Its in-game description reads "Cute sword with a Halloween pumpkin design." Like the Antique Sword, it has the slow 5-hit combo, and its stats are quite balanced : it only has 3 stats at 0. You can only find this sword in dungons' chests, it cannot be invented or bought in any way. It's a medium-tier weapon (Tier 6) : it'll gain 4 Synthesis Points (SP) per level-up.
