Barrier

You create a crystalline barrier at a point you can see within range. The barrier can be placed in any orientation you choose. It can be free floating or resting on a solid surface. The barrier is a clearly visible color of your choice, but see-through. The barrier is a 10-foot-by-10-foot panel and is 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 barrier (you choose which side).

Nothing can physically pass through the barrier. Spells and magic can travel through the barrier as if it were not there. It is immune to all damage. A Disintegrate or Dispel Magic spell destroys the barrier instantly.
