Go to Eregion after you get the Craft Item Stone. Then, find an Archer. Cast Fellowship Grace with Berethor and the Haste Of The Elves ability with Idrial on whoever has the Craft Item Stone equipped. You will never run out of AP, and the character creating items goes very fast, producing a lot of items. This is especially useful for the Elf Medicine item. Also, you can level up character abilities that do not damage foes.
