You should end up in a long hall which curves around. Turn right and destroy the books that attack you with Flipendo. There is a pot in between that gives three Beans. Then, turn around and you should see some suits of armor. Next to them are there is two shield-like objects (they resemble an award) and one pot, each positioned in between the suits of armor. There are four suits of armor. Each pot and shield when Flipendoed give out five Beans.
