2016 Halloween Chest 12


An exclusive 2017 Halloween Rune will be available during the event. In this event Rune you will be able to get one of the exclusive Halloween 2017 weapons, or a rune from the previous year to maybe earn an older exclusive item!

When you transmute a 2017 Halloween Rune, you have a small chance to receive the rare bonus item from this year: the Shield of the Skeleton King!



The Legendary Hats system has been modified :

Starting from update 0.28.0, every time a Rune is opened your chance to get a Legendary increases slightly.

Once a legendary hat has been transmuted, its obtention rate goes back to its initial value.

That new system is retroactive! It means that the more Runes you opened without getting legendaries, the more chances you have to get one during your next transmutation.


From servers list, you can now click on "Create a server" in order to choose your maps, your modes and your server capacity.

Your server will be automatically hosted in the nearest area in order to optimize the latency.

The same player won’t be able to open many servers simultaneously, you will have to wait for your server to be empty and to shut down before you open a new one.
