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.

Usage

• Building a trebuchet requires an Trebuchet Blueprint or an Infinite Trebuchet Blueprint and consumes 50  to complete.

Trivia

The Guild Wars Wiki has an article on Trebuchet.

• Historical information up to the November 19, 2024 update:
  • Basic trebuchets were built with Trebuchet Blueprints, which can be bought from a Siege Master for either 24  or 24 . Once deployed, the build site required 50 .
  • Superior trebuchets deal 50% more damage than regular trebuchets. They were built with Superior Trebuchet Blueprints, which were made in the mystic forge, bought from various merchants, and found in various containers, the build site required 60 .
  • Guild trebuchets were functionally the same as superior trebuchets. They were built with Guild Trebuchet Blueprints, two of which may be purchased for 12  + 3 from a Guild commendation trader or crafted by level 400 Scribes. They require 50  to build.
