Onimusha: Way of the Sword Weapons Tier List

Quick Answer: What Is the Best Weapon in the Game?

Direct Answer: The undisputed best weapon in Onimusha: Way of the Sword is the Bishamonten Sword (毘沙门宝剑) (S+ Tier), obtained by conquering Floor 20 of the Dark Realm. It deals the highest base slash damage and cleaves standard Genma in a single strike. For the main campaign progression, Raizan - Thunder Katana (雷斩刀) (S Tier) is the most versatile blade due to its rapid lightning weapon art, superior boss parry stuns, and high single-target burst damage.
