Graves or Mounds are naturally-appearing objects in the world that can be found individually in Forests or in a large group in Graveyards (which are characterized by large shrouds of fog). They may be found with or without a nearby Headstone, though graves without headstones can only be found in graveyards. Graves can only be dug up once, and each world has a limited number of them.
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 50% chance of finding a random Trinket (4.17% chance for each individual Trinket), 15.35% chance each of a Blue or Red Gem and 3.07% chance each of Gears, a Life Giving Amulet, or Nightmare Fuel. Each grave dug costs the player 10 .
Headstones are objects that usually spawn next to a Grave. They currently have no use (other than marking nearby Graves on the map) and cannot be destroyed.
List of possible epitaphs:
- "Here lies some guy. Blah blah blah."
- "This headstone is blank"
- "It says: 'Milk. Eggs. Bacon.'"
- "Hey that's my name!"
- Developer names (Set Piece)
- "Not sick, just coffin."
- It says "Catch you later."
In the Reign of Giants DLC, if a player has already dug up a Grave, they can bury an item called Webber's Skull inside the grave. Once this is done, light will shine on the mound, Webber will appear and jump into the grave, closing it, and finally a large group of Spiders will appear. Additionally, Webber will be unlocked as a playable character if he has not been already. Doing this will also reset the grave, and it can be then dug up again for the normal loot.
