You grew up on the streets and now that you’re better travelled it only takes a day or so to wrap a city around your finger. You gain the following benefits: Increase your Dexterity or Charisma by 1, to a maximum of 20. You can use your streetwise instincts to gain advantage on a Dexterity (Stealth) or a Charisma (Persuasion) check after being in a city for at least 24 hours. Once you use this feature, you must finish a long rest before you can use it again. After remaining within the same city for at least 24 hours, you cannot be surprised during combat.
