Master Sekiro's Prosthetic Tools! Learn all upgrade paths, find the best upgrades, and discover how to acquire essential materials like the Mechanical Barrel.

Hey there, Shinobi! Ready to really soup up your arm? This guide's gonna walk you through all the Prosthetic Tool upgrade paths in Sekiro: Shadows Die Twice. We'll cover what you need, where to find it, and which upgrades are worth your precious Sen and Crafting Materials. ### Unlocking Prosthetic Tool Upgrades Before you can even think about upgrading, you'll need to get the ball rolling with the Mechanical Barrel. This special item is your key to unlocking the entire Prosthetic Tool Upgrade tree. * What it is: A mechanical metal barrel designed to fit into the Shinobi Prosthetic. * Where to get it: You'll earn the Mechanical Barrel by defeating Gyoubu Oniwa in Ashina Outskirts. Make sure you grab it when he falls! * What to do with it: Take it to the Sculptor at the Dilapidated Temple. Handing this over will unlock the Prosthetic Tool Upgrades. Important Note: You can only carry one Mechanical Barrel at a time. If you somehow miss it after defeating Gyoubu Oniwa, you're out of luck for that playthrough, as it's a unique item. ### Prosthetic Tool Upgrade Materials Upgrading your tools requires a variety of materials. You'll be hunting for things like: * Adamantite Scrap * Black Gunpowder * Flame Barrel * Fulminated Mercury * Gyoubu's Broken Horn * Lapis Lazuli * Large Fan * Lump of Fat Wax * Lump of Grave Wax * Malcontent's Ring * Mist Raven's Feathers * Phantom Kunai * Pine Resin Ember * Poise * Prayer Beads * Robert's Firecrackers * Sabimaru (Upgrade Material) * Scrap Iron * Scrap Magnetite * Shinobi Axe of the Monkey * Shuriken Wheel * Slender Finger * Yellow Gunpowder Keep an eye out for these as you explore and defeat tougher enemies. Many of them are dropped by specific mini-bosses or found in certain areas. ### Which Upgrades Are Best? While the "best" upgrade often depends on your playstyle, some tools offer significant advantages early on or have universally useful upgrades. * Shuriken Wheel: Some players consider this the best prosthetic tool because it's available early and has some very useful upgrades that can help with crowd control and interrupting enemy attacks. * Flame Vent: Upgrades to the Flame Vent can deal significant damage and inflict Burn, which is great against certain enemies and bosses. * Sabimaru: While it has a unique upgrade path, Sabimaru's poison effect can be incredibly potent against many foes. We'll dive into the specific upgrade paths for each tool in more detail soon. For now, focus on getting that Mechanical Barrel and start gathering those materials!
