Let's see, other hints that I can give you. Ah, don't take any wooden nickels. Seriously, try to give your party the best armor you can give them. Use the moonstone to zoom around from place to place, it's the fastest mode of transportation.

If you're inn a really tough dungeon, turn everyone invisible and just walk through, get the treasure, and get out...I did that in the dragon's lair. Got tons of treasure and killed all sorts of dragons and drakes...and they never saw me coming.
