Minor Rogue (5e Feat)
From D&D Wiki
Prerequisites: Dexterity 13 or higher
The streets taught you something. You gain the following benefits:
- Choose one skill you are proficient in. Your proficiency bonus is doubled for any check you make using that skill.
- Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon. You don't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll. Any effect that allows you to use the Sneak Attack feature outside of these listed circumstances works with this feature as well.
