In the thrilling world of Ninja Gaiden 4, players are met with an epic finale where Yakumo gains an edge with the Dark Dragon Blade. This weapon, pivotal for defeating the final boss, can be permanently unlocked in a remarkably short span. Here’s how you can achieve this feat in under 30 minutes.
Unlocking the Powerful Dark Dragon Blade
To secure the Dark Dragon Blade for Yakumo, players must first conquer the Dark Dragon in Chapter 19. This will unlock the Boss Trial challenges, which upon completion, permanently unlock the blade for use in various game modes.
Speeding Through Boss Trials

Defeating all 13 bosses from the main campaign can be daunting, but there’s a method to make it swifter. Leveraging the Hero Difficulty setting, players can enhance damage output and reduce boss health, simplifying the challenge.
1. **Pre-Boss Difficulty Switch:** Before starting a Boss Trial, toggle to Hero difficulty by pressing R1/Right Button. Activate Auto-Dodge and Auto-Assist for seamless combat.
2. **Maximize Damage:** Utilize the Senjin War Brew during trials to boost damage. Reuse as needed.
3. **Pick the Best Weapon:** At the trial’s onset, select the Kage-Hiruko weapon for its ranged capabilities, ensuring continued attacks even at a distance.
With this strategy, completing all trials took just 23 minutes and 4.412 seconds. Including setup time, the entire process should take less than half an hour, granting permanent access to the Dark Dragon Blade.
