Deuskar

The Deuskar was one of The Fifth Deity's masks, the Mask of Salvation. It gave the user the power of defeating Shadowmaster. It allowed them to transform into a large, golden form, destroy antidermis, destroy every single Morhud, and control Life, Creation, Time, and Light.

History
The Deuskar was created for the purpose of defeating Shadowmaster. The Fifth Deity succeeded in beating him, but was mortally wounded as well. The Great Beings took the mask, and buried it underground, so it could not fall into the wrong hands.

Little did they know, where they hid it would be scraped off of the planet by an asteroid and become Omnis Magna
