Instant Fortress

A small metal cube which can transform into a metal tower 30’ tall and 20’ square.

• Command words: One command word activates the tower and another deactivates it, returning it to the form of a small metal cube.

• When activated: The tower springs up in 1 round. Any (except the owner) within 20’ must save versus paralysis or suffer 10d6 damage.

• Exterior: The fortress has 3 storeys, arrow slits on all 4 sides, a single entrance door at ground level, and a crenellated battlement atop it.

• Entering: The door only opens at the owner’s command. Knock spells cannot open it.

• Inside: Stairs lead to each of the 2 upper storeys and the battlement.

• Damaging: The tower is treated as a vehicle (see Vehicles in Old-School Essentials Classic Fantasy) with AC 5 [14] and 40 hull points. Only a wish can repair it (2 hull points per wish).

• Deactivating: The fortress can only be deactivated when it is empty.
