You curse a creature you can see within range. The target must succeed on a Wisdom saving throw or be cursed. While cursed in this way, the target cannot lose levels of exhaustion by taking a long rest. A remove curse cast using a spell slot of eighth level or higher ends this effect.
During the casting of the spell, you can specify a condition that will cause the spell to end and release the target. The condition can be as specific or as elaborate as you choose, but the GM must agree that the condition is reasonable and has a likelihood of coming to pass. The conditions can be based on a creature's name, identity, or deity but otherwise must be based on observable actions or qualities and not based on intangibles such as level, class, or hit points.
