throw against twice your Spell save DC, on a success they can pass through a wall.On a failed save they can't pass through the wall and then must make a wisdom saving throw against half your spell save dc, On a failed save they take 2d4 Psychic damage, and nothing else happens if they succeed the second save.
