General Mayhem
From Drunkapedia
Unscheduled, Unruly - Death all over. General mayhem spreads across the land when the world needs some action.
Many smaller mobs will also be near these event hot-spots and are usually in the form of an animated drink. Yes, like a whiskey or a wine hopping around and shooting at you.
Mayhem Event mobs can usually be found near most towns.
