These are the newest item collection from legendary weapon generation 3 available to you.
Legendary weapons are a set of high-end weapons that have unique appearances. They have the same stats as ascended weapons, but stat combo and sigils are not locked and can be freely changed when out of combat.
Legendary weapons are crafted in the Mystic Forge using a precursor weapon and the Gift of the Legendary Weapon associated with the desired end result, plus two other Gifts of Fortune and Mastery shared by other weapons of the same generation. Weapons of the first generation, released at the launch of Guild Wars 2, use Gift of Fortune and Gift of Mastery in their recipes, and Legendary Weapon Generation 2 released during updates following Heart of Thorns, use Mystic Tribute and Gift of Maguuma Mastery, or Gift of Desert Mastery. Legendary Weapon Generation 3 have two unique “features” not shared with previous generations: 1) They have a special “kill effect” that sometimes triggers upon defeating an enemy, and 2) They have secondary, unlockable skins themed for the elder dragons.
