Sneak Attack

1st-Level Rogue Feature 

You know how to strike subtly and exploit a foe’s distraction. Once on your 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 weapon you use must have the Finesse property or be 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. 

The amount of your extra damage you deal increases as you gain levels in this class, as shown in the Sneak Attack column of the Rogue Progression table.
