Honkai: Star Rail: Fate/Stay Night Collab Rumors Point to Gilgamesh & Rin in Version 4.3

Honkai: Star Rail: Unconfirmed Fate/Stay Night Crossover Banners & Player Expectations

The initial Fate/Stay Night collaboration in 2025 proved to be a massive draw for Honkai: Star Rail, with Saber and Archer quickly becoming essential, meta-defining units. Now, a widely circulated leak indicates that the partnership is set to continue. Reports suggest that Gilgamesh and Rin could be introduced in Version 4.3, potentially sparking new strategic approaches among players. Given the high standards set by previous collaborative content and the ever-evolving gacha landscape, here’s how this rumored next phase might influence the Honkai: Star Rail experience leading into mid-2026.

Rumored Details: Upcoming Fate/Stay Night Collaboration

• Game Version: Honkai: Star Rail 4.3
• Anticipated Launch: June 2026 (Official dates are pending, subject to timezone announcements)
• Featured Characters: Gilgamesh (5★, speculated), Rin (5★, speculated)
• Event Activities: New quests and the potential return of the Holy Grail War game mode
• Availability: Expected across all servers/platforms unless HoYoverse specifies otherwise
• Current Crossover Characters: Saber (5★, accessible via standard banner) and Archer (event reward character)

Note: All information in this section is currently unconfirmed and may be adjusted before HoYoverse’s official livestream and patch notes are released.

Version 4.3 Banner Outlook: Alleged Schedule

Below is a tentative banner schedule for the rumored crossover, derived from available leaks and typical patch timelines. Players should always verify details through in-game announcements and official HoYoverse channels as the release date approaches.

Disclaimer: Precise banner commencement and conclusion times are not available. Banner periods generally consist of two phases, each lasting approximately 21 days (based on UTC+8 server resets). This schedule is not confirmed for Version 4.3 at the time of this publication.

The Significance of the Fate/Stay Night Collaboration

The initial Honkai: Star Rail and Fate/Stay Night event (Version 3.4, July 2025) left a profound impression. Saber, introduced as a 5★ DPS, was quickly celebrated for her potent single-target and area-of-effect damage capabilities. Meanwhile, Archer, provided as a free event character, proved valuable in newer content through his toughness-piercing abilities. Both characters have maintained high ratings over a year later, highlighting HoYoverse’s dedication to creating playable collaborative content with long-term relevance.

If the Version 4.3 banners follow this successful blueprint, players might anticipate:

• Gilgamesh potentially emerging as a Hunt or Destruction Path DPS, likely specializing in overwhelming damage output.
• Rin possibly taking on a Harmony/support role, offering critical rate or damage amplification buffs, especially with potential synergies with Archer.

Important: Official details regarding their Element, Path, Eidolons, or recommended Light Cones for either character have not been disclosed.

Crossover Event & Gameplay: Potential Returns

A highlight of the prior collaboration was the Holy Grail War event mode, which allowed players to engage in 1v1 duels, select special enhancements, and earn corresponding rewards. While there is speculation that this system could reappear for the Gilgamesh/Rin phase, no official announcements or gameplay trailers have been released as of the Version 4.2 launch.

Key elements from the previous crossover event included:
– Integration of Fate/Stay Night characters into both narrative and combat scenarios
– Event-exclusive currency exchangeable for unique collaborative items
– Distribution of a free 4★/5★ character (Archer)

Given the overwhelmingly positive player feedback on the event’s depth and rewards, future iterations are likely to emulate this success. However, specific reward details and the duration for a potential Version 4.3 rerun remain Unconfirmed and subject to change.

Pull Strategy: Advice for Free-to-Play and Low-Spending Players

Should You Prioritize Crossover Banners?

• For Free-to-Play (F2P) and budget-conscious players: Crossover banners historically have a lower chance of returning, making them highly desirable for their exclusivity. However, it’s crucial to assess if your account lacks essential sustain or primary damage units from standard banners. If your Star Rail Special Passes are limited and you need core meta coverage, consider skipping.
• Pity considerations: HoYoverse has not indicated whether crossover banners share pity with standard or limited event character banners. It’s advisable to have at least 90 Star Rail Special Passes per desired 5★ character to secure them, with more needed for constellations/Eidolons.
• Banner conflicts: The community has expressed concerns about the potential release of new forms of existing key units (e.g., Blade SP) within the same patch window. If you are aiming for multiple limited units, carefully manage your resources or await the official banner previews during the Version 4.3 livestream.

Team Compositions & Synergies: Initial Speculations

With only unconfirmed data available for Gilgamesh and Rin, early team planning should remain flexible:

• Gilgamesh as a Core DPS: Expected to serve as a primary damage dealer, likely benefiting most from buffers (e.g., Asta, Bronya, or potentially Rin if she fulfills a Harmony role).
• Rin as a Support: If designed as a Harmony character, she could provide Damage/CRIT buffs, though her kit details, Break Effects, and ideal Light Cone synergies are currently unknown.
• Saber/Archer Integration: These characters remain strong choices for diverse elemental coverage. Gilgamesh could further enhance mono-element teams if his Path complements Saber’s.

Pre-Patch Checklist for the Event

• Accumulate Star Rail Special Passes: Maintain a substantial reserve, especially with the possibility of multiple limited banners appearing in close succession.
• Complete Ongoing Story/Events: Previous banner collaborations often required specific story progression to access event content; finish any current tasks early.
• Prepare Materials: Farm universal player XP and relics, as the elements and Paths for Gilgamesh and Rin are yet to be announced.
• Monitor for Preload/Preview Updates: Livestreams and in-game notifications typically surface approximately two weeks before significant collaborative events.

Unconfirmed Details: Current Rumors

The following information is based solely on leaks and community discussion:

• The presence of Gilgamesh and Rin as playable characters is mentioned in a leak attributed to Full Stop Chan, which was re-shared by Reddit user UltraYZU.
• Their Path/element, ability kit design, banner order, and whether they will be free or gacha-exclusive characters are all currently unverified.
• Information regarding the collaborative event mode and event currency has not been stated.

All unconfirmed content is subject to revision or alteration by the time HoYoverse releases official patch notes or conducts livestreams.
