Hook

The Hook is a crafting material used solely to craft the Grappling Hook. It has a chance to drop from Skeletons, Undead Miners, Hoplites and Undead Vikings in the Marble Caves, Ice biome and Cavern layer. It also has a chance to drop from Piranhas in the Jungle, Underground Jungle, Cavern and Underground layer.

Tips

 * The Grappling Hook can be obtained very early into the game by going to the Jungle, where Piranhas spawn above ground.
 * It is much more profitable to craft Grappling Hooks with spare Hooks rather than sell them as a raw material.
