Welcome to the Cosmic City
Welcome to the Cosmic City is a 5★ Light Cone for the Path of Elation in Honkai: Star Rail.
This 5-star Elation Light Cone gives a flat SPD boost, lets Elation damage ignore 20% DEF, and directly refunds the unique "Punchline" resource when the Ultimate is used on the wearer, making it a near-irreplaceable signature pick for the self-targeting Elation Ultimate support it's built for.
Increases the wearer's SPD by 18%. The Elation DMG dealt ignores 20% of the target's DEF. When the wearer uses Ultimate on themselves, gains 20 point(s) of "Punchline." This effect can be triggered up to 1 time. And resets this trigger count after using Basic ATK 3 time(s).
Above the city, a girl's flamboyant figure bursts free from the teleporter. Endless streams of traffic, countless silhouettes of people... the bustle carries on as always. "Sure looks lively, but..." The screen before her lights up as people's joys and sorrows transform into specks of light, flowing into it. "Even the NPCs' fatigue gauges are about to max out..." "No way I'm playing a raid this boring." Following the swipe of her finger, the city lights flicker on and off. From an unnoticed corner comes a startled cry, followed by thunderous cheers echoing through the sky. "All players' Luck doubled, randomized special talents, rewards maxed out..." "Game loaded successfully! Time to run the show!" The girl leaps down as familiar notification sounds ring in her ears. Her game time has begun.
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.
