The Purple Mist Mountains are a vast mountain range that undulates continuously for at least a thousand miles, and it is a zone populated by level 100 monsters. Only players above level 100 would form teams to come here to grind and level up.
The Purple Mist Mountains are enshrouded in a faint purple mist all year round. This mist contains no toxins, but it greatly restricts the players' visibility upon entering. Even perception is somewhat affected, making it very unfriendly for ranged profession players who fear close combat.
The monsters in the Purple Mist Mountains are a special type of demon creatures. From the Demon Hunting Dogs at the base of the mountains to the Doomsday Guardians at the peaks, nearly all kinds of demon creatures can be found within the range of the Purple Mist Mountains.
