You target a dwelling and create a hidden room that only you can enter. The entrance is located in a corner of two walls, behind a door or under furniture. The hidden room is 15ft by 15ft and has a bed, cooking supplies, a desk and chair, and a water source. You can invite others into the room. If the spell ends with any objects or creatures inside then they are expelled violently into available space and take 2d8 bludgeoning damage.
