The negative effect

When negative potential energy sends negative energy from a person encased in a powerful negative power component, the effect on the targeted person can be a powerful impact of contorting, snubbing, suppressing, despoiling and draining of energy.

The person would feel the impact, but then, in the actual world, a person living in a feudal language world has many other forces impacting him, continually. If the targeted person does not have any other positive impacting force, then he or she may feel the full brunt of the impact.
