BEHIR

A behir is a snake-like reptilian monster with a dozen taloned legs and a head like a crocodile's. Its banded scales range from ultramarine blue on its back to pale blue on its belly. It can move with considerable quickness and can climb well. It can also move like a snake by folding its legs close to its body and slithering along.

The behir attacks by biting and by constricting prey within its powerful coils. On the round after the victim is caught in the coils, the behir attacks with six of its taloned legs. 

Once per turn, the behir can discharge a 20-ft lightning bolt for 4d6 + 24 points of damage (save vs. Breath Weapon for half damage). Since the behir is immune to electricity, it can use its breath weapon on someone caught in its coils.

Behir are large enough to swallow man-sized prey whole. A score 4 above that needed to hit, or an unmodified 20, means that the behir has swallowed its prey. Swallowed victims will die in six rounds. After twelve turns, the victim will be totally digested and cannot be affected by raise dead spells. 

A swallowed victim can try to cut free, but weapon damage is reduced by 1, cumulatively, every round the victim is inside the behir. The behir has an internal armor class of 8.
