Holiday Thermae Escapade
Holiday Thermae Escapade is a 4★ Light Cone for the Path of Nihility in Honkai: Star Rail.
A farmable 4-star cone giving a flat 16% DMG boost plus a self-applied Vulnerability debuff (+10% DMG taken) after attacking, making it a widely used pick for DoT/debuff-style characters even if it falls short of top 5-star signature cones.
Increases the wearer's DMG dealt by 16%. After the wearer attacks, there is a 100% base chance to inflict the attacked target with Vulnerability, increasing the DMG they receive by 10% for 2 turn(s). Effects of the same type cannot stack.
"Cinny, let's go try out that new special bath that recently opened." After finishing her medical duties in Okhema, the girl followed the curious child into the eclectic set of pools. "How about a Tomato Juice Massage?" Staring at the attendant's crimson-stained hands, she hugged the eager Little Ica and retreated— "I prefer something... drinkable...." "Dromas back massage, limited-time discount!" A curious dromas lowered its head, its hot breath tousling her hair. "N—Next time, maybe!" "Herbal Bath — strengthens body and soul! How many in your party?" Lured by the fragrant herbs, she tentatively dipped a foot into the pool. "This... seems healthy..." "Doot, doot-doot!" Little Ica floated blissfully on its back. "Guess even you needed a break from all we've been doing recently..." On this rare day off, sipping grape juice, the girl chatted with the red-haired child about everything from sleep tips to pastry recipes. "Oh no—Little Ica!" The child's shriek shattered the bathhouse's calm. "Doot..." "Hold on, Little Ica!"
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.
