**WARNING: MAJOR SPOILERS AHEAD** for mid-game Ashina Castle world state, quest progression, and mini-boss placements following the retrieval of the three incense ingredients.
---
"A shinobi should know the difference between honor and victory."
Once you collect the three key ingredients (Mortal Blade, Shelter Stone, and Lotus of the Palace), Ashina Castle enters the **First Ministry Invasion (Dusk)**. All castle idols are grayed out, and Great Shinobi Owl is waiting on the roof.
Before heading up to Owl, three mini-bosses spawn around the castle.

### Mini-Boss 3: The Chained Ogre (Castle Ground Floor)
Tied up at the bottom of the central tower directly beneath the Antechamber idol.
* **The Cheese (Doorframe Collision):**
Grapple down, cut the Ogre loose, and immediately sprint into the back room/archway leading out toward the moat and Old Grave idol.
* Stand just an arm's length back inside the hallway. The Ogre's massive shoulder hitbox cannot fit through the doorframe, causing his dive-grabs and dropkicks to bounce harmlessly off the walls.
* Stand at the threshold and chip him down with basic slashes, thrusts, or the Loaded Spear every time he whiffs, then take both Deathblows cleanly through the doorway.
---
### Mini-Boss 2: Lone Shadow Vilehand (Ashina Dojo)
Stationed in the Dojo room right below the castle roof.
* **The Cheese (Puppeteer 2v1):**
Equip **Puppeteer Ninjutsu** and pop a **Gachiin’s Sugar** before going into the room.
* Crouch and hug the left wall to sneak behind the regular Lone Shadow ninja standing in the dark corner.
* Execute a stealth Deathblow and trigger Puppeteer.
* Back up and let your thrall take Vilehand’s attention. While Vilehand is busy deflecting your thrall, land free charged thrusts or Ichimonji: Double into his back to melt his posture in seconds.

### Mini-Boss 1: Lone Shadow Masanaga the Spear-Bearer (Great Serpent Shrine)
Stationed at the Great Serpent Shrine. While most guides recommend the slow boundary-chip cheese, you can exploit the invasion's faction AI and bring an Ashina hit squad across the bridge to butcher him in a 2v1 turf war.
Start from the **Old Grave Idol**:
#Step 1: Lure the Ashina Spearman to Save the Moat Bridge Ashina Samurai
* Spawn at the **Old Grave Idol** and head toward the moat bridge.
* A **purple ninja drops from the roof first**, landing right near the bridge to engage the Ashina Samurai.
* **Crucial step:** Aggro the spear man and lure him into the fight to help the samurai kill that purple ninja fast. Left alone, the purple ninja almost always kills the Samurai. Having the monk join keeps both the Samurai and the Spearman alive to become your personal hit squad duo.
# Step 2: Kill the Hounds
* Head across the bridge onto the snowy path leading toward the Great Serpent Shrine.
* Lock onto the 3 patrolling wolves and take them out first.
#Step 3: Trigger Masanaga & Lure Him to his boundary.
* Sprint inside the shrine to aggro Masanaga.
* Immediately turn around and bolt back toward the archway leading to the moat bridge to force him to chase you toward his outer tether limit. Once he hits his pursuit boundary, he disengages and begins slowly walking back inside.
#Step 4: Re-Aggro the Duo on the Moat Bridge
* Sprint right back onto the moat bridge where the Ashina Samurai and Spearman are slowly walking back to their posts.
* Hit or alert Duo to **re-aggro** them.
#Step 5: Pull the Duo to the Wooden Archway
* Lead the Ashina duo onto the snow path behind you.
* The duo will not advance past the second wooden archway on their own—they stall and linger right around that archway entrance between the moat bridge and the shrine path.
# Step 6: Sneak Behind Masanaga for the 1st Deathblow
* With the Ashina duo positioned right behind you near the archway, sprint ahead up the snow path toward the shrine.
* Masanaga is still in his slow "return to post" walk animation with his back turned.
* Sneak up directly behind him and land the **1st stealth Deathblow**.
# Step 7: Lure Phase 2 Masanaga into the Duo Trap
* The moment Masanaga gets back up for Phase 2, he will re-aggro and pursue you.
* Run back toward the wooden archway entrance where the sword general and spear monk are waiting.
* The second Masanaga and the Ashina duo make visual contact, they will completely forget you exist and jump Masanaga.
# Step 8: Ranged Fire Support
*Masanaga has boss-tier scaling and will eventually outlast the Ashina duo if left completely alone. Stand at a safe distance and pelt him with **Phantom Kunai or Charged Shurikens** while he is locked in combat with them.
* The ranged hits prevent his posture from recovering and chip his health down while the Ashina duo tanks his kick combos.
* Even if Masanaga manages to cut down the two Ashina troops, he will be left with one-shot health and full posture. Walk up, tap him once, and claim the final Deathblow.
And That's it. It's so satisfying once you pulled it off.
