The wings would be crafted from string and butterflies. They could be equipped so we could larp as pretty fairies. They could give something like a charisma boost since fairies are very charismatic.
Butter-flies would be a new curio crafted from butter and dragonflies (or maybe midges, if we can catch them one day). It could also be used as an alternative to normal butter which would cause damage because eating flies is gross. Yeah.. I like bad puns.
