Succubus/Incubus Heritage

The Succubus/Incubus rely on charm and manipulation to gain power and influence as opposed to the sheer brute force employed by many other devils and demons. By some quirk of nature or magical experimentation, their exploitation of a humanoid's lusts has, in rare cases, led to offspring. This demonically charger blood manifests itself primarily in ways that Charm foes without detection and creates a mental link between Sorcerer and thrall. Since by nature a Succubus/Incubus is a "lover" and not a fighter, this ancestry also provides magics the protect the sorcerer or cover its tracks. As these powers reach their limits, the increasing flow of magical energies results in the Sorcerer being able to manifest a form similar to that of a  Succubus.

Fiendish Magic

As your power grows you gain access to abilities, similar to that of your charming fiendish ancestors, that manifest as sorcerers spells that come to you without practice or study. Because these powers stem from your nature, these spells do not count against a sorcerer's typical capacity for spells know. These spells can be replaced as per the normal Sorcerer rules but you must choose spells a spell of the same level and it must have either a Charm effect to be fire based.

Origin Spells
Spell Level	Spells
1st	Charm Person
2nd	Calm Emotions
3rd	Vampiric Touch
4th	Fire Shield
5th	Modify Memory

Development Notes:

1. Charm Person: This is the one spell on this list that is already available to the Sorcerer, but thematically it this almost identical to the Succubus Charm ability which is fundamental to a succubus.
2. Calm Emotions: Being that a Succubus desires to operate on manipulation instead of brute force, a spell that allows the the sorcerer to defuse a threatening situation or leave create leave a small riot in her wake to cover an escape seems to fit perfectly on a thematic level.
3. Vampire Touch: This spell is a near perfect thematic match for the Succubus's Draining Kiss ability.
4. Fire Shield: Since a Succubus is a "lover" and not a fighter, a defensive spell based on fire fits well thematically with the succubus's fiendish nature.
5. Modify Memory: After carefully building a web of manipulation, one can't have former victims ratting you out and this is a much better option then killing a proven food source.
