Mahisasuramardini

is the Noble Phantasm of Durga.
It means "slayer of the demonic deity, Mahisha". It is said that along with a light that seemed to cover the whole world, she attacked the water buffalo demonic deity, Mahisha, with her god-granted armaments, and murdered his whole army. According to the legend, Mahisha, who had lost all of his men, fought her while transforming into a lion, a human, an elephant, and even a water buffalo, but was killed by Durga in the end.
When this Noble Phantasm's True Name is unleashed, the True Names of the ten armaments granted to her by the gods are also unleashed at the same time, with the likes of the light of Shiva's trident, Vishnu's chakram and Indra's lightning all activating at once to annihilate the enemy without a shred of mercy.Fate/Grand Order - Durga/Kali Profile - Translated by Reddit user Konchew
