The Unreachable Side
The Unreachable Side is a 5★ Light Cone for the Path of Destruction in Honkai: Star Rail.
A strong 5-star cone offering hefty CRIT Rate and Max HP along with a sizable DMG boost when the wearer is attacked or spends their own HP, but it's most valuable to Destruction characters built around HP consumption, keeping it path-restricted rather than universal.
Increases the wearer's CRIT Rate by 18% and increases their Max HP by 18%. When the wearer is attacked or consumes their own HP, their DMG increases by 24%. This effect is removed after the wearer uses an attack.
He would come to this place every year, bringing new swords with him each time. He had seen all the owners of the swords draw their last breath. Every time he leaves, he would sorrowfully ponder... When would his own blade be brought here by someone else?
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.
