You'll need a horned reaper for this to work. Find a small hallway, and build two doors one square apart. Lock both doors, then place horny in there. Now summon or place level 1 imps in there. After you've slaughtered a bunch of em, put horny back in his lair, and then have your imps carry the corpses to the graveyard.

How to beat the final level?
