The organism is the body's engine that sustains life. Every organism has its own natural immunity that helps it to recover from infections, viruses, or poisoning. That's why only in severe cases the body needs help to cope with these things. But in most cases, it is self-recovering.
In this magical world, there are several methods how to help the organism recover from more severe illness. It can be herbs, medicine, incantations, or spells. But many creatures still tend to count on natural immunity because although there can be hard times to cope with these things, in the end, it still gets well.
Natural immunity is a valuable ability that can help keep you safe from harm, and it also cancels all offensive blood abilities. Be sure to use it for protection in all cases.
