Honkai Star Rail 3.1 banners: Tribbie, Mydei, and full schedule

Honkai: Star Rail version 3.1 brings two new 5‑star characters, Tribbie and Mydei, split across the usual two‑phase banner cycle alongside reruns for Yunli and Huohuo. The update launched globally around February 25–26, 2025 (depending on your time zone), with Tribbie in phase 1 and Mydei in phase 2.

If you just want the basics: Tribbie is a Quantum Harmony support in the first half of 3.1, Mydei is an Imaginary Destruction damage dealer in the second half, and both arrive with their own 5‑star Light Cones on the Brilliant Fixation banner. Rerun‑wise, Yunli pairs with Tribbie, while Huohuo returns alongside Mydei.

Quick answers: 3.1 banner rundown

3.1 at a glance

• Version name: “Light Slips the Gate, Shadow Greets the Throne.”​

• Release timing: Maintenance on February 26, 2025 at 6:00 (UTC+8), about 5 hours of downtime.

• New 5‑stars: Tribbie (Quantum Harmony), Mydei (Imaginary Destruction).

• Rerun 5‑stars: Yunli (Physical Destruction), Huohuo (Wind Abundance).

• New 5‑star Light Cones: “If Time Were a Flower” (Harmony), “Flame of Blood, Blaze My Path” (Destruction).

Banner dates and phases (confirmed ranges)

Exact start times follow the usual “immediately after maintenance” pattern, but multiple official and major guide sites agree on the following windows:

1. Phase 1 – Tribbie & Yunli

   • Starts: February 26, 2025 (after 3.1 maintenance).

   • Ends: March 19, 2025.

2. Phase 2 – Mydei & Huohuo

   • Starts: March 19, 2025.

   • Ends: April 8, 2025.​

If HoYoverse ever adjusts banner timings after these ranges, treat any later shifts as overriding this schedule.

3.1 banner order: who’s in each phase?

Here’s the full 3.1 character and Light Cone layout using only confirmed info.

This structure is taken from the version 3.1 Special Program recap and confirmed banner pages rather than leaks.

Tribbie banner: path, element, and what’s actually confirmed

Tribbie’s banner is your first stop in 3.1 if you want a new support.

• Path and element: Tribbie is a Quantum character on the Path of Harmony.

• Role: Harmony units focus on buffing, turn manipulation, and team utility, and official descriptions present Tribbie as a support‑leaning unit within that archetype.

• Banner name: “Back to Fons et Origo” (Tribbie’s character warp).​

• Signature Light Cone: “If Time Were a Flower,” a 5‑star Harmony cone on the Brilliant Fixation banner during phase 1.

• Rerun with her: Yunli, a Physical Destruction 5‑star who acts as a front‑line single‑target and AoE damage dealer.

Official and large‑site write‑ups describe Tribbie as a Quantum Harmony attacker or buffer but stop short of fully breaking down her numbers. Any detailed multiplier sheets, internal scaling formulas, or unreleased trace descriptions floating around community leak hubs are not confirmed and are left out here on purpose.

Mydei banner: path, element, and confirmed details

Mydei takes over in phase 2 and fills the classic “hard‑hitting Imaginary bruiser” role.

• Path and element: Mydei is an Imaginary character on the Path of Destruction.

• Role: Destruction characters are designed as self‑reliant damage dealers that can handle both single and multi‑target fights, often trading some safety for more uptime and personal damage.

• Banner name: “Fiery Lionheart,” Mydei’s limited‑time warp.

• Signature Light Cone: “Flame of Blood, Blaze My Path,” a 5‑star Destruction cone on the phase‑2 Brilliant Fixation.

• Rerun with him: Huohuo, a Wind Abundance 5‑star healer who brings strong sustain, energy, and cleanse tools to many teams.

HoYoLAB posts and pull‑recommendation write‑ups generally frame Mydei as a flexible Imaginary DPS option, particularly if your roster lacks a strong unit in that element. However, those same sources also note that his value depends on how developed your existing Destruction and Imaginary cores are, so he’s not an automatic “must‑pull” for every account.

Should you pull Tribbie or Mydei first?

This is where it comes down to your box and what roles you’re missing.

Consider phase 1 (Tribbie + Yunli) if:

• You’re short on top‑tier Harmony supports and want a new Quantum Harmony option.

• You still need a strong Physical Destruction DPS like Yunli to round out a second or third Memory of Chaos team.

• You value long‑term account flexibility from support units more than a single new main DPS.

Consider phase 2 (Mydei + Huohuo) if:

• Your Imaginary roster feels weak and you want a dedicated Imaginary Destruction carry.

• You missed Huohuo on earlier banners and still need a premium Wind healer with energy and cleanse.

• You’re okay waiting until later in the patch to spend your pulls.

If you already have Bronya, Ruan Mei, and Sparkle built, but no Huohuo and a shaky Imaginary lineup, leaning toward Mydei’s phase with Huohuo makes more sense. If the opposite is true and your support bench is thin, Tribbie’s phase is the stronger pick.

What’s confirmed vs. still subject to change

Because this patch and its banners sit in a wider roadmap, it’s worth drawing a clear line between solid info and things that can still move.

Confirmed and safe to plan around

• 3.1 release date and maintenance window around February 26, 2025 (UTC+8), with about 5 hours of downtime.

• Two new 5‑star characters: Tribbie and Mydei, debuting in 3.1.

• Banner order: Phase 1 Tribbie + Yunli, Phase 2 Mydei + Huohuo.

• Paths and elements: Tribbie as Quantum Harmony, Mydei as Imaginary Destruction, Yunli as Physical Destruction, Huohuo as Wind Abundance.

• New 5‑star Light Cones and which phase they belong to: “If Time Were a Flower” (Tribbie, phase 1), “Flame of Blood, Blaze My Path” (Mydei, phase 2).

Unconfirmed or variable (intentionally not detailed)

• Exact skill multipliers, trace scaling, and eidolon values that only appear in pre‑release or datamined documents.

• Any future balance adjustments or rerun timing changes beyond the documented 3.1 cycle.

• Long‑term banner roadmaps beyond officially announced versions and live in‑game schedules.​

If you’re planning pulls months after 3.1, always double‑check in‑game notices or the latest official posts.
