Hello all, me again with another question on shifting and changing Ars Magica.
Before I actually get to my question I would like to provide a note on why I keep on asking various questions that seem to basically be a wish to break the system and change the entire game's philosophy. I am a GM/ST/SG at heart, I am a storyteller who works best by analyzing certain facets and figuring out ways to twist them into other concepts. Some of my questions have been directly related to something I might want, while other times they are just a "hey is this a nifty thing" sort of concept, which I would never actually implement in a game.
This particular thread is presenting an ability for Hermetic Magic to effect, control, and create 'Fate'. In a mechanical sense I am considering Hermetic Fate to be similar to the Fortunam Art of the Learned Magicians in the Hedge Wizard book. And why the book itself says that this is not directly accurate, I will use the idea that Tueor guidelines are similar to "Rego", Succurro guidelines are like "Creo", and Vulnero guidelines are like "Perdo. With all three arts being related to the category of Fortunam.
Now, I am not interested in creating a sixteenth Hermetic Art, I like the philosphical balance of Five Techniques and Ten Forms, I think its pretty cool and pretty sweet. So, if I was to allow 'Fate Magic' to be a part of Hermetic Theory I am going to try and find a way to fit it in with the various Arts that already exist. Also as a thought, though I am not against story ideas, i am not going to present story seeds, adventure thoughts, or even breakthrough rules for providing fate magic to the Order. This is more of a sort of after the fact point.
My idea is not to have an actual 'Fortunam' Art but rather roll in fate magic into the other ten forms. The concept is that the Art in question is who the target it. So, as a very base example, to do something like "allow a player to re-roll a failed roll" I would use the base Level listed in Tueor Fortunam and I would have it be a Rego Corpus magic, since a mage is part of the Corpus art. Even if I was to have this sort of magic be a breakthrough or whatever I would probably add +1 or +2 magnitude for unnatural activity, but still.
Besides the question of is this even theoretically make sense, I really want to know if such sorts of magics division actually occurs in Hermetic Theory. What I mean is, its not what is being done but its who is being done with it that matters. It would add a bunch of new guidelines, but it adds them to existing Arts. I think it could be kind of cool if modifying and expanding Hermetic Magic in this sort of way was in theme in certain senses to greater Hermetic Magic.
I would really enjoy hearing others opinions on this thought experiment.
