Alright, I know all available lore for all this kind of stuff, but I would like to know one thing. Massivecraft Magic has limits, the larger the spell, the greater the toll on the caster, like in Eragon or other books, but with the side effect of possible possession by void demons. However, what constitutes large spells? It goes without saying that something like using sparks to light kindling or a candle is simple magic, even a novice can do that several times over without getting fatigued, and that something like drawing fire from the sun is Godlike, and over the ability of anyone ever. However, what is in between? How much power does it take to produce and manipulate a fireball from a candle or flint-and-steel? What about producing an air shockwave? What is the formula for energy required to do magic, and how much energy does a magician have? What is the rate at which one gains energy, giving an estimate for relative ability of magicians? I would like the answer for this question, to help magical roleplay.
