Eldrich Bolt

A flash of Eldrich energy streaks toward a creature of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 4d6 necrotic damage and 2d6 force damage. As an action on subsequent turns, you can cause the target to take 3d4 necrotic damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the necrotic damage increases by 1d6 for each slot level above 2nd.
