Auron looked once more to make sure he didn't look it wrong. It was a super rare item. Even Auron never found it before.
The seventh and last item was a book. But, it was not a skill book rather, it was an attribute book.
An attribute book was a rare item. However, it was not impossible for a player to earn it. Also, the effect of the attribute was variate among one book to another even they have the same grade.
The grade only determined the minimum number of attributes it would give. Meanwhile, the attribute given would variate. There were books that give only one type of attributes. There were also other that give a number of mix attributes.
And, the most expensive one was the one that give a free attributes point which player could allocated it themselves. This was the one that was on auction's list Auron received. Moreover, it was a king grade which mean it would give a minimum of 200 free attribute points.
