Night on the Milky Way
Night on the Milky Way is a 5★ Light Cone for the Path of Erudition in Honkai: Star Rail.
This 5-star Erudition Light Cone scales ATK with the number of enemies on the field and grants a large damage boost on Weakness Break, making it excellent for AoE break-focused casters, though its power depends on enemy count so it isn't universally best-in-slot.
For every enemy on the field, increases the wearer's ATK by 9%, up to 5 stacks. When an enemy is inflicted with Weakness Break, the DMG dealt by the wearer increases by 30% for 1 turn.
If you are concerned for the road, just look up again. When the stars look gently down, the heart would already be soaring. Every thought and every whisper, becomes a life experience that would never leave.
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.
