Poison (Ex): Bite, Fortitude save (DC 22), initial damage 1d6 temporary Dexterity, secondary damage 2d6 temporary dexterity. The jawg's poisonous bite is particularly effective against dragons and their kin. The DC for Dragons and creatures with the Reptilian subtype is 30.

Pounce (Ex): If a jawg leaps upon a foe during the first round of combat, it can make a full attack even if it has already taken a move action.

Spells: All Jawg cast spells as 12th-level sorcerers (save DC = 13 + the spell's level.)

Skills: The jawg's two heads give it +2 racial bonus to Listen, Spot, and Search checks.

Jawgs despise all dragons and live to hunt and kill their hated foe. Most camp secretly near a dragon lair, gathering information on the dragon's routine, intelligence, age, and so on, before making a surprise assault. They often hire dozen of scouts and spies to gather information for them and will sometimes hire parties of adventurers to delve into a dragon's lair to test its defenses.
