Demigon’s Black Coffin

Create a container around a large or smaller creature with an AC and HP of 10 + your casting mod. Creatures inside are unaffected by Aoe effects outside. The container cannot be damaged from the inside. Effects and attacks originating inside cannot affect anything outside. At the beginning of the target’s turn, they may make a strength save to escape. Upon casting, you may move the coffin and the target inside up to 60 ft. through the air in any direction, where it stays unless moved by something else.
