Heart Crystal Ore Mod - Add Healing Crystals to Minecraft World

This modification expands Minecraft's underground world with a new essence of health - heart crystal ore. The mining process is simple: healing energy fragments drop when mining porous peridot-rich stone with any quality stone pickaxe.

By combining these stones with other energy carriers, you can create a special healing device - regenerative polyandropspheres with instant effect. They restore health of two complete hearts to any existing game entity interacting with them. The relevant item transformation schematics are depicted in the accompanying illustrations.
