An overgrown, ancient Iksar city (Old Sebilis) deep in Kunark's jungle — an endgame group dungeon whose crypts and chambers are guarded by Froglok Kunzar armies. It offers some of the best non-raid gear in the game; groups camp the Crypt and King room for loot.
Extreme difficulty — high enemy density and roaming frogloks make trains and adds lethal; deep spots (Crypt, King room, Trakanon's cavern) require a full, well-geared group.
A complete group with an Enchanter is effectively mandatory for crowd control; focus-farm the Crypt and King room for the best loot.
