World versus World
Siege weapon

A trebuchet is a World vs World siege weapon that fires explosive shots or tainted cows over long distances of up to 10,000 units. The primary purpose of trebuchets is to destroy walls over distances too large for a catapult, although they can also deal reduced damage to gates and infantry, and cause a knockback effect. Alternately, the trebuchet can be loaded with tainted cows, which deal no damage but create a poison cloud.

Trebuchets also deal significant damage to enemy siege weapons, making them useful for defense in a similar manner to mortars.

Superior trebuchets deal 50% more damage than regular trebuchets and require an additional 20 Supply.png (120 total) to build. They are built with Superior Trebuchet Blueprints, which are made in the mystic forge.

Guild trebuchets are functionally the same as superior trebuchets. They can be built with Guild Trebuchet Blueprints, which are purchased for 12 Silver coin + 3 Guild Commendations from a guild commendation trader.



Gwwlogo.png The Guild Wars Wiki has an article on Trebuchet.
  • The range of trebuchets is affected by their elevation; placing them higher up will allow the shot to travel further.
  • Trebuchets can be rotated to face any direction, although they are slow to turn completely around - bear this in mind before deployment.
  • A trebuchet has a health of ~80,700, and does 9,715 damage to regular walls, 4,857 to fully upgraded walls.[1]
