PFS StandardJiidon

Legends among jiidons explain that many ages ago, when magic was wilder and of less distinct order, a magic-touched rat consumed the discarded fingernails of a human, and the gods granted that rat the ability to shapeshift into a copy of that human. True or not, jiidons are seemingly normal rats who share the blessing from this story. It's unclear where the first jiidon was born because their descendants live among rat and humanoid populations around the world. In their original forms, jiidons are extremely difficult to distinguish from an ordinary rat and often even finds a home leading its non-sapient kin.

After eating the discarded fingernails of a humanoid, however, a jiidon can assume the shape of the clippings' owner, resembling the subject in all of the obvious and superficial ways, with several subtle differences. Their ears are a little larger and sometimes come to a small point. Their teeth continue to grow for their entire lifetimes, so they must regularly chew on stones, bark, and other hard materials to file their teeth down and conceal their true nature. The whiskers that grow from the sides of their faces also require daily trimming. Jiidons are mostly harmless, but their powers provoke alarm among those who know of them. Mothers scold their children not to clip their nails after nightfall, lest a lurking jiidon seize a sliver that got lost in the dark. Though as cautious as any rat, most jiidons want nothing more than to transform and take a place in humanoid society. In order to reduce suspicion, they've been known to target those who are unpopular among their neighbors. The gratitude they feel when they do replace a humanoid can sometimes be seen in their actions, revealing the fact that the target has been replaced or endearing jiidons to those who didn't appreciate the original's attitude.

Jiidons from large families will often seek a role that grants them access to nail trimmings, such as a cleaner or doctor, and pass the gift of humanoid form through the family.

Melee [one-action] jaws +11 [+6/+1] (finesse), Damage 2d6+4 piercing plus sneak attackConsumed Fragments [one-action] (concentrate, polymorph, primal) The jiidon takes on the form of any Medium or Small humanoid creature whose fingernails or similar fragments they've consumed within the last week, gaining the effects of a 3rd-rank illusory disguise spell to impersonate the creature for 8 hours; this is a polymorph effect rather than an illusion effect. Once a jiidon has transformed into a creature in this way, they must eat that creature's fingernails again to transform into it again. If a jiidon consumes the nails of a specific humanoid three nights in a row, they can take the form of that humanoid at will but can't use this ability to imitate any other humanoid thereafter.Sneak Attack The jiidon deals an additional 1d6 precision damage to off-guard creatures.Tactical Gnaw [two-actions] The jiidon uses their nearly indestructible teeth to chew through even the toughest armor, leaving an opponent vulnerable. The jiidon makes a jaws Strike. On a successful attack, if the target is wearing armor with Hardness 10 or lower, the armor becomes broken. This Strike doesn't further damage armor that's already broken.

Sidebar - Advice and Rules Playing a Jiidon

While jiidons don't have ancestral rules in this book, a player interested in creating a jiidon character can use the beastkin versatile heritage to emulate a jiidon who has obtained a permanent humanoid form. The player should work with the GM to determine who the jiidon is imitating and what complications this might have.
