Ancient Jack O Lantern

The Ancient Jack O Lantern is an Event Weather NPC added during the Halloween Event. Unlike passive atmospheric effects, this is a spawning vendor-style encounter: it appears for 10 minutes every 2 hours, giving you a tight, predictable window to interact with it before it vanishes again.

That fixed 2-hour cadence is the whole game here. With each appearance lasting only 10 minutes, you can set a timer and plan your sessions around it, logging in shortly before the spawn so you are ready the moment the Ancient Jack O Lantern shows up. Halloween NPCs like this typically gate access to limited candy currency, themed seeds, or seasonal rewards, so missing a cycle means waiting two more hours for the next chance.

To capitalize, treat the 10-minute window as a hard deadline and finish any trades, claims, or interactions immediately rather than browsing. Stockpile whatever event currency it grants while the Halloween Event is live, since the NPC and its limited offerings disappear entirely once the season ends. Consistent, on-schedule visits across a day add up to far more seasonal loot than sporadic check-ins.
