Spirit Dominion is the ability to have control over Spirits. The Necromancer displayed this ability and used it on Penny Halliwell; He was able to paralyse her, inflict debilitating pain and influence her actions. The control the Necromancer had over Spirits appeared to subtle but nonetheless powerful, as Penny was fully aware that she was being controlled, yet could not resist him.
