Note: You need to obtain the Ship, defeat Lich and obtain the Healing Staff & Gauntlets from the Citadel of Trials before attempting this.

Set your Cursor settings to "Memory." Find a location between the north and south continents heading east to west that allows for uninterrupted, around-the-world sailing. Fight one battle having your Melee character attack, character with highest Intelligence using Healing Staff, and the 2nd highest using Gauntlets. (Optional) Once this is done you will notice holding down the X button will auto-select the same choices for you. Use something (Tape? Rubber bands? Bubble gum?) to pin the X button and LEFT or RIGHT down. Your party will now auto-fight and heal itself every round. Check back if you begin at a really low level as you MAY die. But you shouldn't. Happy auto-leveling!
