Description

Arrows belonged to a Stormbringer. Can be used for the Ascension of Wind characters.

Lore

Used to belong to a certain Fragmentum monster modeled after a certain kind of Voidrangers. An arrowhead can be barely seen buried in the center of the vortex. "Those who perish in the Fragmentum shall rise again where they met their demise."

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.
