You do not need advantage on your attack roll to qualify for Sneak Attack. All other Sneak Attack rules still apply.

Infernal. You gain proficiency in Persuasion. When you make a Charisma (Persuasion) check to convince a creature to agree to a bargain, contract, or an agreement of any kind, you can treat a roll of 7 or lower on the d20 as an 8.

Hellish Curse

7th-level Rogue (Bloodknife) Feature
You infuse your blade with sinister magic to strike at body and soul. When you hit a creature with a melee attack that adds your Sneak Attack bonus, you can use Cunning Strike to reduce the bonus by 1d6 and force the target to make a Charisma saving throw against your Exploit save DC.

You wield infernal magic comparable to the most powerful servants of the Lords of Hell. Each time a creature fails its Charisma saving throw against your Hellish Curse feature it gains one level of exhaustion.
