Dead Core is an object unobtainable by players through normal means. This item's information is present in the game files, but not intended by developers to be in players' possession.
Dead Core Blocks are blocks that are found in the core of moon. It's incredibly dense and will take a while to mine, which upon doing so drops nothing. This block cannot be obtained by any means, including through admin, as it exists only as a material in the game files, not possessing a material item like many other materials do. Its primary purpose seems to be to prevent the player from digging so far down that they die at the bottom of the world.
- Dead Core Block's materialID is 666, which is ironic as it is at the bottom/"nether" side of moons.
- The exact health that Dead Core Blocks have is 2048 health, a fully upgraded matter manipulator will take approximately 2 minutes, 50 seconds to mine (however, any drill better than a Copper Drill could destroy it much faster). This same amount of health is also possessed by Brains found in The Ruin.
- The image files to support Dead Core Blocks being painted are present in the code, which means it would theoretically be possible to paint them.
