The Rat Chain Puller has proven its worth at dozens of lesser tasks and has been entrusted with this sacred duty. At the first sign of trouble, the Puller will release a giant rat that is sure to terrorize adventurers.
The Puller is a weak specimen, and can be easily dispatched. Just don't miss. The Giant Rat is considerably more difficult to beat, with two health, an increased defense score, and a bonus of +2 on attack rolls.
