Make your preparations at the Statue before heading to the boss arena! This is the final boss of the Main Story, so it will be a brutal fight.
[2] Defeat Hiruko-possessed Kunimatsu.
You've faced Hiruko before in "Dark Roots", but this time he is more powerful and brings a completely different moveset.
・Fortunately, this is a single-phase fight. You only need to deplete his single health bar to win.
・Like every other boss you've faced, he'll become more aggressive once his HP is significantly reduced. Keep your guard up during the latter half of the battle.
・Hiruko can also transport you to the Dark Realm; focus on breaking his Ki when this happens.
| Move | Showcase | Details |
|---|---|---|
| Fire Skills |    | Most of his attacks for the early stage will be Fire-based. Watch out for these Moves: ・Hiruko creates a ring of fire that spreads across the arena. Time your jump to avoid this. ・He plunges his weapon into the ground before circling and launching multiple lava projectiles. ・In the Dark Realm, expect Fire Tornadoes and Fire Trails directed at you. ・He can also lift his sword to create a huge orb that will trigger a fiery explosion. |
| Bloody Rain |  | This is a familiar move for Hiruko. Remember to stay outside the range of this attack. |
| Guardian Spirit Summon |  | The Boss can summons his Guardian Spirits. Keep a close eye on his summons' attacks! You can also counter them by calling for help yourself. |
| Ice/Lightning Skills |   | As the fight gets more intense, Hiruko will start to use Ice/Lightning Skills. Pay close attention to visual cues so you can perfectly time your dodges. |
| Piercing Spikes |  | When you see spiky thorns appear on his weapon, back away quickly! He is about to perform a large AoE attack. |
[3] Continue What Makes A Shogun.
After completing the battle, continue the second part of the "What Makes A Shogun" Quest to finally reach the ending of Nioh 3!
