How to Acquire[]


  • Dad's Note cannot be rerolled or destroyed in most ways, such as with The D6 The D6, Void Void, or Abyss Abyss.
    • One of the three exceptions to this is TMTRAINER TMTRAINER, which causes Dad's Note to be replaced with a glitch item, softlocking the game.
    • Another exception is Spindown Dice Spindown Dice, which will reroll Dad's Note to Strawman Strawman, also softlocking the game.
    • There can also be a Dice Room 4 pips, which will reroll Dad's Note to a random item, also softlocking the game.
  • Dad's Note cannot be duplicated via Crooked Penny Crooked Penny, even if other items in the same room would be duplicated. Other duplication items such as Diplopia Diplopia work as normal.
  • Don't forget that the boss room of Mausoleum Mausoleum/Gehenna Gehenna II cannot be exited. Hence the only way to get out of there is by teleporting or picking up Dad's note.
  • The only item that can be taken in the boss room of this special version of Mausoleum Mausoleum/Gehenna Gehenna is Dad's Note. No other items will be spawned.
    • Treasure Room and Shop will still generate in this special floor as in usual floors, giving Isaac more options.
    • Despite this, Lemegeton Lemegeton pulls from the Boss Pool when used.
    • In Co-Op, extra boss items will still spawn for other players. These should be picked up quickly before the Ascent sequence begins.
  • It's recommended to skip the Treasure Room of this floor for now, since one of the items is hidden. During the Ascent, both items will be visible.
    • However, if Isaac has Dream Catcher Dream Catcher, he can predict the items inside. If one of them is worthy, Isaac can enter the treasure room and take it.
  • When obtaining outside the special Mausoleum Mausoleum/Gehenna Gehenna II boss room via cheats or by using Spindown Dice Spindown Dice on Sausage Sausage, it will just slowly fade the music out.


  • The boss room Dad's Note appears in is representative of the same one that would normally contain Mom if the player were to have chosen the alternative path stages. However, as Mom has been previously killed in Chapter 3, the boss room reflects that state as being completed with blood on the floor and no exit door as would normally be the scenario after defeating Mom.
  • Before update 4.0.2, Little Baggy Little Baggy caused the guaranteed Fool card in Depths Depths II to be replaced by a random pill. This is now a guaranteed Telepills.
  • Before update 4.0.2, Sack Head Sack Head had a chance to cause the guaranteed Fool card in Depths Depths II to be replaced by a sack.
