Where to find obsidian in LEGO Fortnite?

You can only find obsidian in one place in LEGO Fortnite—the Dry Valley biome. This area is easy to spot because it has darker sand than other areas, big cliffs, and lots of cacti. It's different from the lighter sandy areas found elsewhere in the game.

Finding the Dry Valley biome takes time and effort. You need to explore a lot. Once you get there, you have to find a cave, which is not easy because these caves are hidden and often surrounded by lava. To help find these caves, players can use their map to mark cave entrances.

How to get obsidian in LEGO Fortnite

Getting obsidian in LEGO Fortnite takes a few careful steps. Here's a straightforward guide to help you gather this valuable resource:

  • Prepare for the Heat: Before heading out, make sure you have the right gear to handle the heat in the Dry Valley caves:
    • Cool-Headed Charm: This is made from three silk threads, three sand shells, and one marble. It helps you stay cool in the hot caves.
    • Snowberry Shakes: Mix two snowberries with one milk to make this shake. It gives you longer protection against the heat, which is important for exploring hot areas.
  • Find the Dry Valley Biome: This biome has darker sand, tall cliffs, and many cacti. It's not near the starting areas, so you need to explore a bit to find it.
  • Look for a Cave: In the Dry Valley, find a cave. These caves often have lava and can be tricky to spot. Use your map to mark where the caves might be to help you search.
  • Search for Obsidian: Inside the cave, look for shiny black rocks on the walls or ceiling. These are obsidian. Keep an eye out for other useful materials too.
  • Mine the Obsidian:
    • Use a rare pickaxe, which you can make from three flexwood rods and three sand claws. You get flexwood from cacti in the biome.
    • Hit the obsidian until it breaks and collect it.

After you collect obsidian for the first time, you'll learn how to make obsidian slabs. These are important for more advanced crafting in the game.
