Take your original character and loot the mines or buy spell scrolls from merchants. DO NOT read/use them though. You can use the shared chest item transfer trick to give them to a new starting character. Place the spell scrolls in the Shared Chest in town and exit to the title screen through the pause game menu. Start a new game with new character and go to the Shared Chest to retrieve the spells left by your other avatar. You can use these spells to arm your new character and/or your pet with magic immediately.
