Breath Weapon (Su): 20-foot line, once every 10 rounds, damage 7d6 electricity, Reflex DC 17 half. The save DC is Constitution-based.

Constrict (Ex): A Halruaan behir deals 2d6+6 points of damage plus 1d4 points of electricity damage on a successful grapple check. It can make six rake attacks against a grappled foe.

Rake (Ex): Six claws, attack bonus +9 melee, damage 1d2+2 plus 1d4 electricity.

Static Discharge (Ex): When angry or agitated, a Halruaan behir generates electricity with its body. This discharge deals 1d4 points of electricity damage to any creature hit by the behir, touches it, or makes a successful melee attack against it with a natural or metal weapon.

Skills: Halruaan behirs have a +8 racial bonus on Climb checks. A Halruaan behir can always choose to take 10 on climb checks, even if rushed or threatened.

A Halruaan behir is likely to rely on its breath weapon when threatened, because hatchlings are often trained not to bite, maul, or crush. Some Halruaan behirs are trained to constrict prey - or intruders - to the point of unconsciousness. Since they emit discharges of electricity when agitated, any form of combat with a Halruaan behir can be dangerous.
