If your group is having difficulty clearing the mobs in the room with Warlord Kilrok Caroeth, use a Insta-Fizz Fuzzlecutter (found randomly throughout the buildings of Chardok; Looks like a glowing wine glass) to spike the drinking keg outside the barracks. This will put all the mobs in the lower room of barracks to sleep and make the barracks servant stationary at the bottom of the stairs instead of roaming back and forth.
