Venture into the fiery depths of LEGO Fortnite Odyssey’s Dry Valley biome, where the elusive Obsidian awaits in lava-filled caves. Armed with a rare pickaxe and heat-resistant gear like Snowberry juice or the Cool-headed charm, players must brave scorching temperatures and treacherous terrain to mine this vital resource. Mastering the hunt for Obsidian is key to crafting powerful tools and upgrading your village, making this quest a thrilling challenge across mobile, Nintendo, PlayStation, and Xbox platforms.
How to get obsidian in Lego Fortnite Odyssey
To get obsidian in LEGO Fortnite Odyssey, you need to head to the Dry Valley biome, which is characterized by darker sand, tall cliffs, and cacti. Once there, find a cave within this desert area, often filled with lava. Inside the cave, look for shiny black obsidian rocks on the walls or ceiling. To mine obsidian, you must use at least a Rare-level pickaxe, crafted from materials like flexwood rods and sand claws found in the biome. It’s advisable to prepare for the heat by using items such as the Cool-Headed Charm or drinking Snowberry Shakes to gain heat resistance. After mining, you can convert obsidian into obsidian slabs at the Stone Breaker for advanced crafting and upgrades.
Obsidian is only found in “dry valley” caves – so you’ll need to find a desert biome first, and then you’ll need to find a cave. You’ll know you’re in the right place when you start getting hot and seeing cactuses (cacti?) everywhere. (Those are good for gathering flexwood.)
Once you’re there, you’ll just have to wander until you find a cave. However, caves in the desert biome are extremely hot, so you’ll have to prepare in order to survive:
- Make a cool-headed charm (3 silk thread, 3 sand shells, 1 marble) at an upgraded crafting bench
- Make some Snowberry Shakes (2 snowberries, 1 milk) – remember that cows drop milk when you pet them – at a juicer (8 planks, 8 marble slabs from a stone breaker, and 5 knotroot rods).

Inside the cave, look for shiny black deposits – those are your obsidian. You’ll need a rare pickaxe (3 flexwood rods and 3 sand claws) or better to mine them.
These caves are the same places you’ll find copper, rubies, and brightcores.

Are lava caves in the Dry Valley biome the only secret spots for Obsidian
