Dungeons in Darkness
Heward's Hardy Habitation
Magical Shelter Designed for Support in Virtually Any Enviroment
You can use an action to place this 1-inch metal cylinder on the ground and speak its Command Word. The cylinder rapidly grows into a large command outpost that remains until you use an action to speak the Command Word that dismisses it, which works only if the command outpost is empty.
The command outpost is a short silo-like tower, 10 feet around and 15 feet high, with 4 slender windows equidistant from one another, that can remain completely sealed to outside environmental effects and there is a crow’s nest atop it with similar environmental seals though the crow’s nest can be opened from the inside, in four separate sections, as an action. A ladder, next to a smokeless everburning stove leads up to the small landing of the crow’s nest which can comfortably fit/support two medium sized creatures. When activated, the tower has a small door on the side facing you. The door opens only at your Command, which you can speak as a Bonus Action. It is immune to the knock spell and similar magic, such as that of a Chime of Opening.
Each creature in the area where the fortress appears must make a DC 15 Dexterity saving throw, taking 5d10 bludgeoning damage on a failed save, or half as much damage on a successful one. In either case, the creature is pushed to an unoccupied space outside but next to the fortress. Objects in the area that aren’t being worn or carried take this damage and are pushed automatically.
The tower is made of adamantine, and its magic prevents it from being tipped over. The roof, the door, and the walls each have 50 hit points, immunity to damage from nonmagical Weapons excluding siege Weapons, and Resistance to all other damage. Only a wish spell can repair the fortress (this use of the spell counts as replicating a spell of 8th level or lower). Each casting of wish causes the roof, the door, or one wall to regain 25 hit points.
