I don't necessarily disagree because it's hard to price things when we have so little market data, but we probably need to keep in mind Xu Yun was performing charity
We need to price based on what the 9th Circle can afford since they're the ones it makes any sense for, and 50 points is a lot. That's like ~15 talents: significant money even for someone of our social standing, and will those above really buy a second-hand charm and not a bespoke commission? Something like 30 seems more comparable to what a basic tech costs if I remember Peng's visit correctly. A charm has the advantage of being available immediate without training, but then it also gets outgrown so that seems a wash.
I might be too optimistic, but this is the relevant quote for selling charms:
Once you have reached the Eighth Circle, you may sell any excess charms you may have with the help of Ma Heng as a free action. You will set the price yourself, but if there are no takers, Ma Heng will gradually drop it week after week until someone takes it off their hands. For this service, Ma Heng takes a 20% commission.
So it's better to set an initial higher cost if we don't need money the next two weeks.
I'd rather buy it sooner than later because we have an issue holding on to money once we go shopping.I agree with this, but I'll note that "next" doesn't necessarily mean "immediate". We already have three techs we need to integrate. Adding a fourth would divide our efforts far too much. That's not a problem though — waiting more time means we can save enough money to buy an actually good tech. As we've seen, even the cheapest techs are expensive, so getting one that comes close to the options Siani gave us is going to be expensive (and no, I'm not claiming we can match a tech from an elder, just that we want to come as close as we can).
I don't think we should be too worried about the initial dice and grade of the techs, since they can get upgrades after integration and IIRC higher Grade techniques is harder to get insight for.
Grade 2 should be good enough. Dunno how expensive it'll be but our allowance is coming in a few weeks, and if we put VR up for sale next week too, we should have a good amount in about 3-4 weeks?
