You craft an illusion around a creature that isn’t a Construct or Undead, creating phantom symptoms of a disease. The target must succeed on a Wisdom saving throw or suffer one or more of the following symptoms of your choice for the duration:

• An illusory fever where the target feels feverish and hot to the touch.
• The target has a persistent, scratchy throat, prompting occasional coughs.
• The target sees minor spots or has blurry vision at their periphery.
• The target’s skin manifests illusory, itchy spots, boils, or rashes, prompting occasional scratching.

Until this spell ends, the target has disadvantage on ability checks. At the end of each of the target’s turns, it can make another Wisdom saving throw. On a successful save, the spell ends. After failing three of these saving throws, the spell’s effects last for the duration.
