Ardahn's Great Sealing

You seal a creature within range inside of an object at least 10 ft. x 10 ft. in size that you are touching. When sealed by this spell, all parts of a target's body and soul are also sealed inside the object, regardless of location. While sealed by this spell, the target has the Unconscious condition and cannot be harmed. The effect of this spell lasts indefinitely and can only be dispelled due to the death of the caster or the destruction of the sealing object.
