Requires Minecraft Forge. The Plague Gem Mod adds two new ores to Minecraft- Plague Ore and Dark Ore. Plague Ore can be mined with an Iron Pick or higher. Dark Ore can be mined with a Stone Pick or higher. Both ores are extremely rare. If you mine Plague Ore, you get a Plague Gem. If you mine Dark Ore, you get Dark Matter! If you combine both in a special way, you get Fused Plague. (see picture) If you fill an entire crafting table with Fused Plague, you get a Plague Source block! This block acts as a craftable Zombie Spawner! You can use the Plague Gems to craft the Epic Plague Sword which does enough damage to 1-hit K.O. any boss. You can use a Plague Pickaxe to mine any ore and Obsidian!
