Leather is a Common material used in a variety of crafting and upgrade recipes. While it is one of the more basic resources in the game, it remains useful throughout progression because many weapons, items, and upgrades require it in large quantities.

Obtainment:

Leather is primarily obtained as a drop from various humanoid enemies across multiple stages of progression. Because it can be collected from both early and mid game NPCs, players can farm it naturally while leveling, completing quests, or gathering other resources.

Common enemies that can drop Leather include Pirates, Brutes, Gladiators, Mercenaries, Marine Captains, Lab Subordinates, Pirate Millionaires, Pistol Billionaires, Jungle Pirates, and Forest Pirates. Since these NPCs are spread across different areas, Leather remains one of the more accessible crafting materials to farm when needed.
