Kathie and Aoife will be capable of killing and reviving people using this ability. They will not require any form of physical contact, but will need to be near the person and able to see him or her. They will normally aim the ability by pointing at the person. However, this gesture will not be completely necessary. The ability will then return a dead body to life, or kill a person instantly if he or she is currently alive. It cannot heal a person before he or she dies. They also cannot use it on any animals or plants, just on humans.
