The Birth of the Self
The Birth of the Self is a 4★ Light Cone for the Path of Erudition in Honkai: Star Rail.
A farmable 4-star cone that boosts Follow-Up ATK DMG by 24% and an extra 24% against sub-50% HP targets, making it strong for Follow-Up-focused characters though limited to that mechanic.
Increases DMG dealt by the wearer's Follow-Up ATKs by 24%. If the current HP percentage of the enemy target is below or equal to 50%, increases DMG dealt by Follow-Up ATKs by an extra 24%.
In the beginning, it had the exact same pose as the previous portrait. Looking at the face identical to hers, she was convinced that this was not her. "Impossible. How can two portraits be exactly the same?" She tweaked its joints, opened its eyes, and made its fingers softer. She looked happy when all the changes were done. "Completely different from yesterday. This is more like who I am today."
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.
