I have gotten all the timed achievements except this one. I'd appreciate any advice I can get. I did view a video, but since it dealt with version 1.3, this info is no longer valid. I have reached a point where I got a number of minions into deal with Lucius, but many just wander around, without attacking him, and it takes forever to knock him out. I have managed it, while working under the speed run attempt, but never get him out before the clock runs out.
