This event item is the first event item in Sinnoh unavailable through normal means and must be obtained from cheating.
At the apex of Mt. Coronet, the player must stand upon the tile which resembles the Azure Flute. When the Flute is played, a staircase appears at the base of the tile, allowing the player to climb up and challenge Arceus.
- If Arceus is defeated during any moment of the Azure Flute event, the player may come back to Spear Pillar to rechallenge it using the same method. If the player successfully captures Arceus, then the flute will no longer become playable, giving the message "The Azure Flute echoed hollowly".
- The Azure Flute's design somewhat resembles an Ocarina, a musical instrument.
- It also somewhat resembles a human heart that has been colored purple.
