Fires a blast of lighting-like energy which extracts Souls
Soul Blasting is the ability to fire a blast of lightning-like energy that can extract the Souls of other beings. When victims are hit with a blast, the bodies fall to the ground and the soul is seperated from the body.
This power can potentially kill victims if their souls are not restored in time, thus causing the souls to move on to their respective afterlifes. The extraction and restoration of the soul to the body is mentioned to be a painful or at least an unpleasant experience.
The only known beings who possess this power are Soul Blaster Demons. One of these demons used this power on Phoebe and Paige, incapacitating them until Leo was able to restore them. ("Sword and the City")
