Well, Auruentus, I'm not in your game, or the Restless Kaisers either. So my little "flight of fancy" is working with what "everyone knows". This board seems to have come to the agreement that 40+ for Arts and Techniques is the rational maximum, so I don't think that 30 is out of place or Legendary. As to the focus, it seems to be a "common" one, listed in the core rules as a minor focus. So there should be many Major focuses that include aging, yes? It's worse if you think about it. Potent Magic is a "Common" Mystery. Not a secret, and mentioned as something passed on from "Father" to "Son", not all the time, but often enough to be mentioned in the Virtue. So we can probably add Potent Magic (Major (Health)) to the equation and get another +6. And there is nothing in the rules, as far as I can tell, that wouldn't allow Redcaps to live in a Lab, and get a big bonus to Living Conditions. Maybe another +10 to the aging roll. Hard but possible. You would have to be rich and powerful. The Redcaps seem to be the glue that holds the Order together, and rich enough to give vis away as gifts for good magi over Christmas.......
Just some fun on my part. First as a thought experiment on Warping, and then as a campaign. Most of the people on this board are pretty arrogant when describing their mages. They're rich, powerful, no one is the boss of them! They talk of how easy it is to destroy whole cities! And yet, in canon, Mages really haven't done anything. Five hundred years of "gods" walking the Earth, and history hasn't changed? What's up with that? No reason is given in canon. I suppose you could explain it away with the Divine, but my darker spin on things has more story potential, I think.
