Effects[edit | edit source]

  • The Cracked Key is a single-use 15►Red Key Red Key.

Notes[edit | edit source]

  • The Cracked Key's main purpose is to allow unlocking Tainted characters in Home Home without having to rely on finding the Red Key.
    • To create a Cracked Key (once unlocked), drop any trinket in a Boss Room or a Treasure Room on any floor before acquiring 15►Dad's Note Dad's Note, including the room you get Dad's Note in.
      • While trinkets are fairly common, there is always a chance one doesn't appear naturally. This chance can be avoided by clearing three boss rooms without taking damage, which is guaranteed to cause Perfection Perfection to spawn.
    • After starting the Ascent by collecting Dad's Note, the trinket left behind will have become a Cracked Key in the corresponding room.
  • The Cracked Key can also spawn in the same condition as any Card.
  • 15►Little Baggy Little Baggy will turn all Cracked Keys into pills instead, rendering them unavailable, even during the Ascent.
