Body and Soul

Your body has reached such a feat of constitution that the body and soul become one and you gain understanding of your soul. Your body begins to change to what your soul's true form is. You gain the following benefits:

• You have advantage against death saving throws and Constitution saving throws.
• You gain resistance to necrotic damage.
• Your body and soul cannot be affected in any way unless you allow it as the two are too intertwined for others to alter in such a fashion.
