As you spend 1 minute to cast this spell, you create a magical restraint to hold a creature that you can touch or see within 5 meters. The target must succeed on a Will saving throw or be entombed far beneath the earth in an air pocket that is just large enough to contain the target. Nothing can pass through the pocket, nor can any creature teleport or use planar travel to get into or out of it. If it succeeds, it is immune to this spell if you cast it again.
While affected by this spell, the creature doesn’t need to breathe, eat, or drink, and it doesn’t age. Divination spells can’t locate or perceive the target.
Ending the Spell. During the casting of the spell, you can specify a condition that will cause the spell to end and release the target. The condition can be as specific or as elaborate as you choose, but the GM must agree that the condition is reasonable and has a likelihood of coming to pass. The conditions can be based on a creature’s name, identity, or deity but otherwise must be based on observable actions or qualities and not based on intangibles such as level, class, or health.
A dispel magic spell can end the spell only if it is cast using 5 mana.
