Below is a guide from x360a.org, I take NO credit from this guide below:-
NOTE #1 If the books aren't there when you go to the Book Store, try again later on in the story, please don't ask, "why isn't this there?". The appearance of books seems to be random. Try buying everything and then going back later if all else fails.
MAX OUT STRENGTH, WILL AND SKILLThis is a lot of grinding, if unlike me, you have the Temple of Light still available, sizeable donations could help speed this process up. If not, try and buy the Thunder Strength Potion, Expert Skill Potion, Undiluted Will Potion and the Pure Experience potion for around 10,000 gold, but they give you 62k experience each.
If you are unfortunate to have stepped down the road to darkness early on and have no Temple of Light to donate to, then a good strategy is to buy a Thunder Strength Potion, Expert Skill Potion, Undiluted Will Potion and the Pure Experience Potion from the Bowerstone Market Alchemist and then run to the inn (or your house) and sleep for a week. You must have gold to burn to do this though
Before you give me a negative vote, please explain yourself why you did it and I will be more than happy to improve my solution. Thank You.
