I dumped some of my army and hero onto Dungeon level 99 with a Guardian Stone... (-4 Ogres, -10 Throwing Axes). I finished it off with 3 Rukh attacks over the course of a day. In the Dungeon, Charna was level 5.
I was interested in the Grand Magus quest. The army consisted of 14 Ogres, 30 Throwing Axes, 13 Rukh, and 120 Skeletons. I was about to reach the 4th floor... I was checking out a box with 100+ Nomads right next to the 5th-floor entrance... Charna, Expert, Wisdom 3, Knowledge 3, Spells 3. The artifacts were a +3 Shield and that's it.
Thanks for the game.
