Enter a misty graveyard filled with the surly dead.
Place five or six Tombstones close together and the area becomes a Graveyard biome - mist rolls in, the music changes, pop. Tombstones drop where players die, or craft/buy them; you'll want a graveyard anyway for its unique crafting recipes and the ecto mist vendors' extras, so build one at base and keep it.
