This disease comes from a curse and is not contagious. A creature so cursed must make a DC 14 Charisma saving throw to resist the allure of Tsathhogga. Once afflicted, the victim must succeed on a DC 16 Constitution saving throw every 24 hours or lose 1d4 points of Constitution as their insides turn to goo. Passing two consecutive saving throws halts the disease and the ability point damage heals normally at one point per long rest or can be cured magically.
