Shuten Doji looks like a pushover for about ninety seconds. He swings a sword, you deflect, you chip his health, and then he stops mid-fight to swig from a gourd and undo your work. That’s the easy part. The moment Musashi takes his head off, the fight doubles in size and the arena catches fire.
Quick answer: Stop Shuten Doji from drinking his gourd in phase one, then in phase two shoot his floating head with your bow the instant the game warns you he’s about to breathe fire, spam Reflex Dodge with the left stick whenever you catch Burning, and cash in the Onimusha Awakening the fight hands you for a burst of Issen strikes before it expires.
Before you start The Demon on the Mount
The encounter is labelled “The Demon on the Mount” with the objective “Defeat Shuten Doji,” and it takes place in the fortress atop Mount Oe. One detail matters more than any loadout choice here: the game does not refund your Hozuki Pouch charges when you cross into phase two. Burn all your healing on the humanoid form and you will start the hard half of the fight with an empty pouch.
So treat phase one as a resource test, not a damage race. Take the free openings, eat as little damage as possible, and hold at least a couple of charges in reserve.
Note: bosses in Way of the Sword react to how badly you’re playing. Take heavy damage early and they slip into their enhanced state sooner than they otherwise would, which makes a sloppy phase one bleed directly into a harder phase two.
Phase 1: The Gourd Drainer and his healing sips
Shuten Doji opens the fight in a humanoid form tagged “Gourd Drainer,” and the name is the whole mechanic. He fights with broad, readable sword swings inside the temple hall, and he is comfortable to defend against — parry or deflect the swings, punish the recovery, repeat. His stamina drains from deflects roughly twice as fast as it does from raw strikes, so blocking well is the fastest route to a stance break.
The catch is the gourd. Periodically he backs off and drinks, restoring health and erasing whatever progress you made. Watch for the wind-up, close the gap, and pressure him out of it. Every sip you allow is a chunk of the health bar you have to grind through twice.
When his health runs out, a cutscene plays: Musashi decapitates him. It is not a kill. The severed head lifts off as a burning skull while the body ignites, and both halves come after you.
Phase 2: Fighting the flaming body and the floating head
You are now managing two threats at once. The body is a flaming giant that slams the ground and swings heavy; the detached head hovers and lobs fireballs from wherever it feels like. Most deaths here come from tunnel-visioning on the body while the head sets the floor on fire behind you.
| Attack | What to do |
|---|---|
| Fire breath from the floating head | The game flashes a warning to stop him before he breathes. Draw your bow and shoot the head to cancel it outright. |
| Ground slams that raise pillars of fire | Block the heavy slam itself, then move off the pillar’s footprint immediately rather than standing to counter. |
| Fireballs launched by the head | Keep the camera loose and dodge laterally. Do not try to trade damage through them. |
| Large area-of-effect fire blast | The one-shot risk of the phase. Create distance the moment the flames start pooling around him. |
| Standard heavy swings | Deflect and counter. Landing an Issen here is worth far more than a safe combo. |
The bow shot on the head is the single most valuable input in the fight. Fire breath is the attack most likely to catch you mid-animation, and cancelling it costs you almost nothing.
Reflex Dodging and clearing the Burning status
Two prompts appear during this fight, and both are worth internalising. Reflex Dodging triggers when you press B just before a hit lands, which is the safest answer to anything you can’t read cleanly. Against a boss this fast and this wide, dodging is a perfectly acceptable default when your deflect timing isn’t there.
The second is fire. Once you catch Burning, you keep losing health until you shake it off, and the fix is to evade repeatedly with the left stick. Do it straight away — do not try to squeeze in one more attack first. Burning plus an incoming slam is how most phase two runs end.
Use the Onimusha Awakening the fight gives you
This encounter unlocks Musashi’s Awakened Onimusha form, and the game tells you outright that the power will not last forever. Treat it as a timer, not a safety net. Once you transform, Issen strikes become dramatically easier to land, so use the window to chain them rather than mashing the finisher immediately. Save the big finishing input for the moment the meter is nearly gone.
Outside of Awakening, the loop is the same as every other boss in the game. Deflect or counter with Issen, drain the stamina bar, siphon the souls, and go again.
If you die, you restart from phase 2
Dying here is cheap. The “You have fallen” screen puts you into a menu with several options, and Retry drops you back at the start of phase two rather than making you refight the Gourd Drainer. That makes learning the fire patterns far less painful than it first looks.
| Menu option | What it does |
|---|---|
| Retry | Restarts the encounter at phase two. |
| Enhance Skills and Equipment | Spend resources on upgrades before retrying. |
| Storehouse | Access stored items. |
| Change Hozuki Pouch | Swap your healing loadout. |
| Replay from Last Save | Reloads your last save instead of the checkpoint. |
| Change Difficulty | Drops the fight down if you’re stuck. |
How you know the fight is over
The final blow makes Shuten Doji’s flaming form disintegrate rather than simply collapse, and control passes straight to a cutscene in the ruined temple with Musashi, Shizuka and Okuni. There is no ambiguity and no third phase waiting behind it.
Clearing it also moves the story forward in a concrete way. Shizuka commits to travelling with Musashi from here, and the scene closes at camp with him laying out his own blunt reading of the way of the sword — that it’s a contest of strength, and whoever wins is the strongest. Whether he’s right is a question the rest of the game keeps asking.
