What spells could Isa be used to enhance, and in what ways? There were many different aspects of the rune to be considered- blockage, patience, concentration, suppressing the emotions. It could be used with any number of spells. Did it only work to enhance spells, or could it enhance other things, like potions? Rather than just list another spell that it might work with, Penelope decided to ask her question. "Professor, you said that runes can be used to enhance spells, but can they also be used to enhance potions? We learned how to brew this potion in potions class that could be used to manipulate people by making them feel guilty. The potion is not as effective if the person's will is strong. Could Isa be used with this potion to suppress or block the emotions, other than guilt, of a strong willed person to make the potion more effective on them?" That would be interesting to experiment with if Isa could be used with the potion. Maybe she could get extra credit if she tried it. Even if she could not get extra credit, it would still be interesting to try, with supervision, of course.
