Our party did fight a medusa one time (a custom one though, with spellcasting, multiple forms, backup monsters, and a thousand HP)

She had a magical feather flapper dress that shifts and moves in an alluring way to show off your best features. It "gives you advantage on any charisma based checks that rely on your appearance"

She also had a large metal mask with animated medusa-like snakes, that you can use to make gaze attacks with.

Konsi now owns both of these.
