Boss Rat King

Rat King is a boss monster found in the WOW Industries building.


One Rat King will always be found in the last room of the WOW Industries sewage system during The Poisoned Water, and must be defeated in order to proceed with the mission.

A stronger version of the Rat King always spawns on Floor 93 of the Deepest Ruin.

Behavior Edit

  • Melee, quick strike with the scepter
  • Melee, the sequence of a propeller stroke then a slow but powerful stroke of scepter
  • Halfway, belly shot
  • Ranged, throws his propeller around him like a boomerang
