Might and Magic 6: The Mandate of Heaven Cheats

Get Better Weapons, Items, etc.
Power Liches, Dragons and Veterans will drop high-level items 30% of the time. So kill one and save your game before checking their body. Search their bodies and restore your saved game if a valuable item doesn't come up on the search. The item in the body will change everytime you restore your game.

Maximum Use of Wands
Use a wand until the charge has only one left and sell it afterwards. You will get the same amount of gold as if the wand was fully charged.

Tons of Experience
Do the 9,999,999 gold trick and go to the town of Kriegspire. There is a well this town that gives 5,000 experience in exchange for 5,000 gold. Since you have so much gold already, you can raise a ton of experience for all your character.

Tons of Experience 2
After finishing the Fire Lord Quest (removing the curses), and talk to the Fire Lord. Keep clicking on "Quest" over and over (you'll hear the Exp sound every time you click it). Do this for 5 minutes and you can get at least 14 million experience. Click "Done" when you are finished, but you can't go back.

Use the "Shrine of the Gods"
More Than Once When two or three people in your group are dead go to the Shine of the Gods. Go to turn-based mode near the shrine and heal one of the dead characters. After the monsters end their turn click on the shrine and you get +20 to all your stats. Heal another one of your characters and he can also use the shrine. Repeat for third dead character.
