Description
Advanced upgrade material for Traces.
Lore
Only in the fleeting moment right before death, when all things appear frozen in time, can the eyes of mortal humans behold the falling forms of these spiritual feathers. Flying Aureus, Spiritus — its speed is the greatest out of the seven forms of the Reignbow's manifestation. "I spent a dozen days and nights to hunt it, only to discover it has always been inside my body."
Farm it smart
A BOSS material. The biggest pain: weekly bosses cap rewards per week, so this is often the BOTTLENECK that traps a character at the 70→80 ascension. Only fight the boss dropping mats for the character you are ACTUALLY building — do not spread thin.
