Corlagon's was probably the trickiest place so far. Sometimes I had to back up a Beacon or two to get out of a tight spot. Worked it out though and didn't have any other problems. Silver Helm in Myst was also kind of tight in places. Found out that that secret door with the switch by the Master Monk will close if you Lloyd's Beacon in there, so had to maneuver the mobs so I could run from the switch to the door.

Icewind Keep was easier than I expected. Set a beacon at each door switch but really just kept moving forward one beacon at a time till I go into the treasure room. Set a beacon there and then beaconed back out and sealed the secret door again.

Gharik's Forge up next. That should be pretty easy - I've done that by mostly running through in the past. Varn looms in the future as the big challenge.
