Resseki's Flawless Armament and Kiren's Perfect Guardna

The artifact Niflheim attached to his shield was a circular golden medallion with an aqua-colored crystal embedded into its center. Around its edges were ancient texts inscribed onto the medallion that gave off mystical energy.

Crrraaaack! Shiiiiing!

The next moment, the artifact opened and split into five separate pieces on the surface of Niflheim's shield. The crystal from the medallion acted as the centerpiece and the object's golden exterior which was split into four even parts, rapidly rotated around the crystal.

As it did so, numerous cracks formed throughout Niflheim's shield and created fractures of glowing light blue energy.

Woooooosh!
