You choose a Medium or smaller creature you can see within range and conjure a sarcophagus around it, which lasts for the duration. The target must succeed on a Dexterity saving throw or be trapped inside the sarcophagus. While trapped, the target is blinded and restrained and has full cover from attacks originating outside the sarcophagus. Likewise, creatures and objects outside the sarcophagus have full cover from the trapped target.
A trapped creature can use its action to make a Strength check against your spell save DC, ending the spell on a success. The sarcophagus can also be destroyed by dealing damage to it, ending the spell (AC 17; hp 20; damage threshold 10; immunity to poison and psychic damage).
If you concentrate on this spell for the full possible duration, the spell lasts until it is dispelled or until the sarcophagus is destroyed.
