Child of Desirre

One of your ancestors was a succubus or incubus. Their hellish blood flows through your veins, granting you some of their innate magic and abilities. You gain the following benefits:

• Increase your Charisma score by 1, up to a maximum of 20.
• You gain proficiency in the Persuasion skill. If you're already proficient in it, your proficiency bonus is double for any check you make with it.
• You gain the ability to alter your physical features as per the Change Appearance option of the alter self spell, and may do so once per long rest. 
• You learn charm person and enthrall, each of which can be cast once without expending a spell slot. You regain the ability to cast the spell in this way when you finish a long rest. Charisma is your spellcasting ability for these spells.
