Breath Weapon (Su) 20-foot line, once every 10 rounds, damage 7d6 electricity, Reflex DC 19 half. The save DC is Constitution-based.

Constrict (Ex) A behir deals 2d8+8 points of damage with a successful grapple check. It can make six rake attacks against a grappled foe as well.

Improved Grab (Ex) To use this ability, a behir must hit a creature of any size with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity.

If it wins the grapple check, it it establishes a hold and can attempt to constrict the opponent or swallow the opponent in the following round.

Rake (Ex) Six claws, attack bonus +15 melee, damage 1d4+4.

Swallow Whole (Ex) A behir can try to swallow a grabbed Medium or smaller opponent by making a successful grapple check.

A behir that swallows an opponent can use its Cleave feat to bite and grab another opponent.

A swallowed creature takes 2d8+8 points of bludgeoning damage and 8 points of acid damage per round from the behir's gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the gizzard (AC 15). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.

A behir's gizzard can hold 2 Medium, 8 Small, 32 Tiny, or 128 Diminutive or smaller opponents.
