Way of the Sword — Best Oni Armaments Tier List

Oni Armaments are Way of the Sword’s heavy-damage consumable weapons, fueled by blue souls absorbed through the Oni Gauntlet. They are one-shot panic buttons for tough fights, not permanent weapon slots. The strategic question is not “which armament does the most damage” but “which armament interrupts the encounter I’m stuck on.”

What Oni Armaments actually do

Unlike the katana (Musashi’s permanent weapon), Oni Armaments are consumables. You spend blue souls to activate them, they do a specific effect (usually heavy damage plus a stagger or interrupt), and then they’re gone. The cycle is:

1. Farm blue souls from regular Genma.
2. Spend them on an Oni Armament activation.
3. Use the armament’s effect to break a boss’s momentum or finish a tough enemy.

Tier list principles

The best armaments are not the ones with the highest damage number. They are the ones that:

• Interrupt unparryable attacks — boss moves that can’t be parried are the most common cause of wipes. An armament that creates an opening is worth more than one that does raw damage.
• Break stamina gauges fast — bosses with high stamina benefit from armaments that drain multiple bars at once.
• Cover multiple enemies — some armaments are AoE, which is huge when adds pile on during a boss fight.

Recommended usage

Top picks (to be expanded after verification)

These are the armaments Capcom has confirmed or strongly hinted at, ranked by their likely use cases once verified numbers are added:

S-tier (boss fight essentials)

• Heavy Blade-type armaments — designed to interrupt boss combos. Use these against enemies with unparryable attack chains.
• AoE blast-type armaments — break stamina gauges on multiple enemies at once. Strong against adds-heavy boss fights.

A-tier (specialized)

• Ranged thrust armaments — useful for ranged enemies that punish melee approaches.
• Fast activation armaments — low wind-up, good for panic-button usage.

B-tier (situational)

• High-damage single-target armaments — strong raw damage but no utility. Use these on boss phase transitions where you just need the kill.

Where to find them

• All seven locations: the locations guide maps every acquisition — story rewards and chests alike, cross-checked across three published guides.
• Soul farming: the soul farming guide covers the routes that keep the gauge full.
• Chests: five of the seven sit in optional chests you can return for at any time.
