Description
Advanced upgrade material for Traces.
Lore
When the child of humanity drank of the crystal core, they lost the gift to sense human hearts. From then onward, their only purpose was to watch over the earth, bound to endless cycles of stars and moons. They continued to cherish life, yet could no longer perceive neighbors as living beings. "Prostrate upon the earth, longing for the touch of blue skies. Yet, once soaring high, the humble fragrance of grass is beyond all price..."
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.
