Alchemy Books (I, II, III) increases the compounding products max rank by one.

I added Alchemy Book I to the items. I didn't add II & III because I don't know the text on them.

I tried adding a compound for Bronze Triedent (Bronze Boots + Black Jade + Alchemy Book I) but the site wouldn't let me add it because the math didn't work out.
