Let me explain some of the process. It all starts with a base weapon—these are the extremely rare exotic weapons. Once you’ve obtained your base weapon, you’ll need to present gifts to Zommoros, a powerful djinn who lives in Lion’s Arch. These gifts come from all over Tyria, and you’ll need different ones depending on what Legendary Weapon you’re trying to craft, so be ready to do some exploring.
From there, you’ll need to collect ore, wood, and high-level trophies. You’ll complete dungeons, battle in World vs. World, collect karma, and visit theTempleofBalthazar. Once you collect all of the necessary gifts, materials, and karma, you’re ready to craft your Legendary Weapon.
