Honestly, I would like to get something different than an upgrade to our flute.
Personally, I think that a talisman which reduces lung qi costs and has a bonus to attack for lung based techs would be extremely helpful to us. 2/3 of our most expensive techs (AE, PLR) are lung based, PLR has a clash mechanic that would be extremely powerful but is not benefited at all by our current equipment, AE could use a good buff to make it's first tech hit people.
FSS and FVM both would benefit from it and with our passives to increase the difficulty of getting rid of them, as long as they hit it will be expensive to get rid of.
It would effect FVM, FSS, AE, PLR all of which are powerful arts, and also encompass our music arts.
Meizhen said that getting our offense up is what we need to do, and this is a perfect way to get a solid boost in our offensive capability.
