Lego Fortnite: Where To Get Marble
For your first couple hours in Lego Fortnite, you can pretty much get by with the stuff that's near where you originally spawned. But eventually, you'll need to upgrade to a better class of materials, and that classic granite isn't going to get the job done anymore. You'll need the next tier of building material: marble. Unlike the first tier of materials, this stuff isn't just lying around all over the place. You'll have to go looking for it.
Where to find marble in Lego Fortnite
Marble cannot be found anywhere on the surface--you'll need to venture into a cave to find it. You should stick with the temperate caves, for now, because the caves in the desert and snowy regions are probably more than you can handle right now if you're playing on normal survival rules.
Once you're in the cave, look for a white rock that's all over the walls in large patches. It's everywhere, and impossible to miss. But if you've arrived in this cave with a common (white) pickaxe, you'll find it's too tough to mine.
How to mine marble in Lego Fortnite
Even though Marble is relatively easy to find, since it's a tier 2 material you won't be able to mine it with your standard basic common-rarity pickaxe. You need an uncommon (green) pickaxe instead, and to make one of those you'll need skeleton bones and knotroot rods, which are made from knotroot. You'll find knotroot all over caves as well, but you'll need an uncommon (green) forest axe to harvest it. Fortunately, we've got a whole separate guide on knotroot that you can consult for everything you need to know about it, including how to get an uncommon forest axe.
Once you've got your knotroot rods and skeleton bones, you can craft an uncommon pickaxe and mine the marble. Fun fact: you can also mine marble with dynamite, but that's a little bit advanced for this point. Dynamite is frequently more efficient than your pickaxe, though, since marble tends to spawn in big groups.
