Undead Turkey
Magically created undead turkeys are created by evil magic wielders, or spontaniously in magically warped areas. These creatures hate all living beings, even their creators. Undead turkeys are fast and dangerous. They travel in flocks up to 20. Undead turkeys cannot fly.
Undead turkeys have excellent eyesight and reduce, by 5%, a character's chance of hiding in shadows and are only surprised on a roll of 1 or 2.

Combat
Undead turkeys hate all living creatures and attack them on sight. The undead turkey uses their vicious serrated beak that inflicts 1d8 points of damage. In addition, the undead turkey carries a disease. Those who are struck with the undead turkey's beak attack must save vs poison, or suffer the effects of turkey fever.
Turkey fever causes sweating and uncontrolled gobbling. Every 24 hours that an individual is infected, they lose 1 point of intelligence and 1 point of wisdom. If either intelligence, or wisdom are reduced to 1, the victim believes themselves to be a turkey.
Turkey fever may be treated with magic, or with the herbalism non-weapon proficiency. Every successful use of the herbalism non-weapon proficiency allows the victim to roll another saving throw vs poison to throw off the disease. Intelligence and winsdom return at a rate of 1 point each per day.
Undead turkeys are immune to sleep, charm, hold, death magic, poisons, and cold-based spells. A holy element inflicts 2-8 points of damage to an undead turkey.

Habitat/Society
Undead turkeys have no set habitat, they roam all over Athas seeking to kill the living.

Ecology
Undead tukeys are unnatural creatures and have no role in the ecology of Athas.
