Instant Fortress
Wondrous Item, Rare (Requires Attunement)
As a Magic action, you can place this 1-inch adamantine statuette on the ground and, using a command word, cause it to grow rapidly into a square adamantine tower. Repeating the command word causes the tower to revert to statuette form, but only if the tower is empty. Creatures in the area where the tower appears are pushed to an unoccupied space next to it, and unattended objects are similarly displaced.
The tower measures 20 feet on each side and stands 30 feet high, with arrow slits on all sides and a battlement on top. Inside, the tower has two floors connected by your choice of a ladder, staircase, or ramp, ending at a trapdoor leading to the roof. When formed, a single door appears at ground level on the side facing you. The door opens only at your command, issued as a Bonus Action, and is immune to the Knock spell and similar magic.
Magic prevents the tower from being tipped over. The roof, door, and walls each have AC 20, 100 Hit Points, Immunity to Bludgeoning, Piercing, and Slashing damage (except from siege equipment), and Resistance to all other damage. Shrinking the tower back to statuette form does not repair any damage. Only a Wish spell can restore the tower’s Hit Points, counting as replicating an 8th-level or lower spell. Each casting of Wish fully repairs the tower.
