The curse of the damned

You point your finger at the creature that damaged you and it will be cursed, whenever something specific of your choice happens, the cursed person, or whoever is in charge, will take 100d12 damage. The creature can't save from this powerfll spell, and will be affected by the effect till death or the dispell of it.

At a divinity level: You can also make the curse hereditary, but the more distant the relative is from the cursed, the less powerful the magic will be, until being annulled.
