A Look at Monster Book

This is of course assuming the book levels up in equal steps, which in my opinion is unlikely, I mean, nothing else does (characters, pets, mounts, weapons) Why should the book?

Yeah, we established that :p

I'm trying to work out how this leveling works now... There's 8 different covers, and since it starts at level 1 that means it can level 7 times. In the first incarnation of the Monster Book, there were 297 regular cards, which means if the leveling requirements were equal it'd take 37 cards just to get to level 2... Since mine was level 3 at 33, that's clearly not the case. If someone wants to try to figure out some sort of leveling equation based on that information feel free, but I don't really know where else to go from that.
