The Haunted Pumpkin is the Halloween event pet, with a playful two-sided ability.

Haunted Pumpkin Event Halloween
Trick or Treat: Treat: heals you when your HP falls below 45%. Trick: curses the monster you fight, so it deals less damage and takes more.

How to get it
During Halloween, complete The Pumpkin Keeper's Curse in Haunted Aeven. The reward is a Haunted Pumpkin of Event rarity, once per character. Outside Halloween the quest cannot be started, but Haunted Pumpkins can still change owners in a trade.
