In D&D 3.5, can wizards make use of potions with effects from their prohibited schools of magic?
Similarly, can they use magic items that give buffs or similar effects based on spells that are from their prohibited schools? For example, say they chose transmutation as one of their prohibited schools, could they wear a belt of giant strength even though that works off of Bull's strength, which is a transmutation spell?
This question doesn't include spell-completion magic items, which have been covered here: Can a wizard use wands and scrolls of spells from his prohibited schools of magic?
