Sickening Cloud (Su): The fog that lingers around Tyrantfog zombies saps the endurance of creatures within it. A character who comes within 5 feet of a Tyrantfog zombie must make a Fortitude save (DC 13) or take 1 point of temporary Constitution damage. A single character only needs to make one saving throw per encounter with these creatures.

Infective Touch (Ex): The claws of a Tyrantfog zombie carry disease. A character wounded by a Tyrantfog zombie must make a Fortitude save (DC 13) at the end of the battle. Success indicates that the character fights off the infection. If the character fails the save, she sickens during the incubation period of 1d4 days, taking 1 point of temporary Strength damage at the end of that time. Each day thereafter, the character must make another Fortitude save (DC 13) or lose 1d2 points of Constitution and 1d4 points of Strength. The character must then make another saving throw to avoid the permanent drain of 1 point each of Strength and Constitution.

Tyrantfog zombies attack with their claws, spreading the foul disease that ended their mortal lives. They are smarter than normal zombies, and show cunning and at least a primitive sense of tactics in their attacks. Still, they fight relentlessly, with no motive of self-preservation.

These wretched undead are the remains of the priests and worshipers of evil deities who have been struck down by the raw power of another evil deity.

Tyrantfog zombies appear as rotting corpses surrounded by lingering wisps of dark fog. The fog fills their lungs and trickles from their noses and mouths. Their eyes and sharp fingernails, as well as any exposed bone, glow with a dim, emerald green light.
