When starting a new level dig a huge circle and let you imps fortify before doing anything else.This way you can build up your dungeon without being invaded by pestering little heroes..

Train, train and train again...

Always take prisoners, then torture them. I found massive amounts of ghosts to work well in fighting the good. Plus its a lot quicker than waiting for the skeletons.

Cheat if needed, you can edit all the numbers and stats of everything in the game with a word processor.:) - [In the file "creatures.txt" in the "data"directory - red.]

Why hold back on the doors?
