Black Death

A Cloud of Dark Necrotic energy streaks toward a creature(s) of your choice within range, you may choose up to 3 targets to hit with this spell. Make a ranged spell attack against each target. On a hit, the target takes 4d6 necrotic damage, and attack rolls made against the targets for the next minute have advantage, thanks to the dark cloud of Death's energy that obscures the targets vision until then.

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