I haven’t done some 5e stuff in a while, so let’s go back to that with the Out of the Abyss season and an optional background feature.
OPTIONAL FEATURE: UNDERDARK ETIQUETTE
You have met the hostile races the call the Underdark home, and while you might not be everyone’s friend, you didn’t end up on their menus. If you fail a Charisma ability check against an Underdark creature, you may remake the check with disadvantage. You must accept the results of the second roll.
