Hallow’s End is a spooky celebration of the Forsaken breaking away from the Scourge. This holiday is celebrated all across Azeroth with trick-or-treating, apple bobbing, and more! This holiday is an in-game version of Halloween, though it is not a one-day-only event.

Tricky treats are obtained through dailies and the pumpkins spread throughout inns on the map. You will get two treats for every inn you visit, as a one-time-only reward, along with a potential for a mask, wand, or other fun holiday items. You then spend the tricky treats at vendors outside of your capital cities.
