Description
A fathomless crystal. Ascension material for the Trailblazer.
Lore
Severed from the highest of beings, this crystal reflects ever-changing mirages. The past and future intertwine on each of its countless facets, attempting to swallow up all observers. "Civilization is but a thin sheet of ice on top of the deep dark ocean of chaos."
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.
