–Wilson, after digging a grave
Graves or Mounds are naturally-appearing objects in the world that can be found singularly in forests or in a large group in a graveyard (which is characterized by a large shroud of fog). They may be found with or without a nearby Headstone, though graves without headstones can only be found in actual graveyards.
DebugSpawn code: "mound" .. however, it only spawns the grave, as it does not show the headstone.
Each grave dug with a Shovel has a 10% chance to spawn a Ghost, which will be aggressive towards the player. Otherwise, the player has a 10% chance to get an Amulet, Gravedigger Item, Blue Gem, Red Gem, Gears, or Nightmare Fuel. Once dug, the grave will not respawn. Each world has a limited number of them.
Digging a grave takes 4% of the Shovel's durability and 1% of a Regal Shovel's. Each grave dug also causes the player to lose 10 points of Sanity.
