She finds two minimally useful divinations in the hour she's allotted to this project, and she takes an extra hour to wheedle them into knitting together, infusing a spare lens, and accepting power from the marble and only when looked through instead of from the staff and continuously. She puts the new lens - now a dark amber color - on the arm of her spectacles, and tests it out. Yes, she can see the staff calling for magic and her protections and the forest denying it with enough gentleness that it doesn't simply die. She feeds the staff a little personal witchery - she doesn't want it to die before she can really get to work on taking it apart - and then wraps it up and puts it away.
She goes looking for Tony.
"If you have time, I'd like it if you'd work with me on a new lens for my spectacles. I've been fighting with a dwarf spell intermittently for weeks, but I'd like to have it ready in time to go along with the delegation who's going to check out that wizard colony and get a better look at what's going on there, and I think your help would speed things up."
"All right." Bella pulls out her notes on the spell - she's got a primary source on the original spell she's adapting, lots of material on putting seeing-spells into lenses in general, and then a lot of incoherent ranting at her notebook about the stupid uncooperative dwarf magic. "I recently had the idea of trying to enchant the frame of the lens - the iron bit that wraps around the glass - instead of the glass itself, but I don't even know where to start," she says, pulling a blank lens from one sleeve and putting it on top of the notes.
That doesn't get quite the desired result, and neither do the next fifteen variations, but by the end of a highly fun afternoon spent messing around with the lens, Bella clips it onto her spectacles, gets all the other lenses out of the way, and declares it, "Satisfactory!"
Bella gets out her moccasin pattern and has just started marking where she'll need to cut when it occurs to her that it's dinnertime, and she's probably allowed to eat with her fiancée's family.
She goes down to the kitchen, since she knows where that is.
Between dinner and desert, Bella ventures to say: "Your Majesty, I was able to get some divinations out of the wizard staff and put them into a lens, and Tony was able to help me finish a dwarven lens as well, so I'm a bit ahead of schedule. After I finish my new pair of moccasins, probably tomorrow midday, I was wondering if there was any chance I could have a look at the sword?"
