All-Around Vision
This monster can see in all directions simultaneously and therefore can't be flanked.
Swarm MindThis monster doesn't have a single mind (typically because it's a swarm of smaller creatures), and is immune to mental effects that target only a specific number of creatures. It is still subject to mental effects that affect all creatures in an area.
Extraneous Flesh
Frequency three times per day
Trigger A Strike scores a critical hit on the bhanyada swarm
Effect A critical hit might simply sever a component chunk that the bhanyada can lose without much harm. The bhanyada swarm attempts a DC 11 flat. On a success, it doesn't take any extra damage from the critical hit (although it takes other effects normally, such as critical specialization effects).
Odor of Rot (aura, olfactory)10 feet. Creatures other than aberrations that enter or start their turn in the bhanyada's aura must succeed at a DC 27 fortitude save or become Sickened 1 (Sickened 2 on a critical failure). A creature that succeeds at its save is temporarily immune for 1 minute.
Swarming Bites
Each enemy in the bhanyada swarm's space takes 2d6 bludgeoning damage (DC 30 reflex). On a failed save, a creature is also Slowed 1 for 1 round.
Bhanyadas without much cohesion between their fleshy components roil around one another in a ghastly swarm of malodorous gobs of flesh.
Gobbets of flesh left behind from an untidy meal or a surgical procedure typically rot away if left where they lie, but when steeped in areas of powerful lingering magic or eldritch radiation, these bits of loose tissue might achieve some measure of animation, perhaps sprouting thick limbs to move about or tiny, multifaceted eyes to see. Near the magic-suffused Ghantibhu Pits in the caverns located beneath southern Vudra, where ripples of magic are powerful enough to rend the air and transform stone, these tiny, rotting castoffs form into even larger amalgamations called bhanyadas.
Tied to Open Bridge
Bhanyadas are almost never encountered outside the Open Bridge region in southern Vudra, as the magic of the Ghantibhu Pits beneath that region create them. Bhanyadas taken away from Open Bridge quickly decay into a repulsive slurry, although though it isn't clear whether their demise is due to being too far from the magical energies that animated them or too far from the masses of other bhanyadas that give them cunning and vigor.
Bhanyada Familiars
A component of a bhanyada swarm makes a useful, if gruesome, familiar. A character who can take a familiar and who has encountered a bhanyada can choose a bhanyada familiar, which must have the burrower and darkvision abilities. The owner would be wise to anoint the familiar with perfumes or find other solutions to mask the unpleasant smell.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
AberrationAberrations are creatures from beyond the planes or corruptions of the natural order.
SwarmA swarm is a mass or cloud of creatures that functions as one monster. Its size entry gives the size of the entire mass, though for most swarms the individual creatures that make up that mass are Tiny. A swarm can occupy the same space as other creatures and must do so in order to use its damaging action. A swarm typically has weakness to effects that deal damage over an area (like area spells and splash weapons). Swarms are immune to the grabbed, prone, and restrained conditions.
