She sits down, and hums quietly.
"I think it depends on a lot of things? It's kind of metaphysically impossible for me to work hopecrushingly long hours on feeling hope, so there's that limit, for one. There's whatever use I'm making out of other powers - I can't do much more than maybe feed a little bit of power into things if you want me to be actively using a whole other powerset? I'm also not sure how much it's worth my time to use subpar materials, so I'll be kind of bottlenecked by my supply of that, too. "
Okay no you are being a silly girl who are talking about this like you are a machine with uptime concerns not a person with feelings stop ittttt.
She blinks and shakes her head.
"Frankly um, it depends a bit on how well I can monetize it and how well I can make use of money or opportunities to do good, have fun or spend money to make myself happier? I wasn't exactly rich in my old world so I don't have a great sense of that part of things. I do also want to - at least try to be a part of the team batman proposed? So time that I'm being a part of missions or other training is time I'm not working on this. I probably want to keep my hours... relatively reasonable, at least in terms of the emotional powers? The willpower ability means that I'm more resistant to those sorts of pressures then I would be, otherwise, but that doesn't mean that I can't be ground down. At a very loose guess, I don't want to be on the clock crafting or working on team stuff more than say... 10 hours a day six a week, and ideally we figure out some sort of formal 'on-call' schedule for emergencies? What makes sense for that depends a good bit on how well the lanterns and magicians can interact with what I'm doing and how important it ends up being, though."
She fidgets a little with her hands.
"Right now.... The warding pendants take maybe two or three hours to make, and making something as simple as possible is still five to ten minutes of reasonably intense work. Making a ring as good as I can make it is highballing it a bit a day's work, and that's about as big a project as I can do without it more being about experimenting and doing design and procurement work than actual execution? I think I can make most things fast enough that it's not too big a burden on me to create prototypes for a pretty broad set of things, but making any real volume is going to depend a lot on what batman and the league are looking for most, what big projects we can get off the ground, what's the best financially and figuring how much I can 'automate', tool up for or foist off on other people."
She does the air-quotes thing with her hands at 'automate'. It's going to be tricky, and probably there's no getting around involving a bunch of people in the process, but what's more important is being able to make it not the labor of someone who would otherwise be doing something as or more valuable than making it, rather than making it something clean and mechanically replicable.
