Whether the Jewish Lilitu or the Arab um al duwayce, the core idea of the succubus or incubus is the same: a demon or spirit possessed of beauty that is used for malevolent purposes. Their beauty is darkened inevitably by something that happened to them in Faerie, and this hangs upon them in some way that colors their splendor with hints of the diabolical (blood-red eyes, bat wings, black nails, teeth filed to points or other demonic characteristics). These changelings are temptresses, creatures who are imprisoned by lust but can also wield it like a weapon.
The Succubus and Incubus gain advantages from Vice to Vice: if another character has the same Vice as the Succubus, the Succubus gains a +1 to all Social rolls when dealing with that target. If the Vice shared is Lust, then that bonus is doubled, becoming +2. The Succubus and Incubus also gain the Striking Looks Merit for free at two dots; if the Succubus and Incubus already possess the two-dot version, then it increases to the full four-dot version.
