A serpentine monster with a dozen legs that can slither like a snake or move with considerable speed

The Behir is a serpentine monster that can slither like a snake or use its dozen legs to move with considerable speed. A behir is around 40 feet long and weighs about 4,000 pounds. The coloration of a behir ranges from ultramarine to deep blue with bands of gray-brown. A behir often knows the common language of the region.

This slithering, multi-legged blue reptile has a fearsome head crowned with two large, curling horns.

The serpentine behir crawls along floors and clambers up walls to reach its prey. Its lightning breath can incinerate most creatures, even as more powerful foes are constricted in its coils and eaten alive.

A behir's monstrous form resembles a combination of centipede and crocodile. Its scaled hide ranges from ultramarine to deep blue in color, fading to pale blue on its underside.

Cavern Predators

Behirs lair in places inaccessible to other creatures, favoring locations where would-be intruders must make a harrowing climb to reach them. Deep pits, high caves in cliff walls, and caverns reached only by narrow, twisting tunnels are prime sites for a behir ambush. A behir's dozen legs allow it to scramble through its lair site with ease. When not climbing, it moves even faster by folding its legs beside its body and slithering like a snake.

Behirs swallow their prey whole, after which they enter a period of dormancy while they digest. While dormant, a behir chooses a hiding place where intruders in its lair might overlook it.

Foes of the Dragons

In times long forgotten, giants and dragons engaged in seemingly endless war. Storm giants created the first behirs as weapons against the dragons, and behirs retain a natural hatred for dragonkind.

A behir never makes its lair in an area it knows to be inhabited by a dragon. If a dragon attempts to establish a lair within a few dozen miles of a behir's lair, the behir is compelled to kill the dragon or drive it off. Only if the dragon proves too powerful to fight does a behir back down, seeking out a new lair site a great distance away.

I've already eaten three giant bats, six troglodytes, and a mind flayer today, but that's okay. Plenty of room in my belly for you and your friends.

Behir

Lightning-Spewing Glutton

Twelve-legged, reptilian predators, behirs endlessly hunt for their next meal. Their short legs propel them quickly across floors and walls. Any prey that behirs can't chase down, they blast with breaths of powerful lightning.

Legends claim the first behirs were magically created by storm giants during an ancient, multiversal conflict between giants and dragons. The giants used their mastery of weather to alter the essence of blue dragons. The results were the first behirs, which served as hunters with a particular taste for dragon eggs.

Behirs live in sprawling cave systems and elaborate ruins where they can make the most of their exceptional mobility. They are mindful of areas where dragons dwell, as most dragons view behirs as dangerous abominations and attack them on sight. Nevertheless, behirs occasionally hunt for dragon lairs in the hope of finding and devouring unhatched dragon eggs.

You wouldn't believe all the great stuff I've swallowed! Now just climb on in here, and you can keep whatever you find.

A serpentine monster with a dozen legs that can slither like a snake or move with considerable speed

A behir is a particularly nasty subterranean beast with a crocodile's head on a 40-ft long snake-like body with twelve sets of legs. These creatures move very fast and can climb vertically at half their speed. Their main method of attacking is to bite and wrap their body around their prey and squeeze. On the second round they can still bite but the held victim is now subject to 6 claw attacks. Every 10 rounds a behir can also breathe a 20-ft lightning bolt that does 4d6+24 damage unless a save vs breath is made for half damage. Occasionally (on a 20) a behir will swallow its victim whole.
