Elite Giant Rats are actually a crossbreed between a Giant Rat and a Brown Bear. These creatures are specifically bred by Greasel Greedigutt in order to have a guard which has an ability to fight like a bear and also have the love for the sewers that is characteristic of a rat.
Elite Giant Rats look just like rats except they are six feet long. They are able to swim like rats and fight on their hind legs (if trained) as do bears. The bite of an Elite Giant Rat has a 10% chance per wound inflicted of contracting a serious disease. Unlike Giant Rats, Elite Giant Rats have absolutely no fear of normal fire, and if they are in the presence of Giant Rats, there is a 70% chance that the Giant Rat will show no fear of fire.
Elite Giant Rats are collectors of many items, but they are selective. They seem to have some knowledge of what trinkets they find are worth keeping.
