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