When it comes to weapon variety, Assassin's Creed Shadows does not disappoint. There are a ton of weapons for both Naoe and Yasuke that can do a lot of damage on the battlefield, especially if you're against higher-level enemies in the late game. Myth Slayer is one of the legendary long katanas that players can unlock for Yasuke during one of the main quests. It's a pretty solid weapon that comes with a unique perk that can help make enemies vulnerable a lot easier.
