World Zero’s limited-time Halloween event is now live, offering exclusive seasonal rewards. To claim these special items, participants must complete two major challenges: obtaining an essential Rune and Key through specific in-game actions. Here’s a breakdown of the requirements for each objective.
Acquiring the Halloween Key
Securing the Key requires defeating the Fallen King in a challenging raid. After obtaining the Rune (detailed below), head to the dungeon located to the right of the Coin Shop. The battle scales to your level, making it accessible regardless of progression. Strategic tips include:
- Prioritize collecting power-ups that restore Health and Energy during combat
- Watch for glowing indicators marking the Fallen King’s attack zones
- Eliminate Ghoul Skeletons first during clock rituals when the boss becomes invulnerable
- Dispatch smaller enemies quickly to avoid sustained damage
- Equip stat-boosting companions before engaging
Successfully completing this raid rewards players with the Key item.
Securing the Mystical Rune

To earn the Rune, journey to the Spooky Courtyard via the pumpkin coin teleporter in the main lobby. Search for three glowing gourds in randomized locations, which commonly appear in these areas:
- Adjacent to the World Portal
- Near the Bank entrance or its connecting stairway
- Within maze corridors or central intersections
- By the Fallen King’s gate
- Close to the Coin Shop
Collecting all three gourds grants the Rune plus 250 seasonal tokens for additional rewards.
