Healing is a spirit ability which has been demonstrated largely by Lissa Dragomir. This is shown in the series as being her best skill as a spirit user. Adrian Ivashkov also displays this power, but in weaker quantities.
Lissa has demonstrated that she can heal any physical wound, although it has been discovered that this ability is rather limited in the way that it cannot be used for mental injuries.
Bringing the Dead BackEdit
It is applied that one must be very adept at healing to bring someone else back to life.
