These are powerful and destructive weapons that lob large rocks into the air, sending them crashing through enemy ranks. Many races in Warhammer use these devices. Not all are built in the same way: some use a massive counterweight to catapult their missile into the air while others use torsion power like a giant crossbow. The bigger the engine, the larger the rock it can throw and the more damage it can do. The very largest stone throwers can hurl a projectile big enough to flatten the most powerful of monsters or knock down city walls!
