Mantle of the Black Masquerade

''They might be rich, but they aren't smart. Any gathering like this is bound to have people like you who weren't invited, who may have stolen an invite from somebody then dumped naked and drugged in a dumpster. You're here to find secrets, and hold them over those who uttered them drunkenly like a massive iron weight. You'll control them through blackmail, through a toxic cocktail of shame and deceit that you will freely dose into their lives whenever you see fit. You'll be their new master and live your life in comfort from their coffers. But first, the positively gorgeous man serving drinks to these idiots needs to be taught a different sort of lesson. This dress is so terribly tight and you'll be needing his help to get a little relief.''

The mantle grants up to ten minutes of flight per night

You have advantage on Charisma checks against nobility if you are anonymous.

You may cast suggestion, darkness, moonbeam, and nondetection at will. When both moons are full, you may cast maddening darkness once per long rest. All spells cast this way require no spell slots or material components and are DC 19.

By focusing on a particular humanoid creature, as if concentrating on a spell, you may learn a secret that weighs heavily on their heart. This is conveyed to you by the sound of a sultry female voice whispering in your ear. Everything she says is sexually charged, no matter how grim her confessions may be.

Legendary
The Mantle of the Black Masquerade is a relic that predates the Blighted Centuries. For several decades, a female figure would turn up at high class galas and balls in a fantastic black dress and afterward several high class nobles would spiral down into a path from which they could not return. At the end of Madonna Noire's career, a ball was held under the light of the swollen twin moons, the dress code of nothing but black strictly enforced. Despite the suspicions, the lavish decor, top of the line cuisine, and high profile performers of racy and elegant arts drew in all who were invited. Come dawn, all in attendance had disappeared, and the performers so horrified at what occurred that many of them never returned to ply their trade. The only thing left behind was this dress, the wings forming a delicate feathered shawl when not in use. The Mantle will teasingly deny any involvement in that night, but will describe in unerring detail what "might" have happened.
