Bolts From the Grave

At 3rd level, you have learned to unleash bolts of necrotic energy from within your revived body. Immediately after you use your Cunning Action, you can make a ranged spell attack against a creature within 30 feet of you, provided you haven’t used your Sneak Attack this turn. You are proficient with it, and you add your Dexterity modifier to its attack and damage rolls. A creature hit by this attack takes necrotic damage equal to your Sneak Attack. This uses your Sneak Attack for the turn.
