Thus, erasing the spiritual intelligence of a monster is largely beneficial for ordinary Yin Yang Masters.
The advantage of erasing spiritual intelligence is that you don't have to worry about the monster rebels against his master; as long as the Yin Yang Master controls it properly, it will be at the master's whim.
However, the disadvantage also stems from this. Once the spiritual intelligence is erased, the shikigami becomes like a walking corpse, and the Yin Yang Master must constantly chant spells and give commands to engage in battle.
If control is not maintained, and the shikigami is allowed to battle autonomously, the strength they display using only the instinctual actions left after their consciousness has been erased will be only a tenth of their potential.
That the Yin Yang Master needs to devote their attention to control is one drawback. Another is that the combat prowess that the shikigami displays is linked to the control level of the Yin Yang Master.
