They are a dangerous hybrid of rat and poisonous scorpion that has bred in the Shepherd's Hollow area. They have very low morale, but attack in thick swarms that are 5' across. Their body chemistry makes them very vulnerable to acid attacks, and will make a morale check as soon as they smell an acid attack in use.
