Snow Sickness (5e Disease)
From D&D Wiki
Snow sickness is a rare airborne disease only found in cold, arctic areas, as the bacteria that cause it cannot survive anywhere else. It is thankfully not contagious. Once you are exposed to snow sickness, you must make a DC 16 Constitution saving throw or become infected. Symptoms manifest 1d10 hours after infection and include a high fever, turning a blu-ish pale, mania, compulsive hysterical laughter, and irrationality. While infected, you have disadvantage on Intelligence and Wisdom saving throws and ability checks, and Stealth checks that involve moving silently are impossible. In a stressful situation, such as combat, you must make a DC 16 Wisdom saving throw at the start of each of your turns. On a failure, you use your action to drop an item you're holding or wearing (if applicable), and then use all of your movement to move in a random direction. To determine the direction, roll a d8 and assign a direction to each die face. While affected by the disease, you will refuse to wear armor or clothing, stripping yourself naked unless you are restrained or unconscious. Most sufferers of this disease die in a matter of days from either exposure, suicidal stupidity, abandoning their friends to wander off alone in a random direction, or some combination of all three.
