players can increase their power by finding Blast Cores in the sandbox survival game. However, this coveted item comes with the risk of exploding one's character, since it only comes from one tricky explosive monster. Because of this, these drops are considered rare and are used pretty sparingly throughout the world, much like LEGO Fortnite's Sand Claws. It is a mid-to-late game item and as long as you learn how to stay alive, Blast Cores are worth finding.
