Bone Collector

Bone Collector is part of the Halloween Event 2025. Players speak to the Death Collector (who can be found south of home, outside of the Gamble Zone) to receive a timed assignment to gather named bones from specified bosses found across the world. Bones only drop while the task is active, are untradeable, and are used solely to complete the event. Completing the assignment awards a Death's Trick or Treat Box with a chance at tradeable cosmetics (Evil Pumpkin Helmets and the Sanguis pet). There is a 1‑in‑50 chance the box explodes with spooky effects, instantly killing the player and giving no reward.

How it works

• Talk to the Death Collector to start a special timed task.
• Your task is to collect bones from specified bosses around the world.
• You have 60 minutes to obtain all required bones.
• If you fail to collect them in time, the Grim Reaper spawns and instantly kills you (task fails).
• Bones only drop while you are on the task (no stockpiling).
• Bones are untradeable and can only be used to complete the Bone Collector event.
