[RPG] Does sneak attack work against an invisible enethe


Let's say a rogue and an ally are adjacent to an invisible enemy. The rogue would have disadvantage on the attack roll because the target is invisible, but at the same time an ally is adjacent to the target.

How does sneak attack work in this situation?

Best Answer

Sneak attack says (PHB p.96):

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. So, as described you cannot sneak attack.

However, advantage and disadvantage says (PHB p.173):

If circumstances cause a roll to have both advantage and disadvantage, you are considered to have neither of them, and you roll one d20. This is true even if multiple circumstances impose disadvantage and only one grants advantage or vice versa. In such a situation, you have neither advantage nor disadvantage.

So if the rogue had advantage to cancel the disadvantage (say, be being hidden) and had an ally adjacent the foe (since the disadvantage negates the advantage and vice versa) then they can sneak attack.
