Spiritual bodies can attach themselves to animals or even demons, and then take over their nests.
However, this possession cannot last long unless a wizard applies secret skills to solidify it, achieving a union of spirit and flesh.
It is said that after controlling a spiritual body, wizards often choose a host for it and invest resources to develop it into a true beast pet, used as mounts or battle pets.
This is really necessary.
Because spiritual bodies usually can only operate at night or in dark environments, if exposed to sunlight or strong light, they can easily dissipate into ash, a major limitation.
Becoming a service beast can solve this problem.
Moreover, a powerful beast pet can greatly compensate for a wizard's weakness in close combat.
