Create a physically insurmountable wall of force (ten 10-ft panels) immune to all types of damage.

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 10-foot-by-10-foot panels. Each panel must be contiguous with another panel. 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 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.

Unnoticed by the uninitiated, your whispered incantation births an unseen barrier—a mystical shield imperceptible to the untrained eye. Smirking inwardly, you revel in the power concealed within your breath, creating an invisible bulwark capable of thwarting assaults, intruders, and sorceries alike.
