Aile Starlight changes the appearance of my soaring blades as well as my double saber.

The description only says it should change the appearance of the double sabers

EDIT (I'm seeing it has attack animations for both weapons and they're unique, so guessing the description of the item just needs to be corrected to say it modifies both soaring blades and double sabers)

a lot of weapon camos have wrong descriptions when is applied for several weapons this is not the first one to have that issue

it camos soaring blades and wands too i think

Yeah a lot of the new camos have incorrect descriptions for some reason.
