**_Multiattack_**. The behir makes two attacks: one with its bite and one to constrict.
**_Bite_**. Melee Weapon Attack: +10 to hit, reach 10 ft., one target.
_Hit_: 22 (3d10 + 6) piercing damage.
**_Constrict_**. Melee Weapon Attack: +10 to hit, reach 5 ft., one Large or smaller creature.
_Hit_: 17 (2d10 + 6) bludgeoning damage plus 17 (2d10 + 6) slashing damage. The target is grappled (escape DC 16) if the behir isn't already constricting a creature, and the target is restrained until this grapple ends.
**_Lightning Breath (Recharge 5-6)_**. The behir exhales a line of lightning that is 20 feet long and 5 feet wide. Each creature in that line must make a DC 16 Dexterity saving throw, taking 66 (12d10) lightning damage on a failed save, or half as much damage on a successful one.
**_Swallow_**. The behir makes one bite attack against a Medium or smaller target it is grappling. If the attack hits, the target is also swallowed, and the grapple ends. While swallowed, the target is [blinded](srd_conditions_blinded.md) and restrained, it has total cover against attacks and other effects outside the behir, and it takes 21 (6d6) acid damage at the start of each of the behir's turns. A behir can have only one creature swallowed at a time. If the behir takes 30 damage or more on a single turn from the swallowed creature, the behir must succeed on a DC 14 Constitution saving throw at the end of that turn or regurgitate the creature, which falls prone in a space within 10 feet of the behir. If the behir dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 15 feet of movement, exiting prone.
