Launching July 11, 2025 at 12:00 (server time) and running through the end of Version 3.6, HoYoverse’s first-ever collaboration fuses the universe of Fate/stay night: Unlimited Blade Works with Honkai: Star Rail in a grand crossover event titled “Sweet Dreams and the Holy Grail.”
Featured Characters
- Saber (Artoria Pendragon): A limited 5★ Wind Destruction unit available through the Excalibur Excelsior banner, complete with her signature Light Cone A Thankless Coronation. Her kit emphasizes repeat attacks and Ultimate Energy recovery for sustained DPS.
- Archer (Emiya Shirou): A 5★ Quantum Hunt character claimable entirely for free by logging in anytime through the event period (up to Level 60 with provided materials). His Light Cone The Hell Where Ideals Burn can also be earned by using at least 200 Star Rail Special Passes across any Version 3.4 Warp events.
Rewards & Mechanics
This event runs concurrently with the Phase 1 (July 2–22) and Phase 2 (July 23–Aug 12) portions of Version 3.4. F2P players may earn up to ≈92 pulls, with Welkin and Battle Pass players potentially reaching up to 124 pulls across the version – ideal resources for summoning Saber and obtaining Archer’s Light Cone.
Event Access Requirements
New players hoping to experience the Fate/stay night collaboration will need to complete the “Trailblaze Continuance – Penacony: Battle Without Ninjutsu” mission. This unlocks access to the collab questline and gameplay features. Players who haven’t reached that point can take advantage of the limited-time Early Access Mode, which temporarily grants access to the event content without progressing the main story, ensuring newcomers don’t miss out on this exclusive crossover.
