Destined Doom

You curse one creature you can see within range to be vulnerable to a specific doom. The target must succeed on a Charisma saving throw or be cursed.  You can select a specific person, a type of weapon or creature, or a location. When the person, weapon, or creature attacks the target, or the target is in the location, they suffer a -4 penalty to their AC and take an additional 5 damage from each attack.

This spell lasts until broken by magic that can remove a curse.
