Curse of Miscreation (HB)

You touch a creature, which must succeed on a Wisdom saving throw or become cursed for the duration. You curse a creature's creations to bring misfortune to those who wield them. Choose a type of Artisan's Tools. As soon as the creature finishes the crafting process of an item using the chosen tools, work with your Storyteller to determine a curse property and bestow it upon the item, which therefore becomes a cursed magic item. The potency of the curse property must be appropriate to the item's rarity.

Components. The spell requires a body part, lock of hair, bit of nail, or the like that belongs to the creature. The component is consumed in the casting process. At the Storyteller's discretion, if the creature has wronged you greatly in the past, you may use your seething hatred towards it as the spell's sole component.
