You've studied not just language, but the cultures around them, gaining the following benefits:

• The time it takes you to learn a language is halved.
• You can identify someone's general homeland and country of origin by their accent.
• If forced to make a Charisma or Wisdom check (other than Perception) as an action, you can make it as a bonus action instead.
• When you make a Charisma check to influence a creature, you can treat a roll of 9 or lower on the d20 as a 10, so long as you are speaking in their native tongue (other than Common). If you possess or obtain a class feature that already does this (such as Reliable Talent), you gain proficiency in one Intelligence, Wisdom, or Charisma skill of your choice.
