There have been a couple of Spell Books that I have found that are useless for some reason. One is called 'Sparks', although it has the same picture as 'Elemental Something or other'(I can't remember the name, sorry), and the other is called 'Heaven's Something or other', but it gave me a level in Magical Might(is that what it is?).
Also, a couple of times I got an Elemental Hail book, but when I clicked on it I was given Hell Spikes instead.
Anyone know why some of the spell books are screwy?
