Ratting
Ratting is a status effect that is inflicted by a rat king's special attack for 20 turns if the character is in a 9-square radius from it. Every 20 points of duration decrease intellect by 1. Every 50 points decrease strength by 1. And every 25 points decrease perception by 1. Also there are increasing chances to vomit, increment the counter of the rat mutations category, and mutate.
The death of the rat king removes this effect.
