Might & Magic VI: The Mandate of Heaven [hints]
Get 9,999,999 Gold Pieces Easily
When you find the location of the lost hoard of the obelisks, the treasure includes 250,000 gold. Open and close the location or chest it's at before leaving the location and the gold will increase by 250,000 gold pieces every time. Repeat this until you have 9,999,999 gold pieces.
NOTE: This trick relies on a bug in version 1.0. It will not work in version 1.1 or later.
Free Skill Points
Go to the stables of New Sorpigal. At stables there is a covered wooden walkway. Inside the walkway there are two horseshoes. Use the horseshoes on a character to give them 2 skill points for each one.
Free Fly Scroll
In New Sorpigal you can get a free fly scroll by going to the south wall of the bank. Note that this relies on an error in version 3.1 or sooner.
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.
