Time Prison

As you raise your hand, and begin to cast a spell, select one target in your range. As you begin to speak in Astral language and begin to name words such as Time, Prison, Hold, multiple fractions in time begin to show up around the target and make a sphere.

The 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. In any form, the wall is 1/4 inch thick. 

All enemy creatures within the sphere must make a Wisdom saving throw, on a failure the creature is stunned. The creatures may make another save at the start of each turn it is trapped in the sphere. The sphere 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. On success they may just walk through the wall.
