Curse of the coven

You call upon the powers of the dead to curse a creature within range, causing it to suffer misfortune and ill luck. The target must make a Wisdom saving throw, and on a failed save, it takes a -2 penalty to attack rolls, ability checks, and saving throws for the duration of the spell.

Additionally, if the target fails three saving throws against this spell, it is struck by a bolt of dark energy that deals 4d6 necrotic damage and knocks it prone.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the penalty to attack rolls, ability checks, and saving throws increases by 1, and the damage dealt by the bolt of dark energy increases by 1d6 for each slot level above 4th.

This spell is often used by witches to curse their enemies and bring misfortune to those who have crossed them.
