Defeat Balkoth Easily:
Use the map editor to make a map. Erase the Life lord and place a new one beside Balkoth. Save the map and load the custom board. Use the Infinite Defense code to make yourself immortal. Then attack Balkoth and kill him the first turn. Game over, you can now play as him under any setting.
Choose your following as a Life Warrior, you'll get the Peacemaker as your artifact. If you take the staff out of your hand and put it back in, your defense steadily increases, permanently. Works only on Life Warriors and Mages, not Thieves. It's a game glitch.
