Legendary Items include Legendary weapons and armor sets in Greedfall. These weapons and armor are the best and most powerful of the game. They deal high damage and provide great protection but as expected, are tough to get.
Legendary weapons and legendary armor sets in Greedfall are to either found in a hidden chest or after you have fought a boss. You might get a key for these hidden chests and then you can open them.
Light Flamberge Location
While Light Flamberge can be acquired early in the game, this is not an easy task. This one-handed blade is guarded by high level bandits preying the East Road of Whenshaganaw, “The Singing Waters”. After defeating them, look for a rock surrounded by bushes. Behind it you’ll find a dug hole with a chest that holds this treasure.
