Grace

A Grace is a unique power created by the Supreme Deity and possessed by the Four Archangels of the Goddess Clan, with the exception of Escanor who is a human.

Overview
The Graces are four unique powers created by the Supreme Deity whom she gave to her four strongest fighters, the Four Archangels, during the Holy War to fight against the Demon Clan and their strongest force, the Ten Commandments.

They are similar in principle to the Commandments created by the Demon King, but while the former places a curse on any victim who breaks the Commandment, a Grace gives the user a special ability that augments their magical power and raw power, to make up for the difference in numbers between the Commandments and Archangels.

If a Human tried to take in a Grace, unlike a Commandment which would turn them into a Demon, it would destroy their body and kill them, but for some reason Escanor seems to be the exception as he was somehow born with the Archangel Mael's Grace when he was born, thousands of years after Mael's death at the hands of Estarossa.

The Four Blessings
Flash「閃せん光こう Senkō」- It allows the user to move at amazing speeds to the point where it seems like teleportation. It is held by the Archangel, Ludociel.

Ocean「大たい海かい Taikai」- It allows the user to create an entire ocean from nothing that is cut off from the real world and also lets them turn their body into water to avoid attacks. It is held by the Archangel, Tarmiel.

Tornado「竜たつ巻まき Tatsumaki」- It allows the user to create powerful and deadly winds that can slice apart anything they touch but also to protect the user in a wind sphere. It is held by the Archangel, Sariel.

Sunshine「太陽サンシャイン Taiyō (Sanshain)」- It is considered to be the strongest of the four Graces as it allows the user to become stronger with the rise of the sun to the point where they can become nigh-invincible, but will weaken as the sun sets. It was previously held by the Archangel, Mael; after his death, it somehow went to Escanor at birth.

Domain of God
An alternate dimension created by the Graces that is cut off from all other worlds and there the users of the Graces have complete control over what happens there, making anyone weaker than them who is trapped there, completely at their mercy.

Estarossa was almost killed by the Sariel and Tarmiel in this world, but he managed to survive and break free by absorbing more than one Commandment, giving him power above both of them.
