A Trail of Bygone Blood
A Trail of Bygone Blood is a 4★ Light Cone for the Path of Destruction in Honkai: Star Rail.
As a 4-star Destruction Light Cone, its unconditional +12% CRIT Rate and +24% Skill/Ultimate DMG make it a powerful, easily farmable pick widely used by Skill- and Ultimate-focused DPS.
Increases the wearer's CRIT Rate by 12%. The Skill DMG and Ultimate DMG dealt by the wearer increase by 24%.
A storm broods in the distance. Tentacles extend from the Sea of Souls, as if intending to toy with that floating, fragile life. The broken limbs of the sea beast hammer giant sprays skyward, and sink into the oceanic abyss after shattering like rubble. They say that the roar of the fight lasted for ten days and nights, overwhelming even the thunder and lightning. They say that even if a man had ten thousand lives, he would not be enough to resist the Sea of Souls's erosion. Then, courage washes away the immaturity and cold pride tempered timidity — And that thin figure stumbled onto the shore. The first ray of the morning sun shines down upon the sea's waters, dyeing it like past blood.
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.
