Forcecage

Materials: You require Ruby Dust, typically valued at 1500 gold. This spell consumes the material.

Utility

• You create an immobile, invisible, cube-shaped prison of magical force. The prison may be either a cage or a solid box. The cage extends into the Ethereal Plane, blocking ethereal travel.
  • Cage: Up to 20 ft. on a side, formed by 1/2-inch diameter bars spaced 1/2 inch apart. A creature inside the cage cannot leave by nonmagical means.
  • Box: Up to 10 ft. on a side, a solid barrier that blocks matter and prevents spells from passing into or out of the area.
• Creatures fully inside the area are trapped. Creatures partially inside, or too large to fit, are pushed outward until completely outside the area. If a creature attempts to teleport or use interplanar travel, it must first succeed on a Charisma saving throw.
• This spell cannot be dispelled by dispel magic.

Charisma Save

• Failure: The attempt fails, the magic is wasted, and the creature remains trapped.
• Success: The creature may exit the forcecage using that magic.
