(Slinger's) Malice Shot

You temporarily imbue the sling bullet used in the spell’s casting and make a ranged attack with it from a sling against one creature within 45 feet of you. On a hit, the target suffers the weapon attack’s normal effects and then radiates a dark aura of energy until the start of your next turn. If the target makes an attack or casts a spell before then, the target takes 1d4 necrotic damage and the spell ends.

This spell’s damage increases when you reach certain levels. At 5th level, the ranged attack deals an extra 1 necrotic damage to the target on a hit, and the damage the target takes for making an attack or casting a spell increases to 2d4. Both damage rolls increase by 1d4 at 11th level (1d4 + 1 and 3d4) and again at 17th level (2d4 + 1 and 4d4).
