Endless Ragnarok Co-op and Crossplay Guide — Full Platform Support

With the release of the Endless Ragnarok expansion DLC for Granblue Fantasy: Relink on July 9, 2026, Cygames has introduced full cross-platform multiplayer integration. This comprehensive Endless Ragnarok crossplay guide outlines how players on PlayStation 5, PlayStation 4, Nintendo Switch 2, and PC (Steam) can team up seamlessly. By enabling Endless Ragnarok cross platform play, the global matchmaking pool is fully unified, allowing hunters to tackle high-end Chaos-difficulty raids, farm Transcendence materials, and defeat endgame bosses like Beelzebub and The World together.

Cooperative play is the fastest way to progress through the expansion's late-game systems. Whether you are seeking Endless Ragnarok co op tips to optimize your party's Link Time or searching for instructions on Endless Ragnarok how to play with friends across different ecosystems, this guide covers the technical setup, matchmaking rules, and tactical adjustments required for multiplayer success.

Setting Up Cross-Platform Sessions and Matchmaking

To connect with players on other platforms, you must utilize the in-game Cygames ID system rather than native console friends lists. The expansion supports Endless Ragnarok PS5 PS4 crossplay natively, but connecting a PlayStation player with a Steam or Switch 2 player requires enabling the "Cross-Platform Matchmaking" setting within the network options.

Step-by-Step Connection Guide

1. Retrieve Your Cygames ID: Open the Pause Menu, navigate to the "Network" tab, and locate your unique 9-digit Cygames ID (e.g., 123-456-789).
2. Enable Crossplay: Go to Game Settings > Network Settings and toggle "Cross-Platform Matchmaking" to Enabled. If this is disabled, you will only match with players on your specific platform.
3. Create or Join a Session:
   • Host a Session: Speak to the Quest Counter Clerk in Seedhollow or Folca. Select "Play Online," choose "Create Session," and set a Session Passcode if you wish to restrict access. Provide your friends with the 6-character Session ID generated in the top-right corner of the screen.
   • Join a Session: Select "Search for Session" at the Quest Counter, choose "Enter Session ID," and input the host's code to join their lobby immediately.

[Main Menu] ➔ [Network Settings] ➔ [Cross-Platform Matchmaking: ENABLED]
                                          ↓
[Quest Counter] ➔ [Play Online] ➔ [Create/Join Session via Session ID]

To ensure smooth connectivity across all systems, refer to the network parameters detailed below:

Note: While crossplay is fully supported across all systems, cross-progression (sharing your save file between PC and consoles) is not supported. Your characters, weapons, and quest progress remain bound to the platform where they were created.

Co-op Quest Progression and Difficulty Scaling

Multiplayer sessions in Endless Ragnarok scale dynamically based on the number of active human players in the lobby. If a session contains fewer than four players, the host can choose to fill the remaining slots with their own offline AI companions.

Progression Rules for Host and Guests

When completing quests in co-op, progression is shared under specific conditions:

• Unlocked Quests: If a guest player joins a quest that they have already unlocked in their own game, they will receive full quest completion credit, clearing it from their active quest list.
• Locked Quests: If a guest joins a quest they have not yet unlocked (for example, a Chaos-difficulty quest before completing the prerequisite Proud Quest "The Tale of Bahamut's Rage"), they will receive the drop rewards and experience points, but the quest will not show as "Completed" in their journal until they unlock it naturally.
• Fatebreaker Quests: These high-difficulty encounters yield critical materials for Weapon Transcendence. Every player in the session receives these materials upon completion, regardless of who hosted the quest.

Dynamic Enemy Scaling

Enemies in multiplayer receive scaling adjustments to their maximum HP and Stun gauges. The table below details the scaling multipliers applied when additional players join a lobby:

Because status ailment resistance builds up significantly faster in a full four-player lobby, coordinating the use of freeze (Lancelot) or slow (Cagliostro) is vital. To learn more about optimizing individual characters for these scenarios, consult our Sandalphon Build Guide or the Best Sigil Builds resource.

High-End Co-op Strategies: Summons and Link Time

The Summon System is a core mechanic for surviving Chaos-difficulty multiplayer quests. Unlike solo play, where Lyria’s summons are determined by your single-player loadout, co-op lobbies allow each of the four players to bring one designated summon, creating a shared pool of four summons per quest.

Triggering Primal Bursts

A Primal Burst is the ultimate cooperative attack in Endless Ragnarok. To execute it, all four players must chain their Skybound Arts (SBA) while Link Time is active.

[Reach 100% Link Temp Gauge] ➔ [Trigger Link Time via coordinated attacks]
                                          ↓
[Player 1 SBA] ➔ [Player 2 SBA] ➔ [Player 3 SBA] ➔ [Player 4 SBA]
                                          ↓
                 [PRIMAL BURST: Max Summon Damage & Buffs]

To maximize this mechanic, follow these steps:

1. Build the Link Temp Gauge to 100% by performing coordinated Link Attacks when prompted.
2. Once Link Time triggers, slow down your skill rotations and focus on landing heavy attacks to extend the timer.
3. The first player initiates their SBA. The remaining three players must chain their SBAs sequentially before the input timer expires.
4. Upon the completion of the 4-chain SBA during Link Time, the active Primal Summon will execute a Primal Burst, dealing massive elemental damage and granting party-wide passive buffs.

For details on the summons available in high-level multiplayer, see the table below:

Please note that summons can only be utilized in Chaos-difficulty quests and higher. For lower-tier farming runs, players must rely on standard skill rotations and character-specific mechanics. For solo-specific progression, refer to The Conflux Roguelite Mode guide, as co-op is disabled within that particular gateway.

Recommended Co-op Team Compositions

With 28 playable characters (including the 6 new DLC additions: Beatrix, Eustace, Fraux, Fediel, Gallanza, and Maglielle), constructing a balanced party is crucial for tackling endgame bosses like Ragnalia and the Seofon & Tweyen duo fights.

Below is an overview of the top co-op character synergies and their respective roles:

Synergizing Support and DPS

A highly effective team composition for clearing high-tier Fatebreaker quests consists of:

• Sandalphon (DPS): Focuses on maintaining Supreme Primarch Mode to shred the boss's HP.
• Beatrix (DPS/Utility): Uses her Delta Clock mechanic to freeze the boss during critical phases.
• Maglielle (Support): Keeps the party protected with shields, reducing the need for players to run defensive Sigils.
• Cagliostro (Buffer/Healer): Ensures the party maintains maximum damage output via Phantasmagoria and revives players instantly if they are caught by one-hit mechanics.

For detailed strategies on setting up these characters, you can read more on the official Cygames Granblue Fantasy: Relink Website.

Optimizing Sigils and Loadouts for Multiplayer Raids

In co-op play, your loadout must balance individual damage with team utility. Unlike solo play where you can rely on AI companions to run perfect support setups, multiplayer requires players to coordinate their Sigil configurations.

S-Tier and A-Tier Sigil Interactions

When building your character for co-op, pay close attention to how your Sigils interact with your teammates' buffs:

1. Damage Cap Sigils: Always ensure your Damage Cap is maximized (usually via Alpha, Beta, or Gamma Sigils). If you are running with a Cagliostro or a character carrying support buffs, you will easily hit your base damage cap, making these Sigils mandatory to avoid wasting buff efficiency.
2. Warpath+ Sigils: These character-specific S-tier Sigils provide unique modifiers that do not conflict with standard Attack buffs. Ensure your DPS characters have their respective Warpath+ Sigils equipped before entering Chaos-difficulty lobbies.
3. Provoke vs. Stealth: If you are playing a tank like Vane or Gallanza, equipping a Provoke Sigil helps keep the boss's attention, allowing glass-cannon DPS characters like Beatrix or Narmaya to attack from behind without interruption. Conversely, DPS characters should run Stealth Sigils to minimize aggro.

Frequently Asked Questions

Can I play The Conflux mode in co-op?

No. The Conflux is a solo-only roguelite mode accessed via the gateways in Seedhollow or the Tredame Sanctum. While you can use the materials earned in The Conflux to upgrade weapons for co-op play, the runs themselves must be completed alone.

How does matchmaking work if my friend is on a different platform?

To play with friends on other platforms, you must share your 6-character Session ID. Once they enter this ID at the Quest Counter, they will join your lobby regardless of whether they are playing on PS5, PS4, Switch 2, or PC. Make sure "Cross-Platform Matchmaking" is enabled in your Network Settings.

What happens if a player disconnects during a Fatebreaker quest?

If a player disconnects mid-quest, the game will instantly replace them with an AI companion configured to that character's current loadout. The quest will continue without kicking the remaining players, and the rewards will be adjusted back to the lower player-count scaling at the end of the match.

Do support buffs stack in multiplayer?

Identical buffs from the same character do not stack (for example, two Cagliostros casting Phantasmagoria will only refresh the duration, not double the stat increases). However, different buffs from different characters (such as Cagliostro's Phantasmagoria and Maglielle's offensive shields) will stack fully. Ensure your team coordinates their character choices to avoid redundant buff applications.
