3rd ring Divine, Necromancy
You touch a creature, and that creature must succeed on a WIS save or become cursed for the duration of the spell. When you cast this spell, choose the nature of the curse from the following options:
• Choose one ability. While cursed, the target has disadvantage on ability checks and saves made with that ability.
• While cursed, the target has disadvantage on attack rolls against you.
• While cursed, the target must make a WIS save at the start of each of its turns. If it fails, it wastes its action that turn doing nothing.
• While the target is cursed, your attacks and spells deal an extra 1d8 necrotic damage to the target.
A remove curse spell ends this effect. At the GM’s discretion, you may choose an alternative curse effect, but it should be no more powerful than those described above.
