I just started playing this game and just cured Mardaneus of his insanity. I was wondering though, it seems that my character is needed to perform other quests. There are still quite a few skeletons and the like left in the catacombs. If I'm not mistaken, I believe there is another level as well. Should I forget about that, or go back to it another time? Seems a shame to throw all of those XP away.
