Introduction
Sekiro: Shadows Die Twice is known for its punishing difficulty, and Isshin, the Sword Saint, stands as one of the toughest bosses in the game. Most players rely on precise swordplay and deflection to defeat him, but what if there was a way to obliterate him in just 45 seconds without ever using your katana?
In this guide, we’ll break down the ultimate Shinobi Tool strategy that allows you to annihilate Isshin with brutal efficiency—no sword required!
The Strategy Overview
The core of this method revolves around prosthetic tools, combat arts, and posture-breaking tactics that exploit Isshin’s weaknesses. Here’s the breakdown:
Required Tools & Skills:
- Loaded Spear (Spiral Spear) – For posture damage and follow-up attacks.
- Firecrackers (Purple Fume Spark) – Stun-lock Isshin for free hits.
- Mortal Draw (Combat Art) – Devastating damage without needing a sword.
- Ako’s Sugar/Spiritfall – Boosts damage output.
- Gokan’s Sugar/Spiritfall (Optional) – Reduces posture damage taken.
Phase Breakdown:
Phase 1: Lightning-Fast Aggression
- Open with Firecrackers – Stun Isshin immediately.
- Mortal Draw (Uncharged) – Deal massive vitality damage.
- Spiral Spear Thrust – Follow up with posture-breaking attacks.
- Repeat – Stun-lock him before he recovers.
Phase 2: Exploiting His Moveset
- When Isshin pulls out his spear, dodge backward and bait his leaping slash.
- Firecrackers + Mortal Draw – Punish him mid-animation.
- Spiral Spear Combo – Keep his posture from recovering.
Phase 3: The Final Blow
- If he uses Lightning Reversal, let him—it’s a free counter.
- Firecrackers + Mortal Draw – Finish him before he can react.
Why This Method Works
1. Posture Destruction
Isshin’s posture recovers quickly, but Spiral Spear’s thrust + pull combo deals massive posture damage, especially when combined with Mortal Draw.
2. Stun-Locking with Firecrackers
Firecrackers interrupt his attacks, allowing free Mortal Draw hits without retaliation.

3. No Sword, No Problem
Mortal Draw doesn’t require a sword, making it perfect for this challenge. The spear’s range also keeps you safe from counters.
Execution Tips
- Stay Aggressive – Hesitation is defeat. Keep pressure on Isshin.
- Manage Spirit Emblems – Use Ako’s Spiritfall if emblems run low.
- Perfect Dodges – If Firecrackers miss, dodge his spear sweeps.
Conclusion
With this ultimate Shinobi Tool loadout, Isshin falls in under 45 seconds without a single sword swing. This method proves that Sekiro’s prosthetic tools are overpowered when used correctly.
Try it out and dominate the Sword Saint like a true Shinobi!
