You touch a creature, which must succeed on a Wisdom saving throw or become cursed for the duration. Until the curse ends, the target suffers one of the following effects of your choice: - Choose one ability. The target has Disadvantage on ability checks and saving throws made with that ability. - The target has Disadvantage on attack rolls against you. - In combat, the target must succeed on a Wisdom saving throw at the start of each of its turns or be forced to take the Dodge action on that turn. - If you deal damage to the target with an attack roll or a spell, the target takes an extra 1d8 Necrotic damage.
