Ghost

Ghosts are a hostile Mob found in the Dwarven Mines. They only spawn in a special area called The Mist. They have 2 million health (may be incorrect). Their appearance is that of an invisible charged creeper, similar to those spawned by the Wither Cloak Sword ability.

They may drop a Volta, which is a drill fuel, Sorrows which is used to make Sorrow Armor, Ghostly boots which seem to be a cosmetic armor only (may be incorrect), Bag of Cash (Sold to shops for 1,000,000 Coins), and Plasma which usage is Unknown.

Tips: Ghosts can be killed from a range using a Phantom Rod
