Frost Pain Modified

Frost Pain Modified is an improved version of Zaryusu Shasha’s sword.

Description
After the lizardmen tribes' surrender, some lizardmen were taken for training in the fold of Nazarick, and Ainz procured Frost Pain for study. Through his experiments, he managed to duplicate the sword's attributes, creating a newer and improved weapon.

Abilities
After creating a modified version of Frost Pain, Ainz discovered that it turned out to be stronger than the original weapon with additional powerful output. A tool being an enchanted ice blade where it lets the user utilized a high-level spell three times a day— ‘Icy Burst', but without the special abilities to power it up. It can release a slash that can freeze everything within its range instantly and deal heavy damage.
