Baleful Bolt

You hurl a ball of screaming, hateful energy toward a creature within range. Make a ranged spell attack against that creature. On a hit, the target takes 3d8 necrotic damage. Until the end of its next turn, if the creature makes an attack roll it suffers an additional 1d8 necrotic damage and must subtract 1d4 from the roll, and the effect ends.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the initial damage increases by 1d8 for each slot level above 2nd.
