After playing Wizardry 8 for awhile (produced by Sir-Tech Canada Ltd - see Links section), I was continually finding spellbooks and being offered them from merchants in the game, but when my spellcasters would try to use them, would get this message "Bloggs is not powerful enough to understand the writing". Then I found an old message that had been posted on VN Board's Official Wizardry 8 Board by one of the Wizardry 8 programming team (Alex Meduna, Wiz8 Lead Game- play Programmer / Designer), I got the idea to make a spreadsheet to do the calcuations for me.
