Giant rats, also known as dire rats, were a species of large rodent.
Giant rats worked exceptionally well in groups, taking advantage of their numbers to attack more efficiently. They attacked a target by biting them with its sharp incisors. Giant rats avoided attacking stronger creatures, especially those wielding fire, unless driven by extreme hunger or compelled to do so by a wererat or vampire. Giant rats were excellent swimmers, as such they were just as dangerous in the water as they were on land.
Giant rats were common found in subterranean areas such as crypts, dungeons and sewers. They were also found in great numbers within graveyards, where they dug a network of tunnel to gain access to the corpses found within.
