Bida
Level 8Attacks
Abilities
(1d6+6) bludgeoning damage, DC 26 fortitude save The monster deals the listed amount of damage to any number of creatures Grabbed or Restrained by it. Each of those creatures can attempt a basic Fortitude save with the listed DC.
A bida can Strike with its tail even while Grabbing creatures with it. The bida can have up to eight Medium or smaller creatures grabbed with its tail at a time; it can also grab Large creatures, but they count as four Medium creatures for this purpose.
By concentrating for 4 hours, the bida hides a small settlement. This is a 5th-rank Mirage spell, except the area is a 500-foot burst and creatures are invisible while inside structures in the area. The bida can conceal only one settlement at a time, and must concentrate on the effect for 10 minutes at the beginning of each day to maintain the illusion.
Trigger The monster's last action was a successful Strike that lists Improved Grab in its damage entry, or the monster has a creature Grabbed or Restrained Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with as a free action. This attempt neither applies nor counts toward the creature's multiple attack penalty. The monster can instead use Improved Grab as an action and choose one creature it's grabbing or restraining with an appendage that has Improved Grab to automatically extend that condition to the end of the monster's next turn.
Description
Bidas are black-scaled dragons with long, serpentine bodies and bat-like wings. Their legs and claws are smaller than those of most dragons, but their powerful undulating coils, like those of a boa constrictor, are potent weapons capable of squeezing the life from several unfortunate victims at a time.
A bida uses its impressive intellect and powerful magic to pose as a humanoid and infiltrate a settlement. Over the course of weeks or months, it establishes itself as a key member of the village, and only after it has become invaluable to the community does it reveal the terrible price of its assistance: regular offerings of flesh and gold. From this point on, the bida dwells almost exclusively within its smoggy lair, growing fat off the blood of its sacrificial offerings. To hide its presence from the outside world, a bida conceals its enslaved settlement in a large-scale illusion, leaving only a stand of jungle trees where once a thriving village may have been and ordering the townsfolk to destroy any roads in and out of town.
Bidas begrudgingly tolerate others of their kind, instead preferring the company of their small, tasty thralls. In rare cases, a pair of bidas may join forces to conquer a particularly large settlement, extracting that much more wealth from the populace as a result of their partnership.
