Brightcore is a resource you’ll have to find in Lego Fortnite if you want to level up your village or make better weapons and tools. Finding it is going to take a bit of prep work, though, as it is only found in one biome.

Our Lego Fortnite guide will explain how to get brightcore and what you’ll use it for.


How to get brightcore in Lego Fortnite

Brightcore 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) — cows drop milk when you pet them — at a juicer (8 planks, 8 marble slabs from a stone breaker, and 5 knotroot rods).

We’ve only seen brightcore near lava, so if your desert cave doesn’t have lava inside, you may have to look for another one.

In the cave and near the lava, look for bulbous red-orange deposits — those are your brightcore. 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 obsidian, copper, and rubies.


What you’ll use brightcore for in Lego Fortnite

Brightcore is an important resource for the midgame. You’ll need brightcore to build the metal smelter to process copper and it’ll finally let you crafet some lighting fixtures for your village.
