Idol

This Idol of the god Kozah is found deep within the excavation of an ancient temple in the Archaeological Site area south of Lighthouse. It can only be accessed if you agree to provide security for Charleston Nib, who leads the excavation. The idol has two uses in the game:
 * 1) Removing the idol from the temple summons its guardian, Doomsayer, who is worth 4000 xp if you can defeat him.
 * 2) The idol, along with the Ancient Armor from the Firewine Ruins, can be traded to the Ghost of Ulcaster for the sword The Vampire's Revenge, although why you would want to trade two useless items for an almost equally useless cursed sword is not known.

In-Game Description
"This idol depicts Kozah the Stormstar, a long-extinct god who was venerated and feared among the less-powerful strata of ancient Netherese society. Worship of this god of storms, earthquakes, strife, and rebellion was outlawed by many of the civilization's powerful archwizards. Many Kozahyn shrines and temples were therefore built in secretive, underground locations where the devout were better able to escape detection."
