~DIO's Diary


DIO's Diary (DEO's Diary in-game) is a brown journal with a gold outlining on the cover. It spawns around the map and has the same spawn rate as the Steel Ball or the Stone Mask. It can also be won from the Arcade, but it is rather rare. The Diary is a requirement for The Heaven's Plan in order to obtain The World Over Heaven or to talk to Pucci to evolve Whitesnake to C-Moon. This is not required to evolve C-Moon into Made In Heaven.


  • This item was part of the Heaven update on December 3rd, 2020, which added DIO's Diary, C-Moon, Green Baby, and Enrico Pucci to the game.
  • Before the Heaven update, DIO's Diary was only used for obtaining C-Moon. With the Heaven update arrival, it is now also used for The World Over Heaven.
  • This item is droppable, being one of the two Stand evolving items that can be dropped (the other being the Left Arm Of The Saint's Corpse).
  • You can have up to 10 DIO's Diaries in your inventory at a time.
  • Before, you used to be able to complete the 25 Wins in the 1v1 Gamemode by getting 50 kills instead, the 50 1v1 kills alternative was removed due to "Kill Traders", people who would cheat the system by abusing a bug which including hitting your opponent then having them reset. This can still be done for the 50 Steel Ball Run kills, but it is riskier because the other person may not reset if they are trolls or want to win SBR.
  • This item is named "DEO's Diary" in-game in order to avoid copyright issues.
  • DIO's Diary is from Part 6 of JoJo's Bizarre Adventure: Stone Ocean.
  • DIO's Diary is in fact, a book that contains the ways to obtain "Heaven".
  • After gaining the stand The World Over Heaven, the diary will disappear.
