So, I know there is a specified mana upkeep per mastery song. How often is the mana actually drained from you? (how many seconds in between?) Secondly, can the spells be removed from say...taking damage? Also, what increases the effectiveness of each song? Is it based on musicianship or peace/provo/disco? Or a combination of the two? I know you need a certain amount in both to actually cast it. I'm thinking in terms of how eval int is to magery or focus to mysticism.
