Behirs speak Common.

Combat

A behir usually bites and grabs its prey first, then either swallows or constricts the opponent. If beset by a large number of foes, it uses its breath weapon.

Breath Weapon (Su): Line of lightning 5 feet wide, 5 feet high, and 20 feet long, once a minute; damage 7d6, Reflex half DC 19.

Improved Grab (Ex): To use this ability, the behir must hit with its bite attack. If it gets a hold, it can attempt to swallow or constrict the opponent.

Swallow Whole (Ex): A behir can try to swallow a grabbed Medium-size 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. The swallowed creature takes 2d8+8 points of crushing damage and 8 points of acid damage per round from the behir's gizzard. A swallowed creature can also cut its way out by using claws or a Small or Tiny slashing weapon to deal 25 points of damage to the gizzard (AC 20). Once the creature exits, muscular action closes the hole; another swallowed opponent must again cut its own way out. The behir's gizzard can hold two Medium-size, four Small, eight Tiny, sixteen Diminutive, or thirty-two Fine or smaller opponents.

Constrict (Ex): A behir deals 2d8+8 damage with a successful grapple check against Gargantuan or smaller creatures. It can use its claws against the grappled foe as well.
