Graveyard

The graveyard is a new mini-biome added in the 1.4.0.1 update, created whenever there is a high enough amount of Tombstones in one area. They are marked by background effects including heavy fog, dulled colors, and even lightening when enough graves accumulate. Graveyards allow nighttime enemies (such as Zombies and Demon Eyes) to spawn during daytime, and also spawn Ghosts.

Tips

 * It is advisable to avoid letting graves accumulate around one's base during the early game (especially in Expert and Master mode), as the Ghosts spawned have relatively high health and damage output compared to starting character.
