Human, Inherited Skill (5e Race Variant)
From D&D Wiki
Humans sometimes are born with gifts that make them more special than the average Joe. They are blessed from birth with a keen sense in a particular area. One could say they are prodigies. Others cite a bloodline which has honed its skills and passed them down without fail. They may not always be eye-catching, but these humans have skills others of their kind surely envy.
