Classic Leveling Guide - Nagafen's Lair (SolB)
Purple Area: This area has the animal mobs of SolB and is good for players 43 - 48. a noxious Spider, Death Beetle and a stone spider are some of the nameds. This area also leads to the Fire Giants and is marginally higher level than the kobolds at the start of the zone.
Red Area: This area has elementals and one of the most saught after camps in the zone, Efreeti Lord Djarn. Djarn drops Golden Efreeti Boots (GEBs) and Djarn's Amethyst Ring. These items will be some of the best twink items until PoP so this camp is always in very high demand. This part of the zone is good for players 48 - 50.
This is the area where the fire giants are in Nagafen's Lair. The fire giants are much more powerful than any of the other mobs in the zone - so powerful that they really aren't the best leveling location. By the time you can kill them you'll already be max level.
