Special Abilities

Disease (Ex) Vicious filth fever: Bite–injury; save Fort DC 23; onset 1 day; frequency 1/12 hours; effect 1d3 Dex damage and 1d3 Con damage; cure 3 consecutive saves. The save is Constitution-based.

Painful Buzzing (Ex) Fluttering wings of giant dire filth flies produce painfully head-throbbing vibrations. When a giant dire filth fly moves by flying, all living creatures within 30 feet of their movement route suffer 4d6 points of nonlethal sonic damage. This damage counts as continuous damage for purpose of disrupting concentration.

Unbearable Stench (Ex) Giant dire filth flies stink with the odor of thousands of dead bodies and acres of dung. All living creature that starts their turn within 60 feet of a giant dire filth fly, become sickened for 1d4 rounds unless they make a successful Fortitude (DC 23) saving throw. Due to a very wide spectrum of the offending aroma, a successful saving throw doesn't provide temporary immunity, unlike the regular stench ability. This is a poison effect and its throw DC is Constitution-based.

Giant dire filth flies are enormous flies that are attracted to sufficiently large amounts of rotting flesh on massive battlefields, spoiled harvests, decay of whole cities, cadavers of great monsters, titans, and even dead gods—which might have been where they grew for the first time.
