Ballista

These large interactive, stationary weapons that resemble enormous crossbows can be found in some locations throughout the Shiverpeak mountains. They are fired using a lever and automatically recharge after being fired. Most ballistae break when enemy NPCs manning them are killed, but others are usable by players.
