Bab 48: Skin-Grafted Wraithgrip

"Lupina will be jumping in excitement if she sees this," Verina put on a bittersweet sigh. "It's not a daily occurrence to see equipment and tools crafted this way."

"Lupina isn't dead yet."

"She is still a head out of ten of what she originally was."

"Is that a serious remark or a sarcasm?"

This method of fusing traits and properties of Calamity Objects weren't something new in this world.

It wasn't confirmed whether this rumor was true or not however, since Theotech was another can of worms in itself.

But it still suggests that we were not the first duo to find out that you could combine traits of Calamity Object A with Calamity Object B if you did a specific process to them.
