Past and Future
Past and Future is a 4★ Light Cone for the Path of Harmony in Honkai: Star Rail.
A farmable 4-star Light Cone whose skill-triggered 16% DMG buff for the next acting ally is a strong, broadly useful support effect for Harmony characters, making it a common team pick.
When the wearer uses their Skill, the next ally taking action (except the wearer) deals 16% increased DMG for 1 turn(s).
The wings of the paper kite in her hands were broken, brutally reminding her of her beloved's tragic passing. She kneeled next to the fire of war, eyes full of sorrow. "If you are the only one left to do this, then our sacrifice would..." Gunfire raged on, painting the sky red without dampening its majesty. She looked up at the sky, eyes full of fury.
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.
