Key of Wisdom

Trace Material
Light Cone Ascension Material

A mythical key that appears in the hands of the greatest prodigies of the cosmos. Used to level up Traces significantly for Erudition characters.

This is the proof of invitation to the halls of the Nous Temple. Finding the door of which this key opens is a far more arduous task than obtaining the key itself. Those who pass through the doors will immediately realize the impossibility of returning to this side. "The Erudition does not have answers to the universe, but it will teach you how to ask the right questions."
