Arcane wall

An invisible wall of force 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 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. Each panel
has an AC of 10 + the spell's level (15) and has 20 hit points
per level of spell (100). The wall can't be dispelled by dispel
magic, and is immune to psychic and nonmagical
bludgeoning, piercing, and slashing damage. A disintegrate
spell destroys the wall instantly, however. The wall also
extends into the Ethereal Plane, blocking ethereal travel
through the wall.
