"How will history remember Cerydra a thousand years from now?" She was once asked. To some, she was the eminent "Imperator." That cold and cruel tyrant, that ambitious "Flamecrowned," that empress who burned the Old Era with blood and fire... Others argued she was merely a pitiful "pawn." This forsaken ruler was but a prisoner of ambition, destined to lose everything in that game of chess against the gods. And some said that in the depths of her heart, darker than the ocean's abyss, she was just a mortal named "Cerydra." One who mourned for fallen comrades, who hesitated and feared before her heavy fate, unable to move forward... "Heh. There is no need for history to remember me..." Swallowing the bitterness in her heart, she continued down that path of Flame-Chase paved with sacrifice. "It is our burning golden blood that shall engrave it!"
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.
