Is there some errata for the Magic Memory virtue from the ArM5 main book?
As read it seems rather weak, in that it does not acknowledge your exposure to your parens' lab notes and lab activities.
By that, I am assuming that the majority of apprentices will at some point in their apprenticeship assist their parens in the laboratory, and/or be required to copy lab notes and other documents involving lab creations.
So I was expecting that a just-gauntletted magus with Magical Memory would go out into the world with the equivalent of a certain amount of lab notes from their parens.
Say the equivalent of 60 levels worth of spell creation/enchantment lab notes, that can be decided by the troupe (and if you are really generous, decided after character creation). Perhaps Skiiled Parens and Weak Parens might change this, say +/- 30 levels.
