A coil of sickening energy streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 necrotic damage, and its hit point maximum is reduced by half the damage dealt.

If cast by a Warlock, this spell gains the same bonuses any Invocations would grant to Eldritch Blast.

The spell creates more than one coil when you reach higher levels: two coils at 5th level, three coils at 11th level, and four coils at 17th level. You can direct the coils at the same target or at different ones. Make a separate attack roll for each coil.
