Where to Find Blast Cores

Blast Cores can be found primarily in Desert biomes, specifically caves with visible smoke puffs arising from the ground. Inside these caves can be found Lava Crabs which explode upon contact, making these sites home for these explosive creatures.

Here are the specific locations where you can find Blast Cores:

  • Desert Cave: Situated near the center of the desert, this large cave houses numerous Lava Crabs and Blast Cores.
  • Smaller Desert Caves: Found across the desert floor, these caves often house one or two Lava Crabs and a Blast Core.

Tools Needed to Get Blast Core in LEGO Fortnite

To create Blast Cores, the following tools will be required.

  • Rare Pickaxe: At minimum, this pickaxe must be equipped to mine Blast Cores effectively and quickly. Upgrade it further for quicker mining operations.
  • Weapons: Lava Crabs can be aggressive creatures that will attack you at sight. Be prepared with weapons like Assault Rifles or Shotguns to effectively repel them.

Tips for Defeating Lava Crabs

Lava Crabs can be fast and explosive enemies, making them deadly threats. Here are some strategies for defeating them:

  • Avoid Close Combat: Maintain distance from Lava Crabs and use ranged weapons as attacks against them.
  • Avoid Attacks: Lava Crabs will attempt to rush at you; use your jump and sprint abilities to dodge their attacks and avoid becoming victims of their aggression.
  • Attack them quickly: Lava Crabs have an impressively large health bar; focus your fire and strike before they can explode!
  • Explosives can cause great damage to Lava Crabs and even kill them instantly, with Grenades and Rocket Launchers often being successful at doing this.

Once you defeat a Lava Crab they’ll drop a Blast Core that can be mined using your Rare Pickaxe & collected.

Additional Tips

  • Blast Cores can also be found as rewards for completing quests and challenges.
  • Keep an eye out for chests and containers, as these could contain Blast Cores.
  • If you are having difficulty in sourcing Blast Cores, seek help from other players or trade with them for them.
