Overall, Daoist Soldiers are essentially the private property of their commanders, and to be more extreme, they are an extension of the commanders themselves.
The only flaw is that both the commanders and the Daoist Soldiers will experience a corresponding decline in strength once they are separated from each other.
Gu Shanhai was able to carry out decapitation strikes because the three commanders he faced did not have their Daoist Soldiers with them and also because they had a small number of them. Otherwise, if anyone thought a decapitation strike could kill a commander and thus defeat the Daoist Soldiers, it was tantamount to suicide.
On the battlefield, if you want to go one-on-one with a commander who has his Daoist Soldiers with him, the commander can unleash the combined strength of all his Daoist Soldiers.
