With Vanity add a little extra

on body and leg armour i was hoping we could have a dedicated slot to attach items, for example a flower or a jewel, sorta like the FC emblem thing but something of our choice (within reason of course) just for soul vanity reasons, no stats just looks.

this could also be a trophy thing, where upon killing a big boss, depending on you ranking within the fight, and random chance you could get the heart of titan to place on your chest, as a show off item, which glows yellow, ifrits flame which makes one arm burn, or garudas feathers as shoulder guards, with a quest to attach a so called item. (i'm just using primals as examples because you dont really get to use their weapons as long as you'd like to)

Just a thought, i thought i'd throw out there
