You have three slots for Prosthetic Tools at one time. You can use the ones that suit your playstyle. To use Prosthetic Tools, you need Spirit Emblems that can be acquired by defeating enemies. In addition to this, you can also increase the number of Spirit Emblems you can carry using a skill.

How to Upgrade Prosthetic Tools

The Prosthetic Tools are already very helpful but the tools can be upgraded for a wide area use and more effect.

For upgrading the Prosthetic Tools, you first have to obtain the Mechanical Barrel item. The item will be dropped after you defeat your first main boss.

The boss is fairly difficult to defeat, hence, before defeating him you should be practiced enough to handle him.

The boss is one of the tougher enemies for whom you need the upgrades in Prosthetic Tools and as you will not have them yet, you have to be skilled in using the items that you already possess like your Katana or the Grappling Hook.

The Grapple Hook can be used to drag your enemy towards you and before he recovers, you can land him your attacks by using your katana.

Deflect him and try to work on increasing his Posture Meter then you can finish him off with the Deathblow.

After you acquire the Mechanical Barrel item, go to the Dilapidated Temple and interact with the Sculptor. You will require the in-game currency and the items that you will be asked for.

Fulfill the conditions and you will successfully unlock the upgrades for the Prosthetic Tools.
