1. I found the game was of ok difficulty (I was using a bow at the beginning and everything took forever to kill...) until a boss I had to kill would constantly 2 shot me with exploding arrow before I even got close.. then it was too hard frown and I swapped to easy mode to kill him.

2. Weapons seem to have melee damage and magic damage, what that means exactly I have not really bothered to find out >.>; but that could explain the difference in price

3. Later in the game I was 1-shotting groups of enemies with explosive arrows :[ I think at some point in the higher levels I crit for ....over 9000! (really)

4. It is possible takes 5000/10000/20000 etc to respec, never went past that price.. you will get the ability to both respec and bump up the level cap of abilities when you find a trainer later on.

5. Books in the misc section I've never found a use for, the only books that I've seen with a use will either appear in your quest items, or your consumables (skill books)
