I'm glad I did as some things I learned are important. The main thing being that when you cast the spell it doesn't only take a large amount of magic but also takes a large amount of magic to maintain the spell. So you only have around half a minute to write down the results before the magic runs out. The second important thing is what the spell actually does when you cast it on somepony of yourself the spell's matrix will have several balls of light each of a different element.
