Step-by-Step Area Clearance & Item Pick-Up Order

Step 1: Return to Ashina Castle — Shinobi Siege Active

Area Clearance Order: After collecting all three ritual items (Mortal Blade, Lotus, Shelter Stone), all Ashina Castle Idols (except the Dungeon Entrance) will become locked due to a Shinobi invasion. Fast travel to the Abandoned Dungeon Entrance Idol. Grapple up the bottomless pit and make your way back into Ashina Castle. The castle is now flooded with purple Ministry ninjas fighting the Ashina elite. Proceed cautiously through the grounds.

Step 2: Ashina Dojo — Mini-Boss Lone Shadow Vilehand

Area Clearance Order: Grapple along the castle rooftops following the same path as before to re-enter the Upper Tower Antechamber. Stealth past the battling samurais and ninjas, and ascend the stairs toward the Ashina Dojo. Do not rush into the room! A purple ninja is waiting in the corner. Sneak in, backstab him, and use the Puppeteer Ninjutsu to make him fight Lone Shadow Vilehand for you. Use Mikiri Counter on Vilehand's kicks and defeat him to claim Prayer Bead #29.

TACTICS WARNING: Click to Reveal Detailed Puppeteer 2v1 & Poison Leg Counter Strategy

Detailed Dojo Tactics & Puppeteer Setup:

  • Puppeteer Ninjutsu 2v1: Consume a Gachiin's Sugar before entering the room door. Crouch-walk along the left wall behind the secondary ninja standing next to Vilehand. Backstab him and activate Puppeteer Ninjutsu to turn him into a temporary ally who fights Vilehand 2v1!
  • Poison Kick Mikiri: Vilehand uses poison leg strikes. Deflect his 4-kick combo and execute a Mikiri Counter on his perilous kick thrust.

Items to Keep Picking Up:

  • Prayer Bead #29 — Dropped upon defeating Vilehand.
Step 3: Serpent Shrine — Mini-Boss Lone Shadow Masanaga

Area Clearance Order: Head back to the Old Grave Idol and make your way down the forest path behind the castle towards the Great Serpent Shrine. Here you'll find Lone Shadow Masanaga the Spear-Bearer mourning. Drop onto him from the roof for a stealth Deathblow. Keep pressure on him and throw Shurikens to interrupt him whenever he tries to whistle for his poison dogs. Defeating him rewards Prayer Bead #30.

TACTICS WARNING: Click to Reveal Detailed Shuriken Dog Interruption & Stealth Opener

Detailed Shrine Combat:

  • Stealth Plunge Opener: Approach from the roof of Great Serpent Shrine building. Drop down onto Masanaga while he is praying for a free 1st health bar Deathblow!
  • Dog Whistle Shuriken Interrupt: Whenever Masanaga steps back to blow his whistle to summon poison dogs, throw a Loaded Shuriken immediately to hit him in mid-whistle and cancel the dog summon.

Items to Keep Picking Up:

  • Prayer Bead #30 — Dropped upon defeating Masanaga.
Step 4: Castle Lobby — Chained Ogre Rematch

Area Clearance Order: Return to the Upper Tower Antechamber. Instead of going to the Dojo, look down into the ground floor lobby where a Chained Ogre has broken loose and is fighting Ashina guards. Drop down onto the wooden crossbeam, lock on, and deliver a plunging stealth Deathblow to the Ogre. Then use Flame Vent to burn away his remaining health. He drops Prayer Bead #28 and the Shinobi Medicine Rank 3 passive skill.

TACTICS WARNING: Click to Reveal Rafter Stealth Plunge & Flame Vent Strategy

Rafter Plunge & Fire Burn: Stand on the upper interior beam overlooking the ground floor lobby. Drop down directly onto the Ogre for a free stealth Deathblow! Throw Oil + Flame Vent to incinerate his remaining health bar.

Items to Keep Picking Up:

  • Prayer Bead #28 — Dropped upon defeating Chained Ogre.

CRITICAL WARNING: Can You Cancel Owl's Dialogue? (Point of No Return)

NO — You CANNOT cancel or exit Owl's dialogue once started!

When you walk up to Great Shinobi Owl on the rooftop and press the interact button to speak with him, you are locked in. When the menu pops up asking you to choose between Obeying the Iron Code or Breaking it, there is NO "back" button or "let me think about it" option. You must choose one immediately.

When & How to Make Your Manual Save (All 4 Endings in 1 Playthrough)

Rest at Upper Tower — Ashina Dojo idol (right below roof). Step onto roof, see Owl, but DO NOT WALK UP TO HIM OR TALK TO HIM YET. Exit to main menu and copy your save file (%AppData%\Sekiro\<SteamID>\S0000.sl2)!

Before choosing your path, review the dedicated guides and step-by-step walkthrough parts for every specific ending route:

Step 5: Castle Rooftop — Main Boss Great Shinobi Owl

Area Clearance Order: Ascend out of the Dojo window to the snowy rooftop. You will find Great Shinobi Owl waiting for you. This is the crucial story branch. Choose "Break the Iron Code, Stay Loyal to Kuro" to face him in battle. Owl fights similarly to you, utilizing firecrackers, shurikens, and anti-healing bombs. Defeat him to claim the Memory: Great Shinobi Owl and the Aromatic Branch, completing the three required ritual items.

TACTICS WARNING: Click to Reveal Detailed Anti-Heal Bomb Dash & Front-Flip Slam Punish

Detailed Shinobi Master Strategy:

  • DO NOT use Thrust Attacks: Owl knows Mikiri Counter! If you press & hold R1 to thrust, he will stomp your blade and instantly kill you. Stick to normal slashes.
  • Anti-Heal Bomb Punishment: When Owl throws a green orb charm that disables healing, dash forward-right past his left shoulder. You will step around the green cloud and land 2 free slashes on his back!
  • Shuriken Double Flip Slam: Deflect his 2 shurikens, then dodge sideways as he executes his high front-flip sword slam. Punish his landing with Mortal Draw or Ichimonji: Double.
  • Phase 2 Smoke & Poison: In Phase 2, dodge away when he throws smoke bombs to reset camera lock, and step out of poison pools.
MAJOR STORY SPOILER: Click to Reveal Shura vs Immortal Severance Choice

Shura Ending: Choosing "Obey the Iron Code" triggers fights against Emma & Isshin Ashina, concluding the game early with the evil Shura ending. Staying loyal to Kuro opens Fountainhead Palace!

Items to Keep Picking Up:

  • Memory: Great Shinobi Owl — Consume at Idol for +1 Attack Power!
  • Aromatic Branch (Key Item) — Dropped upon defeating Owl.

Next Steps: What You Should Do Now

The Shinobi Siege has concluded, and depending on your choice, you are either locked into the Shura ending or moving forward to Fountainhead Palace. If you stayed loyal to Kuro, head to the Wedding Cave Door in Ashina Depths to enter the Palanquin.
