Description

Consciousness fuses with matter, giving rise to the embryo of memory. Used to level up Traces slightly for Remembrance characters.

Lore

This thing does not truly exist until you see, hear, or sense something. This existence born from sensations soon falls silent, buried in the soil of thought — it may sprout one day, or it may not. "Such is the substance that forms our bodies, existing because you remember."

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.
