How many left, Mim? Another great one, though I'm surprised you didn't mention the trick with the bonus, letting the bonus monsters kill everything that enters the keep for a good long while, makes the mission so much easier.
This is an awesome guide! wish ya had mad it when i did it. this would of saved a good bit of time. the only thing i would add would be probably the builds that your team used and attributes ect. other than that beautiful guid. and it so much better going with people
