Astral Cage

Opening the chest forces the nearest creature in a 15 ft cone to make a DC 15 Strength saving throw or be sucked into the chest. The chest can only hold one large or smaller creature. If there is already a creature in the chest they are replaced with the creature that failed the strength saving throw. The chest can only be opened by a creature and cannot be opened from the inside except with a successful DC 25 intelligence (arcana) check. A creature in the chest floats in an astral demi plane. The creature perceives time to flow normally but they don’t age and do not need to breathe or eat.
