Where to find blast cores in Lego Fortnite Odyssey
To get blast cores, you’ll need to take out these crab-like volcano creatures called blasters in the dry valley biome. There are lots of them in dry valley caves as well. These enemies will chase you down and blow up after they see you, so you’ll need to be very careful. We recommend used ranged weapons and kiting them to take them out.
You can find a ton of these in the dry valley biome itself, especially during the day. At night, most of the spawns will get taken up by wolves and skeletons, so day time is your best bet.
What uses blast cores in Lego Fortnite Odyssey
You need blast cores for a few utility items, like the gem cutter and the metal smelter.
