Shouldn there be a die roll for non-fatiguing spontaneous magic?
No. The rules on p. 81 are correct and are not a misprint. Non-fatiguing spontaneous spells are magical effects a magus can produce safely, easily, and consistently. If there were a die roll, it would encourage players to cast their non-fatiguing spells over and over again, hoping for a lucky die roll to get an unusually powerful effect.
