Why would one choose fortify magicka rather than fortify intelligence? Both of them increase magicka, but it seems to me that the fortify intelligence potions have additional beneficial effects, such as increasing your chance of successfully brewing potions and enchanting items.
Is there any significant benefit to fortify willpower potions? I see an increase in endurance but don't see if there are other benefits. Is it something that is best used under specific conditions, such as buffing before/during a fight?
Which would be more advantageous, a fortify agility potion or the sanctuary spell?
