- This article is about the crafting material. For the class of grappling tools, see Hooks.
The Hook is a crafting material used solely to craft the Grappling Hook. It has a 4% (1/25) chance to drop from Skeletons, Undead Miners, Hoplites and Undead Vikings in the Marble Caves, Underground Snow and Cavern layer. Also it has a 3.3% (1/30) chance to drop from Piranhas in the Jungle, Underground Jungle, Cavern and Underground layer.
- Hooks, and by extension the Grappling Hook, can be obtained very early into the game by going to the Jungle, where Piranhas spawn aboveground.
