Where can you find Saltpeter in New World? In New World, Saltpeter is used to craft gunpowder, which in turn is a key component in crafting musket cartridges. Depending on your chosen character build and the weapons you favour, this could be an absolutely essential resource for you. But exploring Aeternum in search of a specific resource can be an intimidating prospect due to the sheer size of the island, so we've put together this guide to help you find the best Saltpeter spawn locations.
Fortunately, it's easy to predict where Saltpeter is going to spawn in New World. Unlike some other resources, Saltpeter isn't native to any particular region of the map. Instead, Saltpeter Ore nodes spawn in caves across Aeternum. Caves in New World tend to cluster around the coast, as you might expect, but you can find them inland as well, particularly at higher elevations.
The only real drawback to finding Saltpeter once you're inside the caves is that it looks quite a bit like any other rock. Saltpeter Ore is often slightly darker in color than its surroundings, and protrudes from the floor a bit more, but it's not hugely obvious. However, the good news is that within the confines of a cave, you should see the interaction text identifying Saltpeter appear on-screen if there's any nearby.
