The Seriousness of Breakfast
The Seriousness of Breakfast is a 4★ Light Cone for the Path of Erudition in Honkai: Star Rail.
A farmable 4-star cone for the Erudition path that grants a flat 12% DMG boost plus stacking ATK on kills, but its value is conditional on securing frequent kills, limiting its usefulness against single tough targets.
Increases the wearer's DMG by 12%. For every enemy defeated by the wearer, the wearer's ATK increases by 4%, stacking up to 3 time(s).
Though the table is set... Some people want a cup of tea first. Some people want to take a picture first. Some people want to read the newspaper first. Some people want to write a page in their notebook first. Some people want to play on their phone first. "All of you, eat while the food is hot!"
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.
