- The Black Fox Mask is a head armor piece with lightweight stats and Onmyo-oriented bonuses.
In Nioh 3, hidden armor pieces often reward players who explore hub areas carefully. The Black Fox Mask is one of those secrets.

If you enjoy uncovering hidden paths and cosmetic lore pieces, this one is worth the effort.
Nioh 3 Black Fox Mask details
| Category | Details |
|---|---|
| Item Type | Head Armor |
| Weight | 0.8 (Lightweight) |
| Base Defense (approx.) | Scales with level; ~90+ at Lv.60+ |
| Key Bonus | Damage Bonus (Onmyo Magic) |
| Unlock Requirement | Defeat Takoda Shingun |
| Location | Hidden cave in Eternal Rift (via Spirit Vein) |
| Guardian Spirit Required | Kongo Jishi |
The mask is both cosmetic and functional. It carries light armor classification, meaning it fits best into agility-focused or ninja-style builds. Based on player reports and footage analysis, it frequently rolls Onmyo Magic scaling bonuses, along with situational Ki or Spirit Force modifiers.
Defeating Takoda Shingun to unlock Kongo Jishi
Before the mask becomes accessible, you must first defeat Takoda Shingun, a mandatory boss tied to unlocking the Guardian Spirit Kongo Jishi. Without Kongo Jishi unlocked, the hidden Spirit Vein that leads to the mask does not activate.

Takoda Shingun is designed as a mid-to-late progression boss encounter. Community discussions note that he combines heavy melee pressure with Guardian Spirit-enhanced bursts, forcing careful Ki management. Most successful strategies involve maintaining mid-range spacing and punishing after his heavy combo finishers. Once defeated, you unlock Kongo Jishi, which appears to act as a progression flag for the Eternal Rift secret.
| Boss | Unlocks | Requirement |
|---|---|---|
| Takoda Shingun | Guardian Spirit: Kongo Jishi | Story progression battle |
Unlocking Kongo Jishi is essential. If you attempt to locate the Spirit Vein before defeating Shingun, it will not be interactable.

After unlocking Kongo Jishi, travel to the Eternal Rift hub and locate the blacksmith area. The key to this secret lies in a basement section beneath the main forge level.

The Spirit Vein appears as a crystal-like rock formation embedded in the environment, subtly glowing compared to surrounding textures. Players often miss it because it blends into the stone walls unless viewed from an angle. Community footage shows that interacting with the vein triggers a transition animation.
How to reach the location of Black Fox Mask
Step 1
Travel to Eternal Rift and enter the blacksmith structure. From the main forge floor, locate the stairway or access path leading down into the basement level.
Step 2
In the basement, carefully scan the walls for a glowing crystal formation resembling a Spirit Vein. This is not marked on the map and does not display obvious prompts until approached closely.

Step 3
Interact with the Spirit Vein. If you have already unlocked Kongo Jishi, the vein will activate and allow passage.
Step 4
You will drop down into a dark hidden cave area. This section contains environmental roots and uneven terrain rather than enemies.

Step 5
Navigate across interwoven tree roots acting as natural platforms. Move cautiously, as falling can force you to restart the descent.
Step 6
At the end of the root pathway, locate a treasure chest. Open it to obtain the Black Fox Mask.

The platforming section is brief but requires controlled movement. Many players recommend lowering movement sensitivity temporarily to avoid slipping.
Black Fox Mask stats and effects
Based on high-level footage and equipment screens, the mask typically displays stats similar to the following when found around level 60+:
| Stat Category | Approximate Value |
|---|---|
| Base Defense | 90–95 range (level dependent) |
| Weight | 0.8 |
| Toughness | Low to moderate |
| Damage Bonus | Onmyo Magic scaling (C-grade) |
| Additional Rolls | Ki consumption reduction or Spirit Force charge bonuses |
The mask leans toward magic-focused hybrid builds, particularly those blending Onmyo and light armor mobility. Because it remains lightweight, it helps maintain A or B agility ratings, which many ninja-style players prioritize.
Lore and thematic significance
The in-game description references traditional Noh theater and festivals. The Black Fox is described as a mythical entity associated with peace and celestial symbolism, including ties to the Big Dipper. This aligns with Nioh’s broader integration of Japanese folklore into gear design.

Cosmetically, the mask features dark lacquered plating with glowing red accents in the eyes, making it one of the more visually striking headpieces in the current build. Players often use it in fashion builds or screenshot-focused loadouts.
Unlike boss drops or mission rewards, the Black Fox Mask requires environmental discovery. Community tracking suggests many players overlook it entirely unless guided.
Key reasons it’s missed include:
| Reason | Explanation |
|---|---|
| Hidden behind Spirit Vein | Requires prior progression flag |
| Located in hub area | Players rarely explore basements thoroughly |
| No quest marker | Entirely discovery-based |
| No combat trigger | Pure exploration reward |
Because of this design, the mask functions as a reward for attentive exploration rather than combat mastery alone.
Build synergy and practical use
If you focus on Onmyo Magic scaling, the mask provides meaningful early synergy. Combined with light chest and arm pieces, you can maintain low equipment weight while benefiting from magic-based damage boosts.

Players running hybrid ninja-Onmyo builds particularly benefit from its stat alignment. However, heavy armor users may find the defense tradeoff less appealing.
Using the Black Fox Mask
The Black Fox Mask in Nioh 3 is a perfect example of how the game rewards exploration beyond combat. By defeating Takoda Shingun, unlocking Kongo Jishi, and discovering the hidden Spirit Vein beneath the Eternal Rift blacksmith, you gain access to a stylish and lightweight headpiece that supports magic-focused builds. If you enjoy uncovering secrets and optimizing hybrid loadouts, this hidden cave is absolutely worth visiting.
