Wall of Spatial Shifting

A wall that is a portal  springs into existence at a point you choose within range. The wall is 6 inches thick and is composed of ten 10-foot- by-10-foot panels. Each panel must be contiguous with at least one other panel. Alternatively, you can create 10-foot-by-20-foot panels that are only 3 inches thick.

If the wall cuts through a creature's space when it appears, the creature is pushed to one side of the wall (your choice). If a creature would be surrounded on all sides by the wall (or the wall and another solid surface), that creature can make a Dexterity saving throw. On a success, it can use its reaction to move up to its speed so that it is no longer enclosed by the wall.

The wall can have any shape you desire, though it can't occupy the same space as a creature or object. The wall doesn't need to be vertical or rest on any firm foundation.

The wall is a one way portal which leads to a harmless pocket dimension, if a creature or object were to enters the portal it will be transported to this pocket dimension. The creature remains in the pocket dimension until the spell is dispelled or if the duration ends. When the spell ends, anything inside will be harmlessly dropped in the open space within 5 ft of the Wall of Spatial Shifting
