Under the Blue Sky
For the Path of: DestructionUnder the Blue Sky is a 4★ Light Cone for the Path of Destruction in Honkai: Star Rail.
A 4-star cone giving flat ATK plus a CRIT Rate boost on landing a killing blow, decent for clearing trash mobs but unreliable against single bosses with no kills, keeping it as filler.
Under the Blue Sky is a Light Cone for the Destruction Path. Ranked B on the Light Cone tier list. Best paired with Misha. Needs 7 material types to reach Lv.80.

Story
Under the blue sky, fields of wheat were dancing. The young girl was carefully weaving a flower wreath, for her most beloved little sister. That was when they were still the same height. That was when they shared the same smile.

Trivia & Origins
HoYoverse's own game data has no gacha table pairing this cone with a specific character, and the internal flavor text doesn't name one either — not enough evidence to assign a signature owner, no guessing.

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.
