Instant Fortification

Through this spell, you transform a miniature statuette of a keep into an actual fort. The fortification springs from the ground in an unoccupied space within range. It is a 10- foot cube (including floor and roof). Each wall has two arrow slits. One wall also includes a metal door with an [arcane lock](https://api.open5e.com/spells/arcane-lock) effect on it. You designate at the time of the fort’s creation which creatures can ignore the lock and enter the fortification. The door has AC 20 and 60 hit points, and it can be broken open with a successful DC 25 Strength (Athletics) check. The walls are made of stone (AC 15) and are immune to necrotic, poison, and psychic damage. Each 5-foot-square section of wall has 90 hit points. Reducing a section of wall to 0 hit points destroys it, allowing access to the inside of the fortification.
