How do you use books?

do you get to learn spells?

u can learn spells from magic books by right clicking it . there will be an option to learn(invoke) it. hope it helps

The invoke option is only available if you are currently capable of learning that spell. My paladin is level 9, with level 7 spirit and level 6 vine. I have a couple of level 5 vine spells, but will not be able to invoke them till I get to level 10 (ie my paladin can only pick up the vine spells till level 4 at present - half level value).
