Additionally, try to run from every odd battle between your first trip to Muse and reaching Radat, and trade Crystal Balls from elsewhere to the Kobold village and then buy up any Ancient Texts from those guys (if available) and make sure to take them to the Trading Town in the Greenhill region plus any Celadon Urns you come across can be useful for trading for potch as well.
More priceless nuggets of wisdom... I am taking notes my friend, thank you.
Additionally I remember you mentioning ages ago in a post about finding multiple squirels. As of now I only have Mukomo...errr.. whomever. Are these other squirels missable or just difficult to find?
