Note: The economy rating of the items is very important in your quest to find the rarest items. The items the seller sells are equal to or one star lower than the region economy, so, a low rated region economy means low rated items in the shops. To raise the economy in a region simply put the prices in your shops under 0% and each time you are awarded the money from your shops the economy will raise a bit; to lower the economy, just put the prices over 0%.
b) The Meteorologist - 50g
Bring all of Knothole Island’s weather problems under control, or help another Hero to do so.
For this achievement simply complete all three main quests (after completing a quest, go anywhere but Knothole Island so that the game gives you the next quest) and after the final decision the achievement unlocks.
c) The Bibliophile - 25g
Find all the books detailing the history of Knothole Island, or help another Hero to do so.
For this achievement you need to collect all of the 10 volumes of the Knothole Island books. They are very similar to silver keys. Here is their location:
Volume I – Given by the guy that brings you to Knothole Island with his submarine, when you first talk to him.
Volume II - Inside the Ice Shrine in the part where you need to hit 4 orbs to successfully stop the lighting, on the right there are some icicles that you can destroy and then vault down. Proceed to the ladder, climb it up, destroy some more icicles and the book is yours.
Volume III – Inside the Sun Shrine in the red floor chamber where you need to stand on a blue button to open a door, destroy the wall to the left from where you enter the chamber and the book is inside a small alcove shown by the broken wall.
Volume IV – As soon as you enter the Storm Shrine to the right in a small opening.
Volume V – For this one, enter Knothole Island and go to the ramp that takes you to the Ice Shrine. When you get there drop down (Sun or Storm Totem must be activated in order to be able to drop down). Go left and keep following the path. At some point you'll see some trees (usually you get attacked by Hobbes here) turn right and you should see the book next to a cliff.
Volume VI – Below the Warriors Rest House (left of The Box of Secrets) in between the bridge pillars (You need to have the Sun Totem activated).
Volume VII – Next to the west wall of the Sun Shrine entrance.
Volume VIII – As soon as you arrive in town turn left and head to the graveyard, turn left again and you can see the book in the middle of the trees.
Volume IX - As soon as you exit the Sun Temple, to your left, there is a book next to a dig spot.
Volume X - As soon as you exit the Storm Temple to your right.
