Shadowburn
Shadowburn is a 3★ Light Cone for the Path of Remembrance in Honkai: Star Rail.
A 3-star cone that only grants one-time 1 Skill Point and 12 Energy on the first memosprite summon, a minor single-trigger effect that offers little lasting value.
When the wearer summons memosprite for the first time, recovers 1 Skill Point(s) and regenerates 12 Energy for this unit.
The delicate power distilled from time itself. It's all the seemingly insignificant moments that weave together a magnificent destiny. "People always attempt to erase unpleasant pasts. Such is the nature of memory."
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.
