If three groups of thieves escape, you fail. There's no harm in letting two escape to give you more time to complete challenges.


I recommend leaving a portal on the lower left, middle thief lane so that you can get down there to intercept thieves from your dungeon heart. This area has quick access to the upper and lower lanes as well.


"Treasure Hunter" and "Gold nose" are one in the same. By treasure, it means the 12 little bags of 100 gold spread throughout the map (but not in the thieves passages). The bags must be picked up by the Dungeon Lord because they are ignored by goblins even if your influence covers them. Location of the bags:
3 x lower left corner by the thieves passage.
1 x by the healing fountain
1 x by the hostile pentagram (scorpions) on the top left.
1 x by the hero gate to the left of the dungeon heart.
1 x by the Amoeba to the south of the dungeon heart.
1 x just south of the pentagram (flying snakes) to the top right.
1 x by the hero gate to the top and slightly to the right (left of flying snakes).
2 x by the hero gate to the right and slightly down.
1 x by the hero gate to the right and slightly up (below flying snakes).

The white dots on this picture mark where the 10 bags of 100 gold are for "Gold nose"

Despite many attempts, I have not been able to get "At least he's still groaning." I've finished it with his health at ~10%, ~80%, and ~90% but it hasn't triggered. I think it's bugged.
