Looted from Loot-Filled Pumpkin in The Headless Horseman (Hallow’s End Instance).
Only available during Hallow's End

Notes:

Introduced in 2025, this demonic steed can only be obtained during Hallow’s End. This festival occurs during later October each year, but the precise dates change annually so check your in-game calendar. During the event period you can use the Dungeon Finder to access a special festival boss version of the Headless Horseman. The mount has a chance of dropping from the Loot-Filled Pumpkin you receive after defeating him, but only on your first attempt per account per day, and on a character of sufficient level to receive the epic version of the Pumpkin. Your chance of receiving the mount reportedly increases with each daily attempt.
