Catapult
"Took them long enough." —Ma' Ngonel
Brings down walls and buildings, and rolls. Only troops can build it.
Select it and click an enemy: it aims at it and its crew pushes it there. It doesn’t fire while it moves. It fires until nothing is left to hit, and its stones hurt every enemy near where they land. Shots land a little off target.
It needs siege stones from the Stone Press. The crew fetch them, or haulers bring them while it’s within 5 tiles of your roads (see Ammunition).
