Today I finished the game. I only got to level 58, barely... I guess 2 +5% XP items and 10 Ancient Knowledge scrolls were not enough. If I had not played this as a relatively quick no-loss warrior game (no casualities, 13 days, impossible warrior, 1747 points), and had gone kiting in the beginning, I might have reached level 60. The reason is that I found 2 Hands of Necropolis in Nameless. But by then I already had completed the Ogre Set and had the new Jimmi Kraud as my companion, so there were no room for them. Also, the only areas that remaind in addition to Nameless was Sheterra.
But I achieved level 60 for my Pet Dragon, which is nice
btw, My Ogres did well against Baal. They crit'ed for 15K when raged and took only 50-100 in damage in retaliate. Nothing spectacular, but quite ok. They did better than my Paladins that also attacked Baal. My Paladins did only crit for 10K. My final troop was Inquisitors so that I could ressurect my two lost Ogres after the battle. My Leadership was 52K which is quite high, I think.
