I am pondering a house rule to change how the source quality of books is calculated. What I find odd is that the virtue Good Teacher increases the source quality of the books you write, but your teaching ability doesn't matter at all (unlike for seasonal activity "teaching", where Good Teacher also applies).
From an earlier thread discussing a similar idea (Rule Variation for book Quality.), I took several comments:
-Using the straight Teaching ability results in an increase that is too fast.
-It was proposed to use the lowest of several abilities (Teaching and Artes Liberales, possibly also Philosophiae) or a fraction of their sum. I don't know any other total where this is done, so I would reject that idea as too complicated/not in line with the other rules.
-An argument against the whole idea of basing quality on teaching ability was that characters without a decent teaching score may be less interested in writing. I'd argue that tractatus of quality 6 or 7 are not too useful, so if you can't get to at least quality 9 or 10, then you will not write too much anyway. If you get to quality 9, then you already have either high Com or Good Teacher, so you probably already have some teaching ability. You only need a teaching score of 3 to get a +2 under the house rule (see below).
Therefore, I am thinking about replacing the flat "+3" in the calculation (using the extended rules from Covenants) by "+ (teaching ability)/2" (rounded up, as usual). This way, with a teaching ability of 5, you get the usual +3 bonus. Now, I'd like an opinion on whether to cap that at +3 (to keep the original quality scale more or less intact), or omit a cap, allowing potentially higher qualities than previously possible.
More precisely, the question is: do I change the calculation of a tractatus (and summae, in an analog way) source quality from
Author’s Communication + 3 + bonuses for skilled artisans, mystical resonance, and virtues to
a) Author’s Communication + (teaching ability)/2 + bonuses for skilled artisans, mystical resonance, and virtues, or to
b) Author’s Communication + (teaching ability)/2 (max. 3) + bonuses for skilled artisans, mystical resonance, and virtues?
Let's assume that someone who cares about passing on knowledge will have a teaching score of 5. Then, getting an additional +1 over the current rules costs an additional 65xp or Puissant Teaching to get teaching from 5 to 7. For +2 it's 65xp plus Puissant Teaching to get teaching from 5 to 9. For +3, it's 150xp (alternatively, Affinity with Teaching and 100xp) plus Puissant Teaching. So it seems that getting to a quality one point higher than under the current rules is not too hard, but getting much more is quite costly (but possible, if you really lean into it).
How big would the effect of omitting the cap be? Some arguments for (+) and against (-) omitting the cap are:
- It seems fair to reward high ability when you "punish" a low score.
- With Affinity and Puissant, high teaching skills are possible, but is that really worth investing in those virtues instead of others? Good Teacher gives you +3 to quality, are you going to buy Puissant teaching on top of that just for the +1?
- It would make the creation of specialist (minmaxed) companions more attractive, but we mostly care about books on hermetic abilities and arts.
- Covenants also caps the bonus from a lab's Teaching specialization at three, so that could mean a cap is a good idea.
- Circulating more powerful books does have the potential to change a campaign.
Any opinions? The goal is to tweak the rules a little without upsetting the power balance.
