An invisible wall of force appears at a point you specify within casting distance. The direction of this wall of force is up to you: you can make the wall horizontally or vertically bounded, or you can make it incline at an angle. It can float in the air or stand on the ground.
Wall of Force 5e
Casting Time: 1 Action
Range: 120 feet
Components: V, S, M
Duration: Concentration, up to 10 minutes
It can be shaped as a hemisphere or a sphere (with a radius of up to 10 feet), or as a plane of ten 10 ft x 10 ft square plates, each of which must be connected to at least one other plate.
Regardless of the shape, the force field wall is always ¼ inch thick. The force field wall will persist until the spell ends. If the force wall forms through a space occupied by a creature, that creature is pushed to one side of the force wall (it is up to you to decide which side to push to).
Nothing can physically pass through a wall of force. A Wall of Force is immune to all damage and cannot be undone by dispel magic, but the spell disintegrate can cause it to be destroyed immediately. Walls of force can extend into the Etheric plane, and thus can block travel into the Etheric plane through walls.
