Dungeons and Dragon Ball (Ver. O.1)

An immobile, Invisible, Cube-shaped prison composed of ki springs into existence around an area you choose within range. A prison in the shape of a cage can be up to 20 feet on a side and is made from 1/2-inch diameter bars spaced 1/2 inch apart. A prison in the shape of a box can be up to 10 feet on a side, creating a solid barrier that prevents any matter from passing through it and blocking any spells cast into or out of the area. When you cast the spell, any creature that is completely inside the cage’s area is trapped. A creature inside the cage can’t leave it by nonmagical means. If the creature tries to use teleportation or interplanar travel to leave, it must first make a Charisma saving throw. On a successful save, the creature can use that magic to exit the cage. On a failed save, the creature doesn’t exit the cage and wastes the spell or effect.
