The Cleric is a free-willed priest, tending the needs of the local people with his particular talents. On Athas, clerics draw their magical energy directly from one of the four elemental planes: earth, air, fire, or water; not from any manner of deity. A cleric may be either a freeman or a slave.
Unlike the clerics of most other worlds, who serve deities, the Clerics of Athas instead must serve the elemental/paramental powers. Commonly refered to as Elemental Priests.
Clerics are average fighters, but can wear armor and bear weapons, unlike wizards.
The spells a clerics throw are often destruction and healing. Also because of their class traits, clerics can turn undead monsters.
