You incant and point at one creature you can see within range, cursing it with a premonition of fatally bad luck. The target must succeed on a Charisma saving throw or else be cursed until the spell ends. While cursed by the spell, it suffers the following ailments:

• It takes the maximum possible damage from any traps, environmental hazards (such as a pit of lava), falls, and collisions, instead of rolling dice.
• It has disadvantage on all saving throws, ability checks, and attack rolls that it makes.
• All attacks made against it have advantage and score a critical hit on a roll of 16–20.

A creature cursed by this spell must make another Charisma saving throw at the end of each of its turns. If it successfully saves against the spell two times, the spell ends. If it fails saves three times, it stops making saving throws against the spell. In addition, if you keep your concentration on this spell for the entire possible duration, the spell ends and the target becomes affected by a new curse with different effects, lasting for 30 days.

While affected by this new long-lasting curse, the DM must roll a 1d20 for the target at each sunrise. On a 1, the target will meet with a dangerous encounter that day. The encounter must have an effective experience value equal to or greater than an encounter with a creature of a particular challenge rating. That challenge rating is equal to the target's level or challenge rating + your spellcasting ability modifier (minimum rating of 6). The encounter need not grant any actual experience.

After 30 days, the target repeats the Charisma saving throw. On a failure, the long-lasting curse remains for another 30 days and then the target repeats the saving throw again. On a success, the curse is removed.
