Came across one on Voss this morning. I'm guessing he's a boss. He even has minions.
Drumond Champion 45 X: 1834 Y: 25
Yeah, I've been getting alot of messages from people claiming to have found a world boss lately.
There is basically one thing that makes it a world boss.
When you mouse over an enemy and it has their class in the bottom right
eg Champion, Elite, Strong
It will say 'Heroic World Boss'
