Proto Bahamut Boss Mechanics & Phase Breakdown
Proto Bahamut is a multi-phase boss fight that takes place entirely on the deck of the Grandcypher. The fight alternates between ranged artillery phases and close-quarters combat. Understanding the visual cues for each phase is vital for survival, especially when aiming for the Endless Ragnarok epilogue unlock.
Phase 1: Deck Defense and Ether Cannons (100% - 80% HP)
Proto Bahamut begins the fight flying alongside the Grandcypher. During this phase, he is immune to direct melee attacks.
- Ether Cannons: Two players must man the turrets located at the port and starboard sides of the ship. Use the rapid-fire mode to shoot down the incoming elemental orbs (Red, Blue, Yellow, Green) before they impact the deck.
- Binding Crystals: Proto Bahamut will summon dark crystals that bind the Ether Cannons. Melee characters must destroy these crystals immediately to free the turrets.
- Charged Shot: When Proto Bahamut charges his breath attack, the turret players must use the heavy charged shot to strike his glowing chest core. This staggers the boss and pulls him down to the deck, exposing him to melee DPS.
Phase 2: Overdrive and Ruinous Disaster (80% - 50% HP)
Once Proto Bahamut hits 80% HP, he enters Overdrive. He will slam his claws onto the deck, initiating direct combat.
- Ruinous Disaster: The boss sweeps the deck with a beam of elemental energy. You must jump over the sweeping beam or use invincibility skills like Vane's Rampart to survive.
- Claw Slams: Avoid standing directly under his claws when they glow red. These slams deal massive physical damage and apply the Slow debuff.
Phase 3: Supernova and Elemental Crystals (50% - 15% HP)
At 50% HP, Proto Bahamut flies away and casts Supernova, a three-stage arena-wide attack.
- Stage 1 (The Pull): A black hole forms in the center of the deck. Run to the outer edges of the ship to avoid being pulled in.
- Stage 2 (Expanding Rings): Three expanding energy rings will ripple across the deck. Time your jumps to hop over each ring.
- Stage 3 (Shockwaves): Large meteorites impact the deck, creating shockwaves. Block the initial impact if you cannot time the dodge.
- Elemental Shields: Proto Bahamut returns to the deck protected by four elemental crystals (Fire, Water, Earth, Wind). The party must split up and destroy all four crystals within 30 seconds. If any crystal remains, the boss will execute an unavoidable party-wide wipe.
Phase 4: The Genesis Nova DPS Check (15% - 0% HP)
This is the most critical phase of the fight. At 15% HP, Proto Bahamut teleports to the background and begins channeling Genesis Nova. A blue casting bar will appear on the screen. If the bar fills completely (approximately 40 seconds), the party instantly wipes, resetting the quest. You must save your Skybound Arts (SBA) and Link Time specifically for this phase to stall the timer and deplete his remaining health.
| Attack Name | Phase | Danger Level | Counterstrategy |
|---|---|---|---|
| Skyfall | Phase 1 & 2 | Medium | Run to the corners of the deck; block the final meteorite impact. |
| Ruinous Disaster | Phase 2 | High | Jump over the sweeping elemental beam or use dodge-roll invincibility frames. |
| Supernova | Phase 3 | Very High | Run outwards during the pull, then jump over the three expanding rings. |
| Genesis Nova | Phase 4 | Instant Wipe | Chain four SBAs sequentially to stall the cast, then activate Link Time. |
Optimal Party Composition and Build Preparation
To clear this quest and proceed with the Endless Ragnarok how to unlock process, your party requires high damage output and utility. You must hit your character's Damage Cap to pass the 15% Genesis Nova DPS check.
Recommended Characters
- Sandalphon (SS-Tier): His Supreme Primarch Mode provides unmatched DPS and lightstep sword wave spam, making him the premier choice for clearing the elemental crystals quickly. For detailed build setups, visit our Sandalphon Build Guide.
- Vane (A-Tier): His Rampart skill creates a bubble of total invincibility. This allows the party to ignore Proto Bahamut's breath attacks and continue dealing damage during high-risk phases.
- Cagliostro (S-Tier): Provides critical offensive buffs via Phantasmagoria and offers clutch healing/revival support.
- Lancelot (S-Tier): Excellent for maintaining high damage uptime. His Kaltzwinger skill can inflict Glaciate, freezing the boss and extending DPS windows.
Sigil Loadout
Before entering the fight, ensure your characters are equipped with high-level Sigils. You can farm these using the strategies outlined in our Sigil Progression Guide.
| Sigil Name | Recommended Level | Primary Benefit |
|---|---|---|
| Damage Cap V | Level 15 (x4) | Increases the maximum damage ceiling for all skills and normal attacks. |
| War Elemental | Level 15 (x1) | Converts all attacks into the enemy's elemental weakness, boosting overall damage by 20%. |
| Potion Hoarder | Level 15 (x1) | Increases your potion inventory, giving you more green, blue, and mega potions. |
| Link Together | Level 15 (x2) | Increases Link gauge gain rate, ensuring you reach 100% Link Time by Phase 4. |
| Guts / Autorevive | Level 15 (x1) | Prevents instant defeat from missed dodges during the Supernova phase. |
Step-by-Step Strategy Walkthrough
Executing the fight correctly requires coordination, especially if you are playing with AI companions. Follow these step-by-step instructions to clear this Endless Ragnarok prerequisite quest successfully.
Step 1: Manage the Ether Cannons
At the start of the match, immediately run to the Ether Cannons. Assign two players (or let the AI handle one) to target the flying elemental orbs. Use the primary fire to pop the orbs. When Proto Bahamut prepares his sweeping breath, charge your heavy shot and fire it directly at his chest core to knock him onto the deck.
Step 2: Destroy the Binding Crystals
When the boss falls onto the deck, he will be vulnerable for approximately 15 seconds. Unleash your highest-damage skill rotations. If dark crystals spawn near the Ether Cannons, melee characters must prioritize destroying them immediately so the turret players can resume shooting down projectiles.
Step 3: Survive Supernova and Clear the Four Crystals
When Proto Bahamut's health drops to 50%, he will cast Supernova. Do not attempt to attack him. Run to the outer edge of the deck to resist the gravitational pull. Jump over the three expanding gold rings. Once the rings dissipate, four elemental crystals will spawn on the deck. Split your party: two players take the left crystals, and two take the right crystals. Destroy them all before the gauge fills.
Step 4: Execute the Final SBA Chain
When Proto Bahamut reaches 15% HP, he will retreat to cast Genesis Nova. This is where your SBA management is put to the test.
- Wait for his shield to drop (indicated by the blue bar appearing).
- Trigger your first character's SBA.
- Wait for the SBA animation to almost finish before triggering the second character's SBA. This is called "SBA chaining" and it maximizes the time the boss's casting bar is frozen.
- Complete the Full Burst (all 4 SBAs).
- Once the Full Burst finishes, your Link Gauge should be at 100%. Press the Link attack prompt to trigger Link Time.
- Spam your fastest skills to deplete his remaining HP before Link Time ends.
| Fight Phase | Boss HP | Primary Objective | Key Threat |
|---|---|---|---|
| Phase 1 | 100% - 80% | Shoot down elemental orbs; knock boss down. | Binding Crystals locking turrets. |
| Phase 2 | 80% - 50% | DPS the claws; dodge deck sweeps. | Ruinous Disaster sweep. |
| Phase 3 | 50% - 15% | Survive Supernova; destroy the 4 crystals. | Supernova gravitational pull. |
| Phase 4 | 15% - 0% | Chain SBAs; activate Link Time to finish the boss. | Genesis Nova instant wipe. |

Frequently Asked Questions (FAQ)
Can I clear this quest with AI companions?
Yes. The AI companions in Granblue Fantasy: Relink are highly competent at dodging area-of-effect attacks like Supernova. However, you must go into the game options and set their SBA usage to "Hold". This prevents the AI from wasting their Skybound Arts before the critical 15% Genesis Nova phase.
What is the drop rate for Terminus Weapons in this quest?
The base drop rate for a Terminus Weapon is approximately 5% to 8% per clear. The weapon dropped is randomized from the pool of 28 characters. You may need to run this quest multiple times to obtain the Terminus Weapon for your specific main character.
Do I need to clear this quest to unlock the new DLC characters like Beatrix and Fediel?
Yes. Completing "The Tale of Bahamut's Rage" is the mandatory prerequisite to unlock the Epilogue. The Crewmate Cards required to recruit the 6 new DLC characters are only obtainable from the quests that unlock after completing this Epilogue.
What is the best weapon to use for this fight?
You should use either a fully upgraded Ascension Weapon (Level 150) or a Stinger Weapon (Level 150) with maxed-out Weapon Masteries. This ensures you have the raw attack power needed to bypass the Genesis Nova DPS check at the end of the fight.
