SPIRITUS
Basic Powers
The Missing Voice: You may project your voice to anywhere that you can see, allowing you to perform feats of near-impossible ventriloquism and to communicate with others who might be otherwise beyond your reach.
Phantom Speaker: You may project your voice to anyone whom you have previously met, no matter where they are or how far away from your present location they happen to be. This allows you to speak to people over vast distances, as well as to create a stereo effect by projecting your voice to others while also speaking normally at the same time. This power truly projects your voice, and it can therefore be heard by others who might be at the same location as your intended recipient.
Intermediate Powers
Toreador's Bane: All Toreador already suffer from a clanwide weakness when it comes to art, making them easy to entrance with skilled performance alone, but this power allows you to cause the same effect in members of any clan, as well as in mortals or anyone else who might be listening to you. Those you entrance are incapable of ignoring or trying to interrupt your performance unless they are in direct physical danger, and are unlikely to do or say anything until you have finished.
Madrigal: You may cause others to feel emotions through your performance, instilling them with passions and responses they otherwise would never have experienced. You may choose any emotion to cause your listeners to feel, although it is generally much easier to make an audience feel an emotion that "matches" the song or speech you are presenting than to try to infuse listeners with calm while you shriek rhetoric at them. The emotion you create lasts only as long as the song or speech itself does, but it feels as utterly real to those affected as any emotion they might have felt on their own, and its effects may linger, depending on what they do or feel afterward.
Siren's Beckoning: Your voice is so emotionally overloading that it can cause mental instability in listeners, inflicting confusion or even literal madness upon them. You may use an appropriate song, speech, or whisper to inflict a random Derangement on your listener, which affects them for one full week while they struggle to throw off your eldritch influence.
Advanced Powers
Shattering Crescendo: You may create sonic blasts and high-pitched sounds so devastating and precise that they cause actual harm to the people and things around you, shattering glass, cracking fragile materials, and bursting eardrums in a sudden painful cacophony. Even if your scream isn't able to actually deal damage (for example, because your target has the Fortitude Discipline), it is still intensely painful to the ear.
Virtuosa: You may affect multiple people at once with your Melpominee powers, entrancing entire audiences, reaching out to speak to a multitude with perfect clarity, or blasting an entire area with painful sonic disruption. Your powers still work exactly as they did before; they just affect everyone in the area now instead of only a single target.
Elder Powers
There are very few elder vampires with advanced powers of Melpominee (or, perhaps, it is simply that those that exist are so skilled and subtle at using it that they have never been discovered). Rumor has it that elder Melpominee powers can cause so much psychological confusion and distress that they permanently drive their listeners to madness, or allow a vampire to suspend their voice to be heard in ghostly echo long after they have left the area.
Important Things to Keep in Mind
Melpominee is rare and strange, and most vampires probably can't identify it from its effects without prior knowledge (as a result, it is often mistaken for other Disciplines, especially Chimerstry or Dementation). While it is possible to create very flashy effects by using multiple Melpominee powers at once, this is extremely exhausting and taxing, and it goes without saying that it constitutes a major breach of the Masquerade.
