Part 1: Granblue Fantasy: Relink - Endless Ragnarok Open Beta Test Schedule

As the July 9, 2026, full release approaches, Cygames has officially pulled back the curtain on the testing phase. For those looking to get their hands on the game early, the Granblue Fantasy: Relink - Endless Ragnarok Open Beta is the most significant milestone.

Unlike the previous closed testing periods, which were limited by lottery selection, the Open Beta is designed to stress-test the new cross-platform infrastructure. This is particularly important given that Endless Ragnarok marks the franchise's debut on the Nintendo Switch 2, alongside existing versions on PlayStation 5, PlayStation 4, and Steam.

Key Dates to Remember:

• Preload Starts: April 23, 2026, at 7:00 AM UTC.
• Beta Start Time: April 24, 2026, at 7:00 AM UTC.
• Beta End Time: April 27, 2026, at 6:59 AM UTC.

During this four-day window, players can access a curated slice of the expansion. It is highly recommended to download the client as soon as preloading becomes available, as the high volume of traffic often leads to slower download speeds on day one. Since this beta serves as a network load test, being prepared ensures you maximize your time in the sky.

Part 2: Granblue Fantasy: Relink - Endless Ragnarok Open Beta Test Key Reveals

The Endless Ragnarok expansion isn't just a simple content drop; it’s a foundational shift in how Relink is played. The beta focuses on two primary pillars: introducing fan-favorite characters and showcasing the revamped combat systems.

New Playable Characters

The roster for the beta is generous, offering a mix of original crew members and highly anticipated newcomers.

• Beatrix: The star of the show. After months of anticipation, "The Blue Rose" is finally playable. Her gameplay focuses on high-risk, high-reward mechanics where her power scales as her HP fluctuates, staying true to her "Embraesque" heritage.
• Eustace: Bringing tactical long-range combat, Eustace offers a refreshing change of pace for players who prefer to control the battlefield from afar.
• Maglielle & Gallanza: Interestingly, the beta also allows players to step into the shoes of the former antagonists. Their inclusion as playable units adds a layer of "what-if" excitement to the team compositions.

Gameplay Overhauls

The most transformative addition revealed in the beta is the Summon System. For the first time in Relink, players can call upon powerful Primal Beasts to intervene directly in combat. This isn't just a cinematic ultimate; it’s a tactical tool that can be used to interrupt boss patterns or provide massive defensive buffs.

Furthermore, the beta introduces Primal Bursts. This is an evolution of the "Full Burst" mechanic from the original game. While a Full Burst occurs when all four players chain their Skybound Arts, a Primal Burst requires precise synchronization to unleash a reality-warping finishing move that deals astronomical damage. The beta includes four specific quests designed to test these mechanics, culminating in the "Sephira's Sanguine Glimmer" raid, a challenge that will push even veteran players to their limits.

To enjoy the high-octane action and vibrant art style without stuttering, your hardware needs to be up to the task. The expansion features improved lighting and particle effects that demand slightly more from your rig than the base game did.
