UEE HEE HEE, THE KEY, THE KEY. A MARVELLOUS FUN IS ABOUT TO BREAK FREE. WON'T YOU LET YOURSELVES OUTSIDE?
The Door Key is a Key item that can open the door in the ?????? floor in Card Castle, leading to Jevil's prison. The Door Key can be created by asking Malius to fix the three Broken Keys. However, Malius notes that the key holds a "terrible energy" and advises the party to never use it.
- When used, the Door Key creates a small door which admits the party to Jevil's cell.
- The Door Key is mistakenly called the Prison Key when it is fixed by Malius.
