Dread Bolt

An orb of dark energy flies from your palm at a target you can see within range. Make a ranged spell attack roll. On a hit, the target suffers 4d6 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 2nd level spell slot or higher, the damage increases by 1d6 for every spell level above 1st.
