Dagger of Deception

5th-level necromancy

Classes: bard, warlock

Casting Time: 1 bonus action

Range: 60 feet

Components: V, S, M (a tiny sword and a set of loaded dice)

Duration: 1 minute

You create a dagger of force that glows with a sickly green radiance. The blade functions as a spiritual weapon, but in addition each time it hits the target, the target acquires a curse of unluck, causing it to have disadvantage on its next attack roll and its next saving throw. This effect cannot be dispelled but can be removed with remove curse.

At Higher Levels: When you cast this spell using a 6th level spell slot or higher, the damage increases by 1d8 for every two slot levels above the 5th.
