Might and Magic Cheats

After exiting Sorpigal, go S-W-3N-E-N-7W-4S-E.

You'll see a fountain you're only supposed to drink from once, and it raises a random attribute to 30 for your next fight. But if you bump into the trees ahead after drinking(enter), instead of turning around, you get to drink again. And again. Bump about 20 times and everyone should have all 30's.

You should then easily win the random fight W-S-E of this square, and there's another 30-boost fountain W-2S-E of that fight where you can reuse this cheat. Later you can fly and teleport to even tougher fights.
