Wererats, derogatively called "ratmen", were shapeshifters Cursed with Lycanthropy, able to transform into a bipedal Dire Rat form. Like many other lycanthropes, they were vulnerable to magic and silver, but could otherwise regenerate most wounds. They were cannibals, eating uninfected humans and subsisting on what they could scavenge or steal, and often lead packs of non-magical Rats. They often carried disease, as they were found in environments such as sewer systems, swamps, and other areas of refuse.
While not as strong as other lycanthropes, possessing strength roughly equivalent to average Humans in their hybrid Beast form, Wererats were nimble, intelligent, cunning, and adept at surprise attacks. they shared the animal instinctiveness of all Lycanthropes and were markedly more dexterous than humans as well as a little more hardy.
A wererat never lived alone if they could help it, though they did not tend to form strong interpersonal relationships beyond a pack mentality; love and marriage were almost alien concepts to them. They delighted in pitting their superior cunning against surface-dwellers, seeing the cities that tended to be above their lairs as hunting grounds where they could steal food and wealth by killing its inhabitants in an almost parasitical manner.
