Black Sheep

You’ve developed the skills necessary to find a new family. You gain the following benefits:

• Your Charisma increases with 1, but to the maximum 20.
• You can use the name of a known family, or a group of a special race.
• You have advantage on deception checks while you make check due to the feat. 
• If the check was succesfull then you will be friendly to the family member you met. Every time if you meet a new person of the family you need to throw a new deception check. If you fail a check the person will know that you tried to use your nasty trick. The person could ruin your status by telling others you aren't one of them. If the most of the relevant family members think that you're a family member then they could spread the myth and treat you as a member.
