Get a hand fan. Bai could never talk down on that, it gives us an instant plus ten in high society lady points.

As for talismans I think we should get something more generally useful and personally fitting. We don't want to get a specialized talisman and then a few months down the line find that we've filled the gap in the build and made the talisman kind of redundant. A social talisman for instance is useful in our current situation but in a year when we have three full social Arts we'll probably look back and wish we'd gotten something more in line with Ling Qi's more consistent priorities.
