A handy chart from Jarulf's Guide. This lists the magic required to read every level of spellbook in Diablo and Hellfire. The formula is very simple: books have a set amount at level 1, which then increases 20% per level. Any values over 213 are automatically set to 255. (The initial amount is also how much mana the blue bulb fills up when a character reads a book of that type.)

In Diablo, Rogues and Warriors can not achieve 255 magic no matter what equipment they assemble, (Rogues can get to 245, Warriors to 225) so can not read higher level spellbooks and must hunt for [[D1 Shrines|Enchanted Shrines]] to boost their spells to 15. In Hellfire all of the characters except the Barbarian can get to over 255 magic, thanks to some of the new uniques. (All except for the Barbarian, who maxes out at 235. See all the [[Diablo_Characters#Max_Stats_with_Equipment|max possible attributes here]].)
