Onimusha Way of the Sword Weapons Tier List: All 7 Oni Armaments Ranked (2026)
Updated 2026-09-23 - 10 min read
Every Oni Armament Ranked
Quick answer: Way of the Sword gives you one katana - every other sword is a cosmetic skin. Real build variety comes from the 7 Oni Armaments (Two Celestials, Oni Bow, Wind-Whipper, Earth-Shakers, Firebird Flute, Flashing Void, Still Water) plus the unlockable Bishamon Sword.
Onimusha: Way of the Sword looks like a multi-weapon action game, but it is not: Musashi fights with a single katana from start to finish, and the swords you unlock only change its appearance. What actually changes your build is the Oni Armament system - seven supernatural tools, each with its own element, moveset and use case. This tier list ranks all seven, then covers the Bishamon Sword and every katana skin.
Rankings reflect how each Armament performs across the full game, from the Kyoto streets to Carnage mode. Your playstyle matters, but S-tier picks trivialize encounters that B-tier picks barely help with.
Weapon Tier List
| Tier | Oni Armament | Why |
|---|---|---|
| S | Earth-Shakers, Still Water, Flashing Void | Boss-killer, sustain/burst engine, single-target nuke |
| A | Wind-Whipper, Firebird Flute | Excellent crowd control and elemental utility |
| B | Two Celestials | Early sustain, outclassed once you have S-tier tools |
| Utility | Oni Bow | Free ranged attacks and seal-breaking; not a damage tool |
Collecting all 7 Oni Armaments unlocks the Oni Armory trophy / achievement.
S-Tier Armaments
Earth-Shakers (Gauntlets)
The best Armament in the game. These stone gauntlets shred enemy stamina and armor, stagger elite enemies out of their guard, and chew through boss health bars faster than anything else. If you only master one Armament, make it this one.
- Location: Underground laboratory - open the treasure chest behind the fan mechanism
- Best for: Bosses, armored enemies, guard-breaking
- Strengths: Highest damage output, breaks armor and stamina
- Weaknesses: Short range; you must commit to melee
Still Water
A water Armament found in the Arashiyama swamp that supercharges your Awakening gauge. More purple soul charge means more time in powered-up state, which means more damage and more survivability in long fights. The engine behind every high-level build.
- Location: Arashiyama swamp treasure
- Best for: Sustain fights, Awakening-focused builds
- Strengths: Faster Awakening charge, strong water damage
- Weaknesses: Requires soul management to shine
Flashing Void
A lightning lance from Mount Oe with the highest single-target burst in the game. Wind it up on a stunned or slowed boss and watch the health bar disappear. Less flexible than Earth-Shakers, but the best pure nuke.
- Location: Mount Oe treasure #4
- Best for: Single-target burst, punishing openings
- Strengths: Huge lightning damage on one target
- Weaknesses: Situational; needs a safe window to use
A-Tier Armaments
Wind-Whipper
A wind flail you receive through the story. Its whirlwind attacks control crowds beautifully, knock groups of enemies back, and can ignite enemies near open flames. Not a boss-killer, but it makes mob fights trivial.
- Location: Story reward (cannot be missed)
- Best for: Crowd control, fighting groups
- Strengths: Wide whirlwind hits, fire synergy
- Weaknesses: Mediocre against single tough enemies
Firebird Flute
A fire Armament hidden at Tokyo Toho building #45. Its bird-shaped flames burn and stun up to three enemies at once, making it the best lockdown tool for elite packs and a strong combo starter.
- Location: Tokyo Toho #45 treasure
- Best for: Locking down elite groups, fire combos
- Strengths: Burns and stuns multiple targets
- Weaknesses: Fire-resistant enemies shrug it off
B-Tier & Utility
Two Celestials (B-Tier)
The first Armament most players find - it sits in the game's first treasure chest. It converts yellow souls into health, which is great sustain in the early hours but falls off hard once Earth-Shakers and Still Water come online. Keep it as a healing battery, not a damage tool.
- Location: First treasure chest in the game
- Best for: Early-game sustain, soul-to-HP conversion
- Strengths: Free healing, available immediately
- Weaknesses: Low damage, replaced quickly
Oni Bow (Utility)
Found at the Oni Refuge, the Oni Bow fires without consuming Oni Power. Its damage is modest, but it is the only free ranged option in the game and - more importantly - the tool for shooting seals and distant switches. You will use it constantly without ever building around it.
- Location: Oni Refuge
- Best for: Free ranged pokes, breaking seals, switches
- Strengths: Costs no Oni Power, essential for puzzles
- Weaknesses: Low damage, no melee use
The Bishamon Sword: The Ultimate Unlock
The Bishamon Sword is the only weapon that changes how the katana itself performs, and it is earned, not found. The unlock chain is a nod to the original Onimusha: Warlords, where the Bishamon Ocarina hid on floor 20 of the Dark Realm:
- Clear the game once to unlock Carnage mode
- Clear Carnage mode
- Equip the Spirit Mirror - the sword then becomes usable
The payoff: roughly 10% more damage plus a wider parry and Issen timing window. On a game built around deflect timing, that wider window is the real prize - it makes high-level play noticeably more forgiving. Pair it with the Earth-Shakers and nothing in the game survives long.
