Just a question. Do you think that ceremonial and spontaneous magic should be affected by the same virtues and flaws? On one hand they are very similar but there are flaws and virtues that affect spontaneous magic but leaves out if it affects ceremonial magic. Tell me what you think.
I'd rule that they do, except for the mastery ability that allows a formulaic spell to be cast ceremonially. The underlying spell, after all, is still spontaneous, just cast more slowly.
