You are adept at learning social conventions, and you find it easy to fit in despite your reptilian ancestry.  You gain the following benefits:

• Your Charisma score increases by 1, up to a maximum of 20.
• You gain proficiency with the Deception skill and disguise kits.
• You can cast Disguise Self without expending a spell slot.  Charisma is your spellcasting ability for it.  After you cast this spell in this way, you can't do so again until you complete a long rest.
• You cannot roll lower than a 7 on Charisma (Deception) and disguise kit checks against any creatures that believe you are a race other than Yuan-Ti.
