What Are Oni Armaments in Onimusha: Way of the Sword?

Oni Armaments in Onimusha: Way of the Sword are special weapons forged by the Oni and summoned using Musashi’s Oni Power. They are not regular weapons that you permanently equip or switch between during normal combos. Instead, they provide powerful special attacks during combat.

There are seven Oni Armaments to find across specific locations on the map. Each one has a unique attack that can deal more damage than standard swordplay and can also generate extra souls, especially yellow souls that restore health.

You can activate an available Oni Armament when the Oni Power gauge is fully charged. Using an Oni Armament consumes the gauge, which must be refilled by absorbing Blue Souls during combat. And most importantly, collecting all seven Oni Armaments unlocks the Oni Armory trophy and achievement.

How Oni Armaments Work

Before looking for all the Oni Armaments in Onimusha: Way of the Sword, it is better to understand how they work during gameplay.

  • Activating Oni Armaments: You can activate an available Oni Armament when the Oni Power gauge is full. Activating one completely drains the gauge and lets you use its special attacks for a short time.

  • Filling the Oni Power Gauge: The gauge is filled by absorbing Blue Souls from defeated enemies. Hold the absorb button while moving near the souls to collect them.

  • Upgrading Oni Armaments: Some Oni Armaments can be charged or upgraded using Red Souls or Oni Stones through the Spirit Mirror or skill menus.

With these details in mind, let’s discuss all Oni Armament locations and how to get them to help you find them during your gameplay.

The Two Celestials

The Two Celestials are the first Oni Armament you can obtain. This is  a pair of deadly dual blades that unleash rapid flurries of attacks.

The Two Celestials

How to get The Two Celestials in Onimusha: Way of the Sword:

You can find them while completing the Main Mission :"The stage is set at Kiyamizu" through Kiyomizu-dera Temple. Then defeat the second Thread Genma locking the Oni Gate. After defeating it, the treasure chest suspended by the red vines drops down. Open the chest to obtain The Two Celestials.

Effects: Unleashes a string of special attacks that extract yellow souls from enemies, which are useful for healing.

Best Uses: Useful when your health is low, against single enemies or small groups, and during fights where you need to recover health while attacking.

Oni Bow

The Oni Bow is a powerful ranged Armament that lets Musashi fire arrows at distant or elevated targets. It is a part of the main story and essential for certain story and boss interactions.

Oni Bow

This can be found in a chest on the main path while heading to the Oni Refuge. Because the bow is required for story progression, you do not need to worry about permanently missing it.

Effects: Allows Musashi to fire ranged arrows and target specific areas, including charged shots that deal more damage.

Best Uses: Great for attacking specific target areas and dealing safe damage from a distance.

Wind-Whipper

Wind-Whipper is one of the best Oni Armaments for dealing with groups of enemies. It is a double-bladed naginata that Musashi spins overhead to create a wide whirlwind. This is also a part of the main story which can be unlocked through your progress.

Wind-Whipper

How to get Wind-Whipper in Onimusha: Way of the Sword:

Automatically obtained during “The Oni’s Apprentice” mission. During this mission, Musashi is taken to the Practice Ground. After the game introduces the Skills practice area and Boss Rematch features, a chest appears containing the Wind-Whipper.

Effects: Area-of-effect whirlwind that launches foes, negates projectiles, and becomes a fire cyclone near flames.

Best Uses: Great for fighting groups, dealing with enemies surrounding you, attacking archers, and clearing open areas.

Earth-Shakers

The Earth-Shakers are massive hammers that deal heavy damage and quickly break enemy stamina, shields, and armor. They also have charging attacks that makes them even more powerful for breaking the enemy defenses. And be careful, the Earth-Shakers are easier to miss than the story Armaments.

Earth-Shakers

Travel to the Underground Laboratory and reach Underground Level 4. Progress through the area until you complete the fan puzzle. After the puzzle, enter the next room and look for the treasure chest containing the Earth-Shakers.

Effects: Heavy strikes that rapidly deplete stamina bars, break shields, and destroy armor. Charged attacks deal even more damage.

Best uses: Best against the armored or shielded enemies, bosses, and other heavily defended targets. They can quickly reduce a boss’s stamina with a single strong hit, making them one of the best Oni Armaments in the game.

Still Water 

Still Water is the final Oni Armament to collect. It is a sword-type Armament that unleashes a powerful shockwave against enemies.
