I know about nymphs and succubi, but is there any other monster in the lore that is extremely beautiful and humanoid-like or similar that seduces people?
Even a high-Charisma humanoid monster would do. The more exotic looking the better.
I am looking for humanoid entries in the monster with high-charisma/diplomacy skills; the lower CR the better, the more exotic-looking the better. Bonus points if the entry specifically evokes a great beauty or good artistic/social skills. Fey are okay, but non-native outsiders may be a problem (in other words, I'm looking for something that can be found on the Material Plane).
