Where to Find Achilles Helmet in Assassin's Creed Odyssey
Assassin's Creed Odyssey has 12 Legendary Armor Sets. This page contains a showcase of all armors with pictures and a guide for all legendary armor set locations.
Legendary Armor is the best in the game. It's colored yellow (or gold) in the inventory. What makes the sets special is that you gain an extra bonus for equipping the complete set. They also look fashionable when completed. The main ways you get these is from defeating all Cultists, Mercenaries, Arena, and some are from Legendary Chests.
