I had the most weirdest dream ever while I was taking a short-time(3h) catnap
after hard day at school. In that dream I got 'a steel chest (locked)' from a
monster which I killed and even managed to force the chest open. I opened the
chest and surprised myself completely after finding 'a book' inside it. Sure I
immediately decided to read it without any hesitation and was truly amazed
when a message (in a dream!)

appeared 'The books information taught you a
bit about skill 'cast harm'.' and then I checked my skills and there it was,
my 'cast harm' was raised by 3. So the main point in this is that these kinds
of Skill Books could exist, sure being EXTREMELY rare because one could be
able to learn a whole new skill depending on ones background. So if this
player is for example nomad, he/she wont be able to learn skill 'cast magical'
and he/she could be able to sell this book away to other players, of course
for high price. Sorry about typoes and the story being so messy, but maybe
this could create some thoughts in coders minds.
