Hello, player! Welcome to Blood and Deepslate, a mod for those seeking more challenge and a more gradual progression in Minecraft!

Most of Minecraft won't change, however the main challenge lays 64 blocks below the surface. Want to learn more about this challenge and know about how to oversome it? Make sure to check out this list of this bone-grinding mod's features:

Important Changes

  • Mining coal creates a cloud of coal dust (just like irl :D) with a 50% chance.They explode violently if there's a fiery block nearby. Dissapears on it's own very slowly.
  • Going lower than y = 4 in the overworld gives mining fatigue and slowness if no gas mask is equipped.
  • Going lower than y = -28 in the overworld results in mining fatigue II, slowness II and nausea as well as damage from suffocation. Can although be avoided using a gas mask.


  • Molybdenum Ore/Deepslate Molybdenum Ore: A new ore that you can find between y = -63 and y= -12. Drops raw molybdenum which is further useful for gas masks and hardhats.


  • Raw Molybdenum: Drop from the molybdenum ore. Can be smelted into a molybdenum ingot.
  • Molybdenum Ingot: Can be used to make a hardhat or smelted further into molybdenum oxide.
  • Molybdenum Oxide: A mandatory ingredient for the filter for the gas mask.
  • Filter: A crafting ingredient for the gas mask.


  • Gas Mask: Negates the debuffs given to the player for entering the deepslate layer.
  • Hardhat: Destroys the blocks that fall on the player's head when equipped (pointed dripstone and anvils inclusive).

Other Changes

  • New structure: the mineshaft elevator. Looks like an opening on the surface that leads to a cross of 2 short mineshaft corridors with some ores and a chest of goodies (or a trap).

Come try this little expansion to the vanilla gameplay yourself. Hope you enjoy! :D
