Iron Fortress
An iron fan made in the far west. Can be fit into the Shinobi Prosthetic to become a working Prosthetic Tool. Experienced iron-ribbed fan users can deflect arrows and even bullets using this tool. Passed down through generations of assassins serving Senpou Temple, it wouldn't be surprising if the next owner decided its weight was impractical.

Iron Fortress is special Upgrade Material in Sekiro: Shadows Die Twice. Iron Fortress unlocks the Loaded Umbrella prosthetic tool.

How to use Iron Fortress

• Bring it to the Sculptor at the Dilapidated Temple to unlock the Loaded Umbrella prosthetic tool.

Where to find Iron Fortress in Sekiro

Ashina Castle: The Iron Fortress tool is sold by the merchant Blackhat Badger for 1600 Sen. He is located inside a building near the Old Grave Idol in Ashina Castle (jump down the hole in the roof below the idol).

After you revisit Ashina castle for the second time and kill the boss?, if you have not purchased the tool beforehand it will be on the ground where the merchant originally was.

Iron Fortress Story & Lore

• The idea of utilizing this extraordinary device may have been derived from the DS Dark Hand, which manifests as a vortex-like shield, when it's left-handedly. Such vortexes represent The Abyss, at times rendered as a headpiece . The Darkness, which The Abyss represents, was often reputable for its heavy weight. Hats like these are called kasa and share their etymology with the Japanese word for "umbrella" (which is also pronounced "kasa", but written 傘). The fan's function as an umbrella (shadow) or parasol (sun ward) may explain its function annulling Darkness/Terror and Fire.
