Their dance glides gracefully, shadows and light silently exchanging places. She takes the other person's hand, her smile beaming into those indifferent eyes. "Beautiful Ranger... Welcome to the stage of the Remembrance. At this proximity... you are far more enchanting than one might perceive." The surroundings darken, a beam of light cascading from the dome above, tracing their evolving steps. "However, some were meant to dance with us but have yet to arrive..." In a spinning moment, she draws closer to that expressionless face, grips that cold hand, and softly inquires— "Tell me. What have you done?" As their dance steps grow hurried more and more, fragmented snippets of the past rush into her mind through their joined fingertips. In a past that stretches back further and further, she hears the sound of rain and the lamentations just before life's extinguish. Then, she sees her dance partner holding a blood-red paper umbrella in the drizzling rain. Finally, as far as her eyes can see— A field of drowned corpses bobbing in the deluge. Panic-stricken, she tries to withdraw her hand, falling backward. The surroundings brighten again, the banquet's clamor resurfacing. Her dance partner gently supports her waist, as if oblivious to the ordeal that just unfolded. "What a lovely dance that was, Memokeeper. Shall we have another go?"
How to read this Light Cone page
Every Light Cone has exactly one passive effect tied to the wielder's combat performance; that effect scales up as you Superimpose it from S1 to S5 — use the S1-S5 buttons above to see the exact numbers at each level instead of guessing or interpolating. A Light Cone only delivers its full value on a character who shares its Path; "Characters who use this cone" lists every character on that Path, while "Best users" is a narrower list pulled from real build consensus, not a guess.
Base stats (HP/ATK/DEF) are shown at Lv80 for every cone of the same rarity so they can be compared directly; a 5-star cone will always edge out 4-star and 3-star ones here — the real difference lives in the passive effect, not the flat stats. The "Alternative cones on the same Path" section suggests a few other options if you do not own the signature cone yet, or want to compare before spending ascension materials.
