Prosthetic Tools in Sekiro: Shadows Die Twice
- Grappling Hook, or more correctly a kunai with a rope attached, is an integral part of the Shinobi Prosthetic arm (and most likely the gameplay mechanics as well), allowing for vertical traversal of the landscape, and can probably not be unequipped.
- The Firecracker can be used to distract or stun enemies to allow the player to escape dire situations. Perhaps also to misdirect enemies?
- The Loaded Axe is a short axe that can overpower and break enemy shields.
Spear (?) One trailer appeared to show a prosthetic something like a spear, wherein the spearhead detached from the arm on a long pole, which could be used to pull out-of-range enemies closer.
- Conjecture: Some kind of fireball-cannon, it's assumed that this is also the item that can enhance the main katana with a fire buff. In the screenshots of the box-art we also see the protagonist with a second katana on his back, so dual wielding might also be a thing.
