Volcanic Behir - AI-generated fantasy Monster

Volcanic Behir

Behirs were created as weapons against dragons, and their hatred of dragons remains instinctive. This specimen has lived for decades in volcanic terrain, feeding on elemental energy until its natural lightning became threaded with magma heat. It recognizes dragon spoor immediately and may abandon a hunt to pursue a dragon intruder.

Spider Climb. The behir can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Ashen Stalker. The behir's movement through volcanic terrain does not create noise unless it chooses to. It has advantage on Dexterity (Stealth) checks made among basalt, ash, smoke, or volcanic rubble.
Dragon Hunter. The behir has advantage on saving throws against being Frightened by dragons or dragon-descended creatures.
Multiattack. The behir makes two attacks: one with its Bite and one with its Constrict.
Bite. Melee Weapon Attack: to hit, reach 10 ft., one target. Hit: 22 () piercing damage plus 11 () lightning damage.
Constrict. Melee Weapon Attack: to hit, reach 5 ft., one Large or smaller creature. Hit: 17 () bludgeoning damage, and the target is grappled (escape ). Until this grapple ends, the target is Restrained, and the behir can't use its Constrict attack on another target.
Volcanic Lightning Breath. The behir exhales superheated lightning in a 20-foot line that is 5 feet wide. Each creature in that area must make a Dexterity saving throw, taking 66 () lightning damage on a failed save, or half as much damage on a successful one.
Swallow. The behir makes one Bite attack against a Large or smaller creature it is grappling. If the attack hits, the target is also swallowed, and the grapple ends. The swallowed target is Blinded and Restrained, has Total Cover against attacks and other effects outside the behir, and takes 21 () acid damage at the start of each of the behir's turns. The behir can have only one creature swallowed at a time. If the behir takes 30 or more damage on a single turn from the swallowed creature, it must succeed on a 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.
