Excalibur Sword [AC: Valhalla]

Assassin's Creed: Valhalla's Excalibur is an exciting prospect - a chance to get your hands on perhaps Britain's most legendary sword.

Being a very difficult and obscure item to obtain, Excalibur doesn't have any sort of prompt or related questline - but you can start collecting the necessary items to obtain it as soon as you arrive in England.

However, is strongly advised to wait until the late game, since some of the required parts include three boss fights from high power level, making it extremely difficult if you're unprepared.
