The behir can take the Dash or Disengage action on its turn as a bonus action.
The behir exhales a line of lightning that is 15 ft. long and 5 ft. wide. Each creature in that line must make a DC 14 Dexterity saving throw, taking 44 (8d10) lightning damage on a failed save, or half as much damage on a successful one.
The behir makes two attacks: one with its bite and one to constrict.
Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 13 (2d8+4) piercing damage.
Melee Weapon Attack: +7 to hit, reach 5 ft., one Medium or smaller creature. Hit: 10 (1d12+4) bludgeoning damage plus 10 (1d12+4) slashing damage. The target is grappled (escape DC 14) if the behir isn't already constricting a creature, and the target is restrained until this grapple ends. Grappled: • A grappled creature's speed becomes 0, and it can't benefit from any bonus to its speed. • The condition ends if the grappler is incapacitated. • The condition also ends if an effect removes the grappled creature from the reach of the grappler or grappling effect, such as when a creature is hurled away by the thunderwave spell. Restrained: • A restrained creature's speed becomes 0, and it can't benefit from any bonus to its speed. • Attack rolls against the creature have advantage, and the creature's attack rolls have disadvantage. • The creature has disadvantage on Dexterity saving throws.
