Kunark Leveling Guide - City of Mist
Blue Circles = the lowest level places to camp in the zone with the easiest monsters. Although you still need to be careful what you're pulling.
Purple Area = slightly higher level than the blue circles and slightly more rewarding.
Red Area = This is the hardest area in the ground floor of City of Mist. This area also leads to the upper levels which contains most of the hardest monsters to kill in the zone.
