The astral devourer\xe2\x80\x99s individual serpents are connected via a hive mind. It can telepathically communicate with any of its individual serpents within 1 mile of it, and it can\xe2\x80\x99t be surprised. \n'b'  Magic Resistance . The astral devourer has advantage on saving throws against spells and other magical effects. \n'b'  Swarm . The astral devourer can occupy another creature\xe2\x80\x99s space and vice versa, and the devourer can move through any opening large enough for a Tiny serpent.

The astral devourer flings biting astral serpents outward. Each creature within 20 feet of the astral devourer must make a DC 16  Dexterity  saving throw, taking 14 (4d6) piercing damage and 14 (4d6) poison damage on a failed save, or half as much damage on a successful one. The astral devourer regains  hp  equal to the single highest amount of piercing damage dealt by this spray. \n'b'\n'b' REACTIONS \n'b'\n'b'  Divide . When an astral devourer that is Small or larger takes bludgeoning, piercing, or slashing damage, it can split into two new astral devourers if it has at least 10  hp . Each new devourer has  hp  equal to half the original creature, rounded down. New astral devourers are one size smaller than the original. While within 1 mile of each other, the new astral devourers share one collective mind. \n'b'  Recombine . When one or more astral devourers that are Small or smaller and share a collective mind are within 5 feet of each other, they can combine into a new astral devourer. The new astral devourer is one size larger than the largest original creature, and it has hp equal to the combined total of the original creatures. The new astral devourer\xe2\x80\x99s hp can\xe2\x80\x99t exceed the normal hp maximum of a Medium astral devourer. \n'b'\n'b' ABOUT \n'b' A swarm of strange, faceless gray snakes flies through the air-wingless, as if through water.\xc2\xa0Their mouths are rasping irises of gnashing fangs, and the sides of each snake are lined with milky,\xc2\xa0 unblinking eyes.\xc2\xa0When enough serpents on the Astral Plane gather, they form a collective creature called an astral devourer.\xc2\xa0The astral devourer has a hive mind made up of all the minds of its component creatures and possesses a great cunning that makes it more adept at hunting. \n'b'  All for the Whole . The individual astral serpents that make up the astral devourer have no thoughts or wills of their own, and the collective freely uses the individuals as weapons. The astral devourer often flings serpents at hard-to-reach prey to consume it.\xc2\xa0The flung serpents return to the astral devourer, bringing the consumed life force back to the collective. When food is particularly scarce or the devourer is in danger, it can split into subgroups of the main collective, feeding the individuals while keeping the whole safely dispersed. \n'b'  Planar Hunters . Hunger constantly drives astral devourers.\xc2\xa0They love the taste of sentient planar travelers, and they roam the multiverse, favoring desolate landscapes. Reports indicate they\xe2\x80\x99re adept at finding portals between worlds and relentlessly hunt prey through these portals.'
