Ancient Curse

You pronounce an ancient and dark curse upon a creature within range that you have substantial evidence is of evil alignment. You become a conduit for this dark power, and must name the creature you intend to afflict with this curse. The named creature must make a Wisdom saving throw. On a success, they suffer no ill effects. On a failure, the creature and any living direct descendants are subjected to a curse.

This curse emulates the effects of the Bestow Curse spell with a Duration Type of "Until Dispelled". The effect is not immediate, beginning instead in 3d20 days. The curse takes effect regardless of the target's distance as long as they are on the same plane of existence as the caster.

To break the curse, a creature must receive a Ceremony spell and then succeed on a DC 20 Wisdom saving throw. 

Only the wish can restore your ability to cast this spell if lost in the way described above. 

At higher levels. When cast with a 9th-level spell slot, a successful Ancient Curse will additionally afflict any children that the target creature may have in the future.
