Description

A crystal made of countless ocean waves. Used to level up Traces significantly for Nihility characters.

Lore

It pulses like a beating heart and its gills open like an exhale, for an ocean still lives within it. "She pressed the ocean into her chest, trading it for eternal silence."

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.
