I was trying to decide what to do with my 75 build points, and taking a good look at buying a Bookstand of Hespera (Covenants p.121), and I suddenly realized that I may well be able to claim lab bonus for my talisman: I designed it to be helpful for a scholar, but that would neatly carry over into laboratory bonus (as per Covenants p.121).
Here are the effects I have:
Thoughts Distinctly Burned, ReAq 20 (writes words as Diotima speaks them). A +2 bonus to the Text specialization seems indicated
Chamber of Summer Breezes, CrAu(Ig) 20 (keeps the air warm and dry). Magical (Superior) Heating virtue (+1 Health, +1 Aesthetics, +1 Ignem)
The Welcome Addition of False Sunlight, CrIg 20 (creates light). Magical (Superior) Lightning virtue (+1 Aesthetics; +1 Texts, +1 Imaginem)
Hide to Parchment, ReAn 20
Binding the Mundane Codex, ReAn(all) 15
Not too sure about those last ones. Sure, they help in creating books, but that's hardly a laboratory activity. I might be able to claim a -1 upkeep for the first one, but that's probably better used as a covenant cost-saving device...
