Fear Mongerer

The Fear Mongerer is a Shop NPC located in the Village, next to the Bank. He spawns at the location of the Event Stand, replacing it with a giant pumpkin, and only appears around the time of the Spooky Festival. During the hour-long event, you can collect candies to trade with the Fear Mongerer for various items, such as upgraded enchanted books and accessories. He appears for 1 hour before the event starts, stays through the event, and despawns one hour after the event ends.

Trivia

 * There was a glitch, when someone was standing on the spot where the Fear Mongerer spawns (not during the spooky event), you were able to access the shop. This was supposedly patched but has been accessed during times other than during the spooky event. This glitch works with an armour stand taken in the Fear Mongerer's place.
