Warmth Shortens Cold Nights
Warmth Shortens Cold Nights is a 4★ Light Cone for the Path of Abundance in Honkai: Star Rail.
A farmable 4-star cone for the healer path that boosts Max HP and provides a small team-wide heal on Basic ATK or Skill, making it broadly useful for support characters though not as strong as top-tier 5-star signatures.
Increases the wearer's Max HP by 16%. When using Basic ATK or Skill, restores all allies' HP by an amount equal to 2% of their respective Max HP.
Lighting a light, she glanced at her friend beside her while holding a mug of warm chocolate. Watching her read the books and notes she gifted her. Watching her expressing a rare smile. In cold nights like this, even the tiniest bit of bliss can chase away the chills.
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.
