Multitudinous, disease-ridden rodents that will eat anything. Avoid contact with humans, but may attack if defending their nest or if summoned and commanded by magic (e.g. see Wererat, p39).


  • Disease: Bite has a 1-in-20 chance of infecting the target (save versus poison). The disease has a 1-in-4 chance of being deadly (die in 1d6 days). Otherwise, the victim is sick and bedridden for one month.
  • Afraid of fire: Will flee fire, unless forced to fight by summoner.
  • Attacking in water: May attack without penalty; excellent swimmers.
