The latest update: Trick or Treat (17 Oct 2026)
The 17 October patch is the Halloween event. The Wiki describes it as similar to the 2025 Trick or Treat event, with a new layer: costume collecting.
- Trick or treating returns. Visit the houses around the map, light the candles to activate a house, then take a trick or a treat.
- Costumes matter. Collect hat, torso, pants and shoes pieces. With four pieces you have a better chance of candy instead of a trick; matching pieces pay more.
- Costume sources: costume boxes, chests, and random drops from wolves, cultists and other enemies.
- Costume closet: build one at the crafting table for 3 wood.
- Outfits: dinosaur, pirate, astronaut, werewolf, lobster and mummy.
- New Halloween lobby with Happy's shop, plus candy-purchased furniture (spooky crock pot, coffin chair, pile of skulls, spooky braziers, standing coffins, shrapnel grenade and more).
The event is seasonal. The costumes and the candy shop rotate out when the Halloween window closes; the underlying Trick or Treat mechanic has returned in previous years.

What changed for players (the short version)
- Classes are always available now. The 19 September rework removed the rotating stock; you can buy any class at any time, with a few daily discounts.
- Three new classes entered the pool on 5 September: Escape Artist (10), Elemental (400) and Woodsman (600).
- Daily quests were added on 5 September and are now one of the best repeatable Diamond sources.
- Halloween is live from 17 October: costumes are the new progression layer, and candy is the event currency.
- The Deer is Hurt event is over. The injured-Deer storyline ended in December 2025; the Deer is healed and hostile again.
