Delayed Dagger

You brandish a dagger used in the spell’s casting and make a ranged weapon attack with it against one creature within the weapon's range (20/60 feet). On a hit, the target suffers the weapon attack’s normal effects and a second, spectral dagger begins to orbit them menacingly until the start of your next turn.

If the target makes an attack or casts a spell before the start of your next turn, the spectral dagger strikes, dealing 1d8 Force damage to the target, and the spell ends.

At Higher Levels: This spell’s damage increases when you reach certain levels. At 5th level, the initial ranged weapon attack deals an extra 1d8 Force damage to the target on a hit, and the damage the target takes for making an attack or casting a spell increases to 2d8. Both damage rolls increase by 1d8 at 11th level (2d8 and 3d8) and again at 17th level (3d8 and 4d8).
