The rat king boss fight is a chaotic swarm of dozens of rats fused into a single, writhing mass. You have to focus fire on the central, larger rat that seems to coordinate the others. It will command waves of smaller rats to attack, and you'll need area-of-effects to clear them fast. It's a gross but satisfying fight.
