Hello, the older servitors are made to ‘match’ your own vibration and energy,
so that you don’t sense a difference later on (as in your don’t really sense your own energy and the remnants of it as you move around., what we do ‘sense’ is the energetic difference between you and the world around you. )
But the newer ones in the books aren’t designed like that.
Perhaps this information can be helpful to the question.
But it also doesn’t seem there some other elements at play than a normal process (of creating and using servitors)
