Violent Bolt

You hurl a bolt of necrotic energy at a creature within 90 feet of you that you can see. Make a ranged spell attack. On a hit the bolt deals 5d4 necrotic damage and the creature takes an additional point of damage from each attack made against it until the start of your next turn. When cast with a second level spell slot or higher the bolt deals an additional d4 of necrotic damage for each level beyond first. For every two levels above a first level spell slot, additional points of damage dealt increase by 5. Therefore when cast with a 3rd level spell slot, the bolt deals 7d4 necrotic damage and all attacks made against the victim of this spell deal an additional 6 damage until the start of your next turn.
