Deceiving Bolt

A burst of shadow crawls towards a creature of your choice within range. Make a ranged spell attack against the unfortunate target. On a hit, the target takes 4d6 necrotic damage, and the next attack roll made by this target before the end of your next turn has disadvantage, thanks to the heavy, occult shadows flickering around the target 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.
