If a metal  rat swarm  is destroyed, it will disintegrate into a pile of worthless metallic dross but will also leave behind d6+4 tiny but perfect gemstones that served its constituent creatures as eyes and which are worth 100 gp each. \n'b'  Keen Smell . A metal rat Swarm has advantage on  Wisdom  ( Perception ) checks that rely on smell. \n'b'  Wounding Bites . A metal rat Swarm\xe2\x80\x99s members have long, strong, razor-sharp fangs that can cut deeply and shear through veins, tendons, and bone and cause terrible wounds that require greater than usual effort to treat. Anyone who suffers damage from a metal  rat swarm \xe2\x80\x99s bites must make a DC 15  Constitution  saving throw and, failing it, will take 1d6 points of necrotic damage at the start of each of its turns until the wound is staunched. This can be accomplished with any sort of magical  healing  that restores at least 4  hit points  to the wounded creature or a successful DC 20  Wisdom  ( Medicine ) check. \n'b'\n'b' ABOUT \n'b' Jinshu Shu are  elemental  creatures that look like rats made of various sorts of precious metal, silver (40%) and gold (30%) being the most common, but copper (20%) and platinum (10%) also being possible (swarms of Metal Rats might consist entirely or one sort of such creature or be a mix of two or more kinds of them, as the storyteller desires). Little beasts of this sort are created on the  Elemental  Plane of Earth through a convergence of metallurgic, metaphysical, and  elemental  fire and air energies and are the  size  of normal rats but much heavier, typically weighing between seven and 10 pounds. They have spiky metallic hairs and eyes that look like gemstones, typically sapphires for silver rats, rubies for gold ones, emeralds for copper ones, and diamonds for platinum ones. \n'b' Even though they are elementals, Metal Rats still eat and sleep like their non- elemental  cousins. They are omnivorous and can subsist on a wide variety of foods \xe2\x80\x94 their favorite things being rotting organic material, lilac shrubs, and wood of all sorts \xe2\x80\x94 and will single-mindedly devour such things when they are available unless dissuaded in some way. \n'b' Metal Rats are very adaptable and might be found almost anywhere on the Prime Material Plane, although given the choice they are most likely to inhabit places where they can find their favorite foods, to include gardens, jungles, and graveyards. They might be active at any time of day or night but are especially likely to be found foraging and engaging in other activities in the hours right after dark when the Evening Star can be seen or before dawn when the Morning Star is present. \n'b' Metal Rats are not easily spooked and will generally respond favorably to creatures \xe2\x80\x94 especially Humans, demihumans, humanoids, and even monkeys and apes \xe2\x80\x94 that are friendly or kind to them in some way (e.g., feeding them, especially delicious things like sandalwood chips). \n'b'  Revered Rodents . Metal Rats are often kept as pets, animal companions, familiars, or guards by Earth-dwelling beings like Dao; Dragons, which often view them as living treasures; and people that include alchemists, jewelers, metalworkers, and necromancers. They also sometimes dwell in the temples of various deities, especially those associated with the element of Earth, treasure, craftsmen, and death, where they typically serve as companion animals or guardians. In cultures that observe the Lunar New Year and adhere to the Asian Zodiac, spellcasters often summon Metal Rats to take part in annual celebrations (e.g., with Conjure Lesser Elementals, which will summon one such creature, or conjure lesser  elemental , which will summon a swarm of them). They are then displayed, doted on, marched in parades, fed treats, and otherwise honored for the duration of their stays \xe2\x80\x94 and, in some traditions, sacrificed at their conclusion so that their valuable remains might be added to the temple treasuries. They might also be summoned in tactical situations for purposes of things like quickly destroying wooden structures. \n'b'  Good Poop . One of the things that makes Metal Rats so valued is that their scat is pure metal commensurate with the sort associated with the animal (i.e., copper, silver, gold, or platinum), and every day one will produce 2d4 pellets, each equal in weight to a normal coin. A swarm of Metal Rats will produce 6d6+4 pellets of precious metal a day and it is at the storyteller\xe2\x80\x99s discretion whether these are all one sort of metal or a mix of two, three, or four types. \n'b'  Destructive Devourers . Metal Rats  attack  inanimate wooden objects with advantage and swarms of them are therefore able to quickly destroy things like barrels, chests, doors, catapults, and the like. At the storyteller\xe2\x80\x99s option, up to once per round a creature in a space occupied by a metal  rat swarm  must make a DC 13  Dexterity  saving throw or have destroyed one non-magical wooden item it possesses (e.g., a quarterstaff, a wooden shield, the haft of a spear). \n'b'  Equine Antipathy . Metal Rats hate horses, to include creatures of similar appearance and those that are partially equine in form (e.g., donkeys, Centaurs). In combat they will tear into such creatures recklessly, whether individually or in swarms, gaining advantage on their  melee attack  rolls and +2 on their  damage rolls , but attacks made against them when they are doing so are also at advantage.'
