The blessing that Alexandriana gave Elena through the use of this magic was called "Devotion of the Fallen Unholy Saint". This was one of the strongest blessings in the whole universe that could make someone a true powerful hero from absolutely nothing in a blink of an eye. Just this blessing alone was enough to be classified as a super cheat.
So matching it's fame, this blessing had many effects. One of the main one was a skill called "Rise of the Fallen" which was a valuable resurrection skill that even a supreme was capable of utilising.
Low level resurrection spells were useless on a high level powerhouse. But with this Rise of the Fallen skill, one would not need to worry about their resurrection method suddenly becoming useless with their growth.
