Mad Monkey Fever

Mad Monkey Fever is one of the many perils to be found in the jungles of Chult.
This magical disease is caused by a light blue mist which wafts around its victims. Its effects result in temporary madness which can manifest as hallucinations, irrational fear, and other similar behaviors.
It can be cured by consuming the mashed roots of the ataaj plant or with Lesser Restoration.
