Rot poisoning

Once infected, gain one level of exhaustion.

After the first long rest, symptoms worsen. The creature has trouble breathing and painful black boils form on its skin. As it progresses the boils erupt with blackened vine-like tendrils that wrap around the creatures limbs.

After a long rest the creature may make a DC 14 Constitution saving throw. If they succeed, remove one level of exhaustion. If the saving throw fails, gain a level.

If the creature’s dies in this way, the next time it is in shadow, it rises as a shambling Plague Fungus.

If the creature removes all levels of exhaustion it is cured of the disease. Spells such as Lesser Restoration or other effects that remove diseases can also cure the disease.
