Darkbolt

You unleash four beams of jet-black night from your open palm. You can hurl them at one target or several. Make a ranged spell attack for each ray. On a hit, the target takes 2d8 necrotic damage and has disadvantage on the next attack roll it makes before the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you create one additional ray for each slot level above 5th.
