Sneak Attack

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. [finesse and ranged weapons only] You don't need advantage on the
attack roll if another enemy of the target is within
5' of it, that enemy isn't incapacitated, and you
don't have disadvantage on the attack roll.
Damage increases by 1d6 every 2 levels to a
maximum of 10d6.
