On the Fall of an Aeon
On the Fall of an Aeon is a 5★ Light Cone for the Path of Destruction in Honkai: Star Rail.
The best FREE Destruction cone in the game (Herta Store): stacking ATK per enemy, works for every Destruction DPS — community consensus S-tier.
When the wearer attacks, increases their ATK by 8% in this battle. This effect can stack up to 4 time(s). After the wearer breaks an enemy's Weakness, increases DMG dealt by 12%, lasting for 2 turn(s).
It began with a flash of light. One by one, THEY fell as the threat of expiration loomed over THEM. THEY had to stop self-replicating and rushed to embrace each other, trying to offer the right to reproduce in exchange for a possibility of survival. THEY held hands in a show of unprecedented unity. ...But the Paths met an abrupt end, and THEY were headed to a true death.
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.
