Ah, another instance of "not our mistake." Both Ulf's and my memories are correct. The discrepancy is in the books and which parts we happen to remember better. I'd actually rather have been mistaken entirely, but it is what it is.
No, it doesn't seem to. I don't see how having that happens needs to cause the exclusionary practices in the definition you quote. Without such exclusionary practices it would not fit the definition you present. I'm not saying such a character wouldn't have a significant focus; I just see no reason it has to come at the expense of everything else.
But doesn't that pretty much fit one of the two main ideas of the Cult of Heroes? The other would be a CrCo specialist. These rituals are the ones that show up in that cult with Mercurian magi. If you want to make a very canon-styled Cult of Heroes magus, wouldn't you tend towards that anyway if you chose a Mercurian?
In our new saga we had a brand new player who wanted to play an incredibly good healer and so is playing a Mercurian focused in Creo. He also wanted to be good at longevity rituals. The focus he asked for (I forget the wording, but somehow more Corpus-focused and less healing-focused than "Healing" because he only wanted humans but wanted to include longevity rituals.) applies to the physical stat improvement rituals. These rituals are practically handed to him, and he didn't even know they existed when making the character. (See below for how little Lab Total is actually needed to get there.) This player is able to do it without that being his intent.
Yes, therein could lie a problem. That's why I believe the stat-boosting rituals along with other canon descriptions seem to be at odds. I'd commented elsewhere that a duration of "Real" or something like that one or more steps above year to be used in place of Momentary for Creo rituals would help fix a lot of things. That would push these levels up a whole bunch of magnitudes.
But maybe that's why all magi seem to have Int+3 or higher? Of course, where'd the warping go? And why stop at Int+3?
I would, however, do all that just after apprenticeship begins so that only a Bonisagus could take my apprentice instead of anyone who wants to. Hmmm... maybe people stop at Int+3 for fear of the Bonisagi.
I could see a peripheral code ruling about not overly warping apprentices after some magus had given his apprentice a warping score of 2 or 3 and the former apprentice botched and hit a massive twilight episode (botching the control) shortly after his gauntlet, too. Oooh, fun!
But there's still Direwolf's and Richard's points about obsession. All we really care about is the few magi obsessed with writing. You only need around 1% of magi to really want to write well and use the rituals, and the effect will be there. That was my point about the steroids. Most people won't use them. But those who are obsessed with something have a tendency to push the limits, even when it comes with consequences (warping in the case of the magi).
Not according to ArM5 p. 112.
Yes, I did have an Affinity w/ Magic Theory. I can't remember if I had Puissant Magic Theory or Inventive Genius. And I'll say that at the time I did it there was no Magic Might penalty to learning; it was prior to RoP:M. The familiar and I read alongside each other, her Magic Theory and me other things. I also had an Affinity with Mentem and Good Teacher.
You could offer a good lab rat magus to tailor the spells to him to prevent warping and let him and his familiar be included for free in the rituals. (This is what my character was doing.) You could even offer a small percentage of the profits. That can be worth a bunch of seasons, and if the magus has enough desire to go through the rituals that can deal with the social stigma. Now you have three assistants, and potentially a fourth with an apprentice. (I'll not use an apprentice below.) That could easily add on the order of 20 points, but let's call it 15 figuring the Int's will roughly cancel leaving you with two MT scores and some lab rat virtue. (Especially when your Good Teacher has been teaching them Magic Theory in group classes alongside your own familiar.) Your leadership could limit you here, but you don't really need a lot. There's another biggie: you can work on your laboratory. You can spend 2 seasons for a +5 using a greater feature/focus. You can get some Co/Me bonuses for free from Persons/Servants. So an investment of 2 seasons could get you to the order of +10 in your lab. You don't even have to be the one adding the feature/focus, so that can happen while you're studying; it could be your apprentice or your familiar or some other assistant. You could certainly add more to your lab, too. A lab total of 68 gets us the level 35 version in 1 season (with routines) for an extra +7. Now we bring in the other magus and his familiar to get to 90, so we only need them for 2 seasons to get the level 60 version. You'll need Leadership 1 with an appropriate specialty. Or does your familiar add to that necessary Leadership score? Still, that would only be a 2.
3 (Int) + 6/7 (MT w/ specialty) + 3/2 (Inventive/Puissant) [or this could be 9 MT w/ specialty from affinity] +5 (Aura) -3 (Familiar Int) +6 (Familiar MT w/ specialty) +10 (lab) = 30. That leaves Cr+Me of 38, so 19 and 19, perhaps adjusted if you have Puissant and/or Affinity. And don't forget Leadership 1. (Note, we can still shave down the Cr+Me with some more seasons put into the lab.) I've used much more reasonable Int and MT values and have still dropped the Cr and Me requirements drastically. This is potentially not very far out of apprenticeship at all; it's very doable in a decade for a Cr or Me expert. (You don't even need to focus in both.)
I forgot to reply about this one. I really like the idea of tractatus having levels. I think it would improve the flavor of things, such as with your Old Llywellyn example. It's also a very simple idea to implement, making it even better.
He did take that into account. There were actually a lot more books in existence, and the situation given was that the book trade (of like tractatus) was done very regularly. The number 20 wasn't 20 in existence but 20 obtainable from nearby with frequent trade existing.
Me, three.
