As of 7/14/2016, a New mode has been added to PvP on Riltak Island: JUGGERNAUT MODE.
You'll be interested, because in Juggernaut Mode, a player becomes the "Juggernaut". When this happens, said player will have an onyx crystal floating above their head and for 5 minutes they will get:
- A major Health boost
- Infinite Ammo on all Weapons/Staff
- +100% Damage
- +100% XP
If the players kill the juggernaut within the time limit, everyone who helped out will get a lot of Money and XP, AND there's a 1/5000 chance a player will be awarded with Onyx. Then a new player will get the chance to become the juggernaut.
"But Beta how do I become juggernaut?!"
The only way to become a Juggernaut is to find a small Onyx crystal that randomly spawns around the Snowy areas on Riltak Island.
And finally, here is a picture of a player being Juggernaut. (Again, you'll notice by seeing the Onyx Crystal above their head.)
