Below we have detailed how you can upgrade the Prosthetic Tool and what materials you require in order to upgrade.

How to Unlock Prosthetic Tools Upgrades

The firs thing required to apply any upgrade to the Prosthetic Tools, you need to get the Mechanical Barrel. This can be taken after you defeat the first boss of the game.

The first boss is Gyoubu Masataka Oniwa, and he can be found in the Ashina Outskirts, in the Ashina Castle Gate Fortress idol. The fight can be tough, but you can defeat this boss if you know when you strike the enemy.

The best way to deal damage to this boss is to wait, and block his attacks until he gets ready for his heavy strike. In the process of his heavy strike, he is rendered defenseless for about 2-3 seconds. This gives you enough time to strike him twice. Repeating this process makes the whole fight easier, and the best way to defeat Gyoubu Masataka Oniwa.

Though the previous method is the safest, you can also try a different method by grappling on to him when a green circle shows up on the boss. This stuns him for 2 seconds allowing you to strike twice again.

Beating this boss is easy if you can wait to strike at the best moment, and that is when he is either stunned, or preparing for a heavy strike. Repeat until he is defeated and you will be rewarded with the Mechanical Barrel, which in turn unlocks the Prosthetic Tool Upgrades for you.

How to Upgrade

Now that you have the Prosthetic Tools Upgrade unlocked, you can pretty much upgrade your Prosthetic tool to make it more powerful. To do that, you need to return to the Sculptor at the Dilapidated Temple, where he will unlock the upgrades for you.

Unlocking an upgrade require three items. Money, Gunpowder and Scrap Metal. Once you have enough of these items, you can upgrade your Prosthetic Tool with the upgrade types that you want.
