  • Obsidian can be found in the lava caves that you'll encounter in the Dry Valley biomes, as an ore on the walls you'll need to mine
  • It can be used to create powerful tools, like the Epic Pickaxe that will help you gather even more rare resources

Obsidian is an extremely valuable material in LEGO Fortnite, so you may be wondering where you can find it and get your hands on it so you can put it to the best use - so I've broken down the best way for you to do just that.

Where to find Obsidian in LEGO Fortnite

In LEGO Fortnite, Obsidian can be found in lava caves in the more arid Dry Valley biomes of the map. While they can be hard to find, entering them will transport you inside an exceptionally hot space, so be sure to have plenty of items, food and materials that can cool you down.

Additionally, as the name suggests, you’ll have to navigate pools of lava once you’re inside, so be sure to mind your step. Unless you're in Creative Mode that is. In which case, feel free to float toward it.

Once in there, the Obsidian will be hanging in deposits on the walks and need to be hit with a pickaxe several times to break it off. Make sure you’re either taking a few pickaxes with you or one with high durability so they won’t break so easily.
