What about the other super important part of a sneak attack?
from the PHB:
"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."
am I missing something or it's not in the game? because right now I think the only way to reliably use a sneak attack is by standing on a hill and use a bow because of Larian's stupid height advantage.
You're looking for your target to have threatened condition as it says on the tooltip in the game. And in addition to that and standing on a hill you have true strike, guiding bolt, faerie fire, bless...
