The andrenjinyi can breathe air and water. \n'b'  Innate Spellcasting . The andrenjinyi\xe2\x80\x99s spellcasting ability is  Charisma  (spell save DC 19, +11 to hit with spell attacks). It can innately cast the following spells, requiring only verbal components: \n'b'   At will :  create water ,  speak with animals ,  stoneshape  \n'b'  3/day each :  control weather ,  dispel magic ,  reincarnate  \n'b'  1/day each :  blight ,  commune with nature ,  contagion ,  flesh to stone ,  plant growth  \n'b'   Magic Resistance . The andrenjinyi has advantage on saving throws against spells and other magical effects. \n'b'  Magic Weapons . The andrenjinyi\xe2\x80\x99s weapon attacks are magical. \n'b'  Actions \n'b'   Multiattack . The andrenjinyi makes two attacks, one with its bite and one with its constriction. If both attacks hit the same target, then the target is Swallowed Whole. \n'b'  Bite .  Melee Weapon Attack : +15 to hit, reach 20 ft., one target.  Hit : 36 (4d12 + 10) piercing damage. \n'b'  Constrict .  Melee Weapon Attack : +15 to hit, reach 5 ft., one target.  Hit : 36 (4d12 + 10) bludgeoning damage, and the target is  grappled  (escape DC 20). Until this grapple ends the target is  restrained , and the andrenjinyi can\xe2\x80\x99t constrict another target. \n'b'  Rainbow Arch . The andrenjinyi can instantaneously  teleport  between sources of fresh water within 1 mile as an action. It can\xe2\x80\x99t move normally or take any other action on the turn when it uses this power. When this power is activated, a rainbow manifests between the origin and destination, lasting for 1 minute. \n'b'  Swallow Whole . If the bite and constrict attacks hit the same target in one turn, the creature is swallowed whole. The target is  blinded  and  restrained , and has total  cover  against attacks and other effects outside the andrenjinyi. The target takes no damage inside the andrenjinyi. The andrenjinyi can have three Medium-sized creatures or four Small-sized creatures swallowed at a time. If the andrenjinyi takes 20 damage or more in a single turn from a swallowed creature, the andrenjinyi must succeed on a DC 18  Constitution  saving throw at the end of that turn or regurgitate all swallowed creatures, which fall  prone  in a space within 5 feet of the andrenjinyi. If the andrenjinyi is slain, a swallowed creature is no longer  restrained  by it and can escape from the andrenjinyi by using 15 feet of movement, exiting  prone . The andrenjinyi can regurgitate swallowed creatures as a free action. \n'b'  Transmuting Gullet . When a creature is swallowed by an andrenjinyi, it must make a successful DC 19  Wisdom  saving throw each round at the end of its turn or be affected by  true polymorph  into a new form chosen by the andrenjinyi. The effect is permanent until dispelled or ended with a  wish  or comparable magic. \n'b'  About \n'b' A gigantic, black-headed snake is over 60 feet long and sheathed in brilliant scales, each andrenjinyi is splashed with vibrant patterns of every imaginable color. The air around these serpents is heavy, redolent of the quenched red desert after a torrential thunderstorm. \n'b' Andrenjinyi are the descendants of the Rainbow Serpent, the first and greatest spirit of the world\xe2\x80\x99s beginning. The Rainbow Serpent\xe2\x80\x99s children are dichotomous nature spirits of land and sky, sun and rain, male and female, and birth and destruction. \n'b'  Last of their Kind . The Rainbow Serpent shed andrenjinyi like cast-off scales during her primordial wanderings, but she has created no more since she ascended to the stars. While andrenjinyi are ageless fertility spirits, they cannot themselves reproduce; each one is an irreplaceable link to primeval creation. \n'b'  Hunt and Transform . Andrenjinyi are naturally aquatic, preferring to live in deep, fresh, life-giving rivers and lakes. The serpents usually  attack  intruders unless they approach with the correct rites or offerings, which require a successful DC 20  Intelligence  ( Religion ) check. Andrenjinyi hunt as other animals do, but they transform devoured prey into unique species with their Transmuting Gullet ability, creating mixed gender pairs. An andrenjinyi\xe2\x80\x99s sacred pool and surroundings often shelters a menagerie of strange and beautiful animals. \n'b'  Demand Obedience and Ritual . When offered rituals and obedience, andrenjinyi sometimes protect nearby communities with drought-breaking rains, cures for afflictions, or the destruction of rivals. Revered andrenjinyi take offense when their petitioners break fertility and familial edicts, such as prohibitions on incest, rape, and matricide, but also obscure obligations including soothing crying infants and the ritual sacrifice of menstrual blood. Punishments are malevolently disproportionate, often inflicted on the whole community and including baking drought, flooding rains, petrification, pestilence, and animalistic violence. Thus, tying a community\xe2\x80\x99s well-being to an andrenjinyi is a double-edged sword.'
