Description

A chunk of dark matter captured from the void. Used to level up Traces moderately for Nihility characters.

Lore

No reflections can be seen on the surface of the black prism. Not only does it suck in all the light, it seems to also absorb the wielder's emotions, leaving only a faint feeling of emptiness. "..."

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.
