Ruby 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 ruby and what you’ll use it for.

How to get ruby in Lego Fortnite

Ruby is only found in “dry valley” caves — so first, you’ll need to find a desert biome, 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).

Inside the cave, look for shiny red deposits — those are your ruby. 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 brightcores.

What you’ll use ruby for in Lego Fortnite

Ruby is an important and valuable resource for the midgame. You’ll need a gem cutter (20 marble slab, 5 rough amber, 5 sand claws from desert wolves, and 3 sand shells from desert rollers) to turn the rough ruby you collect into cut ruby.

The most useful thing you can craft with cut ruby is the inner fire charm (3 wool thread, 5 cut ruby, 8 brightcore, and 3 blast cores from rollers in desert caves) that will keep you warm when you venture into the Frostlands.
