Twilight Grail

Abilities
Twilight Grail has the ability to make contact with the principle of life, where the possessor is being forcefully told about how the life and soul is made. The possessor also takes in the mind and the concept of the dead, the living, and various other things as they use the Holy Grail which would result in the possessor being broken by the abundance of thoughts that enters their heart and soul when overusing Twilight Grail.

From its power to control the principle of life, Twilight Grail can bring the dead back to life as shown when Ragnarok use Twilight Grail to revive the long dead Evil Dragons and Masaomi Yaegaki. Twilight Grail can also revive the dead as many times as the user desire as long as the soul of the deceased remains intact as stated by Allen.

Twilight Grail was also used to collect information on the Lightning Dragon Emperor's soul and Annihilation Pump from Uma's former body.

Elaine's Twilight Grail is a sub-species where there are three grails instead of just one. It also has more outstanding aspects than all of the previous Holy Grail possessors where she can remove the weaknesses of creatures as much as possible. It can also grant other people immortality in the form of regeneration as long as their soul is intact as shown by Marius Tepes who managed to revive himself after having half of his body destroyed by Yuri Lucifiuge's Principal of Damnation. Elaine showed the ability to restore physical youth of a living being, as shown when she gave Vasco Strada a younger body with the Twilight Grail.

Side Effect
A side effect of the corrosion caused by overusing the Twilight Grail is the possessor gaining the ability to talk with the dead from the other world.
