Welcome to the ultimate Endless Ragnarok Beelzebub boss guide. Released on July 9, 2026, as part of the massive expansion DLC for Granblue Fantasy: Relink, the Beelzebub encounter stands as one of the most grueling end-game challenges in the action RPG. Fighting this powerful antagonist requires a deep understanding of high-tier mechanics, precise dodge timings, and optimized loadouts.

Before you can challenge Beelzebub, you must complete the Proud Quest "The Tale of Bahamut's Rage" to unlock the Epilogue. Once unlocked, Beelzebub can be fought in high-difficulty quests, culminating in the brutal Chaos difficulty tier where a single mistake can result in an immediate party wipe. If you are struggling with his mechanics, this guide will explain Endless Ragnarok how to beat Beelzebub by breaking down his phases, identifying the Endless Ragnarok Beelzebub weakness, and showcasing the Endless Ragnarok best team for boss fights.
Beelzebub Encounter Overview and Requirements
To face Beelzebub on Chaos difficulty, players must optimize their gear through Weapon Transcendence and unlock advanced Master Traits at Level 100. In Chaos difficulty, Beelzebub has no inherent elemental weakness, meaning players must rely on specific Sigil setups like War Elemental+ to bypass his defenses and maximize their damage output.
The fight takes place in a circular, floating arena. Beelzebub possesses high mobility, frequently teleporting across the battlefield and leaving lingering area-of-effect (AoE) zones that restrict your movement. Players must manage their damage output carefully to push him through his HP thresholds before the strict time limit expires.
| Parameter | Proud Difficulty | Chaos Difficulty |
|---|---|---|
| HP Pool | 185,000,000 | 420,000,000 |
| Time Limit | 15:00 | 10:00 |
| Damage Cap Level | Level 65 Recommended | Level 80+ Recommended |
| Key Rewards | Chaos Calamity Shards, Silver Centrum | Astral Plumes, Fatebreaker Sigils, Transcendence Materials |
| Unlock Condition | Complete "The Tale of Bahamut's Rage" | Complete Epilogue & 5 Fatebreaker Quests |
Endless Ragnarok Beelzebub Attack Patterns and Phases
Beelzebub's combat loop is defined by high-velocity teleportation, lingering dark energy pools, and massive screen-clearing ultimate moves. Memorizing the Endless Ragnarok Beelzebub attack patterns is mandatory, as mistiming a single dodge on Chaos difficulty will result in an immediate knock-out.
Phase 1: The Primarch's Fall (100% - 80% HP)
During this opening phase, Beelzebub tests your basic positioning and reaction times. He relies heavily on physical sword strikes and tracking projectiles.
- Black Flies: Beelzebub summons homing dark orbs that track the target player. Dodge Timing: Wait until the orbs are roughly two character-lengths away, then dodge forward-right to slip past their tracking arc. Do not run in straight lines, or the trailing orbs will hit your teammates.
- Langue de Chat: A rapid three-strike sword combo that concludes with a forward shockwave. Counter: Do not try to block the final hit; its stun value will break your guard instantly. Instead, use a dodge with invincibility frames (such as Lancelot's Shimmer or Sandalphon's lightstep) to slide through the shockwave.
- Shadow Wave: Beelzebub slams his wings into the ground, sending out a circular shockwave across the entire arena. Counter: Jump over the wave rather than dodging, as the active frames of the wave last longer than a standard dodge roll's invincibility window.
Phase 2: Overdrive & The Great Void (80% - 40% HP)
When Beelzebub enters Overdrive, he gains a defensive barrier that reduces all incoming damage by 50% unless shattered by Link Attacks or high-stun skills.
- Karma: Beelzebub teleports to the center and pulls all players toward him while summoning concentric rings of dark energy. Strategy: Run to the outer edge of the arena and spam dodge to resist the pull. Characters with high mobility, like Sandalphon, can use their movement skills to escape the pull zone.
- Anthem: A series of falling meteors targeted at each player. Strategy: Keep moving in a circle around the perimeter. Do not run into your teammates' paths. If a teammate is downed, do not attempt to revive them until this move concludes.
- Chaos Edge: Beelzebub fires multiple dark lasers in a fan pattern. These lasers leave lingering lines on the ground that explode after a 2-second delay. Avoid standing on the glowing purple lines.
Phase 3: Chaos Legion (40% - 0% HP)
This is the ultimate DPS check of the fight. Beelzebub flies to the sky and channels Chaos Legion, a wipe mechanic that will instantly fail the quest if the casting bar fills up.
- Chaos Legion: You must deplete his shield bar within 30 seconds. This is the optimal time to trigger your Summon System, calling upon Lucilius or Rolan to deal massive stagger damage.
- Megiddo: Giant fireballs rain down, creating lingering lava pools that inflict the Burn status effect. Players must navigate these pools while continuing to damage the boss.
| Attack Name | Visual Indicator | Danger Level | Optimal Counter Action |
|---|---|---|---|
| Black Flies | Purple swirling runes around Beelzebub | Medium | Dodge forward through the projectile path |
| Langue de Chat | Red warning lines on the floor | High | Perfect dodge or parry with Siegfried/Narmaya |
| Karma | Giant black hole in the center of the arena | Extreme | Run outwards, use mobility skills, or trigger Invincibility |
| Chaos Legion | Golden casting bar below Beelzebub's HP | Fatal (Wipe) | Trigger Link Time, use Summons, or execute Skybound Arts (SBA) |
Recommended Team Compositions for Chaos Difficulty
Choosing the Endless Ragnarok best team for boss fights is crucial because Beelzebub's massive HP pool and tight time limits on Chaos difficulty require a perfect balance of DPS, crowd control, and utility.
[Sandalphon (DPS)] <---> [Cagliostro (Support)] <---> [Vane (Tank)] <---> [Eustace (Ranged/CC)]
- Sandalphon remains the undisputed SS-Tier choice for this fight. His Supreme Primarch Mode allows him to spam lightstep sword waves from a safe distance, bypassing many of Beelzebub's close-range sweeps.
- Cagliostro is highly recommended for her Phantasmagoria buff, which increases Attack, Defense, and Critical Hit Rate for the entire party, alongside her quick resurrection capabilities.
- Vane provides unmatched defensive utility. His Rampart skill deploys an invincibility dome that protects the entire party during the Anthem meteor phase, allowing DPS characters to keep attacking without fear of taking damage.
- Eustace (one of the new DLC characters) excels at applying Slow and Paralyze debuffs, which can delay Beelzebub's teleportation animations and extend your DPS windows.
Alternatively, players can run Beatrix for high risk-reward DPS. Her Delta Clock mechanic allows her to deal massive damage when her HP is low, though this requires precise play to avoid getting one-shot on Chaos difficulty.
| Character | Role | Key Skill/Contribution | Why They Excel |
|---|---|---|---|
| Sandalphon | Main DPS | Supreme Primarch Mode | High DPS, safe ranged options, excellent mobility |
| Cagliostro | Support / Buffer | Phantasmagoria / Reinforce | Attack buffs, instant heals, and revive utility |
| Vane | Tank / Defender | Rampart | Invincibility dome protects the party during Anthem |
| Eustace | Ranged DPS / CC | Slow / Paralyze | Keeps Beelzebub in place during critical DPS windows |
Build Optimization: Sigils, Summons, and Weapon Transcendence
Understanding the Endless Ragnarok Beelzebub weakness is less about elemental matching and more about optimizing your build to bypass his high defense. Because Beelzebub is non-elemental, equipping the War Elemental+ Sigil is mandatory. This Sigil forces all your attacks to deal elemental superiority damage, granting a flat 20% damage boost that ignores standard damage caps.
To survive Beelzebub's hard-hitting attacks on Chaos difficulty, you must also utilize the new Summon System. Players can equip up to four summons, but only one can be active at a time. For this fight, equipping Lucilius as your primary summon is highly recommended; his passive bonuses boost your maximum HP and skill cooldown speed, while his active summon deals massive stun damage to break Beelzebub's Overdrive.
Furthermore, players should push their weapons through Weapon Transcendence to at least Level 10. This unlocks Slot II and Slot IV traits, allowing you to slot in extra Damage Cap and Stout Heart traits. You can farm the necessary materials for Weapon Transcendence by running The Conflux roguelite mode, which serves as the fastest source of high-tier enhancement materials.
| Sigil Slot | Recommended Sigil | Key Benefit |
|---|---|---|
| Slot 1 | War Elemental+ | Converts all damage to elemental weakness damage |
| Slot 2 | Damage Cap V+ (Alpha/Beta/Gamma) | Increases SBA damage and reduces cooldowns |
| Slot 3 | Stout Heart | Prevents flinching from Beelzebub's minor sweep attacks |
| Slot 4 | Autorevive / Guts | Vital safety net against one-hit knockouts |
| Slot 5 | Character-Specific Sigil+ | Boosts character-specific mechanics (e.g., Delta Clock for Beatrix) |
Step-by-Step Strategy: Endless Ragnarok How to Beat Beelzebub
To secure victory against Beelzebub, follow this structured tactical plan:
Step 1: The Opening Salvo (100% - 85% HP)
Do not use your Skybound Arts (SBA) immediately. Save them. Focus on building your Link Level by performing link attacks whenever Beelzebub is staggered. Use standard combos and keep your distance when he begins his Langue de Chat sword sweeps.
Step 2: Surviving the First Overdrive (85% HP)
As soon as Beelzebub enters Overdrive, he will cast Karma. Run to the edges of the map immediately. If you have Vane in your party, have him deploy Rampart to shield the team from the pull effect and falling meteors. If you do not have Vane, spam your dodge roll outwards to resist the vacuum pull.
Step 3: Breaking the Shield
Once the pull ends, unleash your high-stun skills. If your Link Level is at 100%, trigger Link Time now. This slows down Beelzebub and allows your team to bypass his defensive barrier rapidly. Aim for his back to deal extra backstab damage.
Step 4: The Chaos Legion Phase (40% HP)
When Beelzebub teleports to the center for Chaos Legion, immediately summon Lucilius. Have all four party members chain their SBAs. This triggers a Primal Burst, which instantly depletes Beelzebub's shield bar and knocks him into a vulnerable, downed state for 10 seconds.
Step 5: The Final Burn (20% - 0% HP)
Beelzebub will become highly aggressive, spamming Black Flies and Langue de Chat simultaneously. Do not get greedy. Stick to safe poke damage, prioritize dodging, and let your ranged characters (like Eustace or Sandalphon) finish him off from a safe distance.

Frequently Asked Questions (FAQ)
What is the best character to solo Beelzebub?
Sandalphon is currently the best character for soloing Beelzebub due to his Supreme Primarch Mode, which allows him to maintain high DPS while staying mobile enough to dodge Beelzebub's rapid teleportation attacks. His lightstep dodge provides generous invincibility frames, making it easier to survive Chaos difficulty.
How do I unlock the Beelzebub quest in Endless Ragnarok?
You must first complete the Proud difficulty quest "The Tale of Bahamut's Rage" to unlock the Epilogue. After completing the Epilogue, clear five Fatebreaker quests to unlock "Chaos's Descent" on both Proud and Chaos difficulties.
Which summon is best for the Beelzebub boss fight?
The Lucilius summon is the best choice. His active ability deals massive stagger damage, which is crucial for breaking Beelzebub's shield during the Chaos Legion phase, and his passive boosts your survivability by increasing your maximum HP.
Does Beelzebub have an elemental weakness?
No, Beelzebub does not have an inherent elemental weakness. To maximize your damage, you must equip the War Elemental+ Sigil, which converts your attacks into elemental superiority damage against him, effectively functioning as his weakness.
