Primal Knife
The Primal Knife is an unlockable knife whose exclusive upgrade makes it indestructible, addressing the game’s knife durability system.
How it works
The weapons reference says the Primal Knife is unlocked by destroying all Clockwork Castellans and describes it as having infinite durability. The upgrade guide also lists destroying all Clockwork Castellans as its condition and says its exclusive upgrade makes it indestructible. Knives have limited durability and can break after repeated use; the Merchant can repair them. The exclusive upgrade follows full standard-stat upgrades under the general system description.
