Description

A mythical key that appears in the hands of the Meditative Scholars. Used to level up Traces slightly for Erudition characters.

Lore

It can unlock inspirations hidden deep within the conscience. To take hold of the key is to grasp at the darting embers of thought that lead to the forward path. "Eureka!"

Farm it smart

A Trace (skill tree) material. Harsh truth: traces devour materials late-game, especially levels 8–10. Do not level evenly — pour into Skill/Ultimate (your main damage) first, Basic ATK last.
