Details surrounding a new 5-Star character for Honkai Star Rail, codenamed Summeretto, have surfaced through leaked beta information. This character, associated with the Wind element and The Remembrance path, is reportedly slated for release in version 4.5.
Summeretto's kit centers around a summoned entity called ‘Summer Songbirds,' which appears to be a core mechanic. Her Basic Attack, 'Soundwaves, Tuning the Ocean Breeze,' deals Wind damage based on her Max HP to a single enemy. The Skill, 'Midsummer Is the Musician of the Soul,' summons or heals the ‘Summer Songbirds,' granting Summeretto 'Vibes.' The Technique, 'We Form A Melody,' provides a team-wide damage boost for two turns at the start of combat after using the Technique. Summeretto's Talent, 'Cruising the Boundless Skies,' enhances the ‘Summer Songbirds' with stats based on Summeretto's Max HP and Speed, and accumulates Vibes to summon additional memosprites, potentially entering a 'Fever' state that reduces enemy Defense and debuffs Crowd Control effects. Her Ultimate, 'Leap into the Blue Ocean Rhapsody,' advances an ally's action and regenerates Energy, while also granting Summeretto a 'Special Guest' effect that generates Vibes when the affected ally attacks.
Additional passive abilities, known as Bonus Traces, are also detailed. 'Deviated Chord' can boost an ally's Attack or Critical damage based on Summeretto's Max HP and Vibes. 'Improvised Blues' grants 'Groove' stacks when Summeretto or her memosprite receive healing or shields, which can be consumed for Energy regeneration. 'Reconstructed Harmony' provides a significant Critical Rate increase to Summeretto and her summons.
Preparing Summeretto for combat will require specific Ascension and Trace materials. For Ascension, players will need approximately 15 Dream Collection Components, 15 Dream Flow Valves, and 15 Dream Making Engines, alongside 65 Charred Buds of Twilight and 308,000 Credits. For upgrading her Traces, the materials include 8 Tracks of Destiny, 12 High Hopes of the Falsely Enlightened, 18 Bija of Consciousness, 41 Dream Collection Components, 56 Dream Flow Valves, 58 Dream Making Engines, 69 Seedlings of Manas, and 139 Flowers of Alayas, totaling 3 million Credits.
Summeretto's Eidolons, unlocked by obtaining duplicate copies of the character, offer further enhancements. Eidolon 1, 'Stray Birds of Summer,' increases Max Vibes and grants additional Vibes under specific conditions. 'Heart Like Still Waters' (E2) allows the ‘Summer Songbirds' to record and deal True damage based on ally damage dealt. 'Gleanings of Lost Echoes' (E3) boosts the levels of Summeretto's Skill, Talent, and Memosprite Talent. 'Hearing the Chord Variations' (E4) grants immediate Vibes and increases the Speed of ‘Summer Songbirds' upon entering the 'Fever' state. 'Together, Toward a New Dawn' (E5) enhances the levels of Summeretto's Ultimate and Basic Attack. Finally, 'To Sign an Aria Untitled' (E6) significantly boosts ally All-Type Resistance Penetration and provides substantial Critical damage buffs to Summeretto and her summons when in the 'Fever' state.
It is important to note that all details regarding Summeretto's kit, materials, and Eidolons are based on leaked beta information and are subject to change prior to her official release in Honkai Star Rail.
