Ok, sorry in advance for the noobish question but there must be something im overlooking.
i have a level 16 bishop in my party. his wizardry skill is 54 and divinity skill is 52. his air skill is 39 with 125 sp. his divine skill is 76 with 204 sp. i have 3 spellbooks that he can not use (it says he is not powerful enough to understand the writings) they are set portal, return, and heal all. Am I missing something here? Why cant he use these spellbooks? Its somewhat frustrating.
