Unto Tomorrow's Morrow
Unto Tomorrow's Morrow is a 4★ Light Cone for the Path of Abundance in Honkai: Star Rail.
This 4-star cone boosts healing while also raising the damage of allies above 50% HP, an easy-to-uptime effect that works broadly for Abundance characters, making it a solid staple pick rather than a top-tier signature.
Increases the wearer's Outgoing Healing by 12%. When an ally target's current HP percentage is greater than or equal to 50%, increases the DMG dealt by 12%.
"See you tomorrow, Tribios..." The girl wiped the tears on her cheeks when her mother went somewhere far, far away. She waited one tomorrow after another, till she grew up to be someone like her mother. She stands before the passage and grasps the Coreflame tight as she recalled her mother's words. "There are no blizzards, colds, or rain at that place..." "But if we can't see you tomorrow, then..." She falls towards the earth, leaving her young figure behind, like a shooting star across the sky — "Then, see you on tomorrow's morrow!"
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.
