In this comprehensive guide, we will break down Beelzebub's lore, detail his elemental weaknesses, and provide actionable strategies to help you claim victory in the chaotic Conflux.

Who is Beelzebub? Lore and Background

Beelzebub is one of the most infamous antagonists in the Granblue Fantasy universe. In the Astral Realm, the High Council appointed him as the commander of their formidable military forces. However, his ambition far exceeded his rank. Driven by a desire to subjugate the skies and rule as the supreme king, Beelzebub committed the ultimate betrayal by murdering Lucifer, the previous Supreme Primarch.

In the endgame of Granblue Fantasy Relink, the dimensional tear known as the Conflux opens due to the residual influence of Bahamut Versa and Lilith's realm-crossing machinations. This tear allows Beelzebub to project his immeasurable power into Zega Grande. Voiced by the talented Katsuyuki Konishi, Beelzebub views mortal skydwellers as nothing more than insects to be crushed underfoot. Defeating him is crucial to closing the chaotic gates threatening the region.

Preparing for the Battle: Best Party Setup and Gear

Before jumping into the fray, your party must be meticulously prepared. Beelzebub is weak against Light-element attacks. While he possesses high elemental resistances across the board, capitalizing on his Light vulnerability will significantly speed up the fight and help you break his guard during critical DPS checks.

According to player experience and community reports, bringing characters who can inflict status ailments like Slow or Glaciate can buy your team precious seconds during his chaotic phases. Additionally, having a dedicated support or healer is highly recommended for players attempting this fight for the first time.

Character	Role	Why They Excel in This Fight
Gran / Djeeta (Captain)	Support / DPS	Provides valuable attack buffs, defense debuffs, and healing to keep the party alive.
Io	Ranged Light DPS	Capitalizes on Beelzebub's Light weakness with high-damage Stargaze spells from a safe distance.
Charlotta	Melee DPS	Offers rapid-fire Light attacks, invincibility frames, and excellent mobility to dodge AoE hazards.
Cagliostro	Support / Buffer	Revives fallen allies, heals the party, and boosts critical hit rates for the entire team.

Your sigil loadout is just as important as your character choices. Because Beelzebub hits incredibly hard, balancing offense with defense is the key to surviving his onslaught.

Sigil Name	Recommended Level	Primary Benefit
Damage Cap V	Level 15 (Maxed)	Essential for maximizing your damage output once you hit the base damage ceiling.
Guts	Level 15	Allows you to survive a lethal blow with 1 HP remaining, preventing instant wipes.
Autorevive	Level 15	Automatically revives your character after a short delay, saving valuable potion stock.
Potion Hoarder	Level 15	Increases the number of green, blue, and mega potions you can carry into the arena.
War Elemental	Max	Converts all your attacks into the enemy's elemental weakness (Light), boosting overall DPS.

Key Mechanics of the Endless Ragnarok Beelzebub Boss Fight

When entering the endless ragnarok beelzebub boss fight, players must adapt to a fast-paced environment filled with dark magic, teleportation, and arena-wide shockwaves. Beelzebub does not fight like standard bosses; he utilizes a variety of displacement abilities to keep players off-balance.

One of his signature mechanics is the "Chaos Element," which manifests as dark pools of energy scattered across the floor. Stepping into these pools inflicts debuffs and rapidly drains your health. Additionally, Beelzebub frequently teleports behind the active player, launching quick slash attacks that can easily deplete your health bar if you fail to dodge or block in time.

Attack Name	Visual Tell	How to Counter / Avoid
Black Flies	Purple glowing spheres surround Beelzebub.	Run in a circular pattern around the arena; do not stand still.
Langula	Beelzebub raises his hand and summons a dark vortex.	Keep your distance and use ranged attacks; avoid the center of the vortex.
Chaos Calamity	The screen darkens, and multiple red indicators appear.	Time your dodges carefully or hold your block button to mitigate damage.
Anthem of Doom	Beelzebub teleports to the center and charges energy.	Execute a full Link Attack or chain Skybound Arts (SBA) to interrupt the cast.

Step-by-Step Strategy to Defeat Beelzebub

To consistently clear the endless ragnarok beelzebub boss fight, your team needs to coordinate their Skybound Arts (SBA) and Link Attacks. Saving your SBA chain for his Overdrive phase is a proven strategy that prevents him from executing his most dangerous attacks.

Phase 1: The Astral Commander

At the start of the battle, Beelzebub is relatively passive but will test your positioning. He will use basic slash combos and teleport frequently. Focus on building your SBA gauge and landing Link Attacks. Do not waste your big cooldowns here; instead, focus on learning his attack patterns and keeping your health above 80%.

Phase 2: The Conflux Overdrive

Once Beelzebub enters Overdrive, his aggression increases exponentially. He will cover the arena in dark energy waves and initiate his "Chaos Calamity" ultimate attack. As soon as the Overdrive animation begins, unleash a chained SBA. This will freeze the boss in place, letting you bypass a significant portion of his dangerous Overdrive phase.

Phase 3: The Sky-Shattering Finale

When Beelzebub's health drops below 30%, he enters his final phase. The arena boundaries shrink, and he begins casting a massive, realm-ending spell. This is a strict DPS check. You must utilize all remaining offensive skills, Link Attacks, and any saved SBA gauges to break his shield before the timer runs out. Failure to do so will result in an immediate party wipe.

Phase	Boss HP Range	Primary Focus	Key Danger
Phase 1	100% - 70%	Gauge Building & Positioning	Teleportation Slashes
Phase 2	70% - 30%	SBA Chaining & Crowd Control	Chaos Calamity AoE
Phase 3	30% - 0%	Maximum DPS Burst	Enrage Timer (Wipe Mechanic)
