Description:
An immobile, invisible, cube-shaped prison composed of magical force springs into existence around an area you choose within range. The prison is in the shape of a box that can be up to a 2×2 foundation square, creating a solid barrier that prevents any matter from passing through it and blocking any spells cast into or out from the area.

When you cast the spell, any creature that is completely inside the cage’s area is trapped. Creatures only partially within the area, or those too large to fit inside the area, are pushed away from the center of the area until they are completely outside the area.

A creature inside the cage can’t leave it by non-magical means. The cage also extends into the Ethereal Plane, blocking ethereal travel.

This spell can’t be dispelled by dispel magic. (All victims of this spell are exempt from consequences.)

If used in mechanical PVP this creature may not be displaced by any means until the end of the spell phase and may fight normally upon the end of spell phase.
