Ambush drakes generally stalk their prey as a coordinated pack. They start by using their breath weapons and focus attacks on affected creatures, ignoring quicker fleeing prey.

Breath Weapon (Su): 30-foot cone, once every 1d4 rounds, slow (duration 7 rounds), Will DC 17 negates. Ambush drakes are immune to the breath weapons of other ambush drakes. The save DC is Constitution-based.

Poison (Ex): Injury, Fortitude DC 17, initial and secondary damage 1d6 Dex. The save DC is Constitution-based.

Telepathic Link (Ex): Ambush drakes share a communal consciousness, enabling them to communicate telepathically with other ambush drakes. A group of ambush drakes within 30 feet of each other are in constant contact. If one is aware of a particular danger, they all are. If one in the group is not flat-footed, none of them are. No ambush drake in the group is considered flanked unless all are.

Skills: Ambush drakes have a +4 racial bonus on Hide checks.
