The release of the Endless Ragnarok expansion for Granblue Fantasy: Relink introduces high-stakes endgame encounters where traditional damage rotations are no longer enough to secure victory. To conquer Chaos-difficulty quests like the fight against Beelzebub or The World, players must master the game's ultimate offensive mechanic: the Primal Burst. This Endless Ragnarok Primal Burst guide walks you through the exact steps required to execute this devastating attack, detailing how to sync your party's skills, manage link time, and summon powerful entities to maximize your damage output. Learning Endless Ragnarok how to trigger Primal Burst is essential for clearing the game's most brutal Fatebreaker quests and securing Weapon Transcendence materials.
Mechanics of the Primal Burst
A Primal Burst is an advanced combat maneuver that replaces the standard Full Chain Skybound Art (SBA) when specific conditions are met. In Chaos-difficulty quests and above, Lyria's Summon System becomes active. Each of the four party members can equip up to four summons, though only one can be actively fielded on the map at any given time.
To transition a standard 4-Chain SBA into a Primal Burst, the chain must be executed entirely within Link Time while an active summon is present on the battlefield. When these systems overlap, the final hit of the SBA chain is replaced by a unique, summon-specific cinematic attack that deals massive neutral or elemental damage, bypasses standard damage caps, and applies permanent debuffs to the target.
During Link Time, your party gains increased critical hit rate, faster skill cooldowns, and accelerated SBA gauge generation. The table below outlines the damage scaling and bonus modifiers applied to the final Primal Burst based on your current Link Temp level and the active chain count.
| Chain Count | Link Temp Level | Damage Multiplier | Damage Cap Break | Bonus Effect |
|---|---|---|---|---|
| 2-Chain (Dual) | 100% (Link Time) | 1.5x | +10% | Minor defense reduction (10% for 10s) |
| 3-Chain (Triple) | 100% (Link Time) | 2.2x | +25% | Moderate defense reduction (20% for 15s) |
| 4-Chain (Full) | 100% (Link Time) | 4.0x | +50% | Summon-specific Primal Burst activation |
| 4-Chain (Full) | 100% + Overdrive | 5.5x | +75% | Primal Burst + Extended boss break duration |
Successfully executing a 4-Chain during Link Time freezes the Link Time decay meter. This allows your party to maintain the buffed state for the entire duration of the SBA chain animations, effectively extending your high-DPS window by up to 18 seconds. For a foundational look at how summons operate outside of these combo chains, refer to our summon system overview.
Step-by-Step Guide to Triggering a Primal Burst
Executing this high-damage combo requires coordination, especially in multiplayer lobbies where lag and misaligned SBA gauges can ruin the chain. Follow these steps to ensure a flawless execution during high-tier hunts.

Step 1: Accumulate Link Gauge and SBA Gauges
Your first objective is to build the party's Link Gauge to 100% while simultaneously charging all four characters' SBA gauges to 100%. Use multi-hit skills, perform perfect dodges, and execute Link Attacks whenever the blue prompt appears.
Step 2: Trigger Link Time
Once the Link Gauge reaches 100%, trigger a Link Attack. This initiates Link Time, slowing down the boss and granting your party enhanced combat stats. Do not activate your SBAs immediately; wait for the summon phase.
Step 3: Field the Summon
Immediately after entering Link Time, the player designated as the summoner must call their active Primal Beast (such as Lucilius or Rolan). This is a core component of the Endless Ragnarok Skybound Arts summon combo. The summon will appear on the field and begin attacking automatically or under player control.
Step 4: Initiate the SBA Chain
The first player initiates their Skybound Art. To maximize the Link Time duration, do not rush the subsequent activations. Wait until the first character's SBA animation is roughly 80% complete (indicated by the yellow circular timer on the screen) before the second player triggers theirs. Repeat this for the third and fourth players.
Step 5: Unleash the Primal Burst
Once the fourth SBA connects, the active summon will absorb the elemental energy of the chain and unleash the Primal Burst. The boss will be locked in a hard knockdown state for 8 seconds following the attack, allowing your party to land easy follow-up damage.
Summon Roster and Burst Modifiers
The specific effects of a Primal Burst depend entirely on which summon is active on the field when the 4-Chain SBA is completed. Controllable summons like Lucilius and Rolan offer the highest raw damage multipliers, while passive summons provide utility buffs.
| Summon | Element | Active Ability | Primal Burst Modifier | Unique Burst Effect |
|---|---|---|---|---|
| Lucilius | Light | Paradise Lost | 6.0x Damage | Deals neutral damage, bypasses all elemental resistances |
| Rolan | Wind | Sanctum Barrier | 4.5x Damage | Grants party-wide Invincibility (10s) and resets cooldowns |
| Proto Bahamut | Dark | Ragnarok Flare | 5.0x Damage | Inflicts permanent Burn and 30% Defense Down |
| Tiamat Omega | Wind | Tempest Vane | 4.0x Damage | Restores 100% HP to all active party members |
| Colossus Omega | Fire | Dimensional Cleave | 4.2x Damage | Increases party's critical hit damage by 30% for 30s |
When planning your loadout, ensure at least one player has Lucilius or Rolan equipped in their primary slot. The remaining players should equip passive summons that boost SBA generation rates or increase the damage cap of the Primal Burst itself.

Character Selection and Sigil Builds for Fast Burst Setup
To consistently pull off Primal Bursts in high-difficulty content, your party composition must focus on rapid SBA generation and quick Link Gauge accumulation. Characters with fast multi-hit attacks or specialized SBA-building mechanics are highly valued in the current meta.
Top Characters for SBA Generation
- Sandalphon (SS-Tier): Utilizing his Supreme Primarch Mode allows Sandalphon to spam lightstep sword waves. This rapid attack sequence builds his SBA gauge faster than almost any other character in the game. Learn how to optimize his setup in our Sandalphon build guide.
- Cagliostro (S-Tier): Her Collapse spam and quick charge attacks allow her to trigger frequent Link Attacks, making her excellent for entering Link Time quickly.
- Lancelot (S-Tier): His high-frequency twin blade attacks and perfect dodge counters generate massive amounts of SBA gauge in short windows.
Recommended Sigil Configurations
To maximize the efficiency of your Endless Ragnarok link time summon guide strategies, players should slot specific utility sigils. The table below lists the essential sigils required to optimize your Primal Burst setup.
| Sigil Name | Tier | Max Level | Primary Effect | Strategy for Primal Burst |
|---|---|---|---|---|
| Uplift V+ | A-Tier | 15 | Increases SBA gauge gain by up to 30% | Mandatory for all four party members to sync SBA timings. |
| Nimble Onslaught V+ | A-Tier | 15 | Grants SBA gauge (+5%) and invincibility on perfect dodge | Excellent for defensive playstyles while maintaining gauge building. |
| Link Together V+ | A-Tier | 15 | Increases Link Gauge gain by up to 25% | Reduces the time needed to enter Link Time. |
| Alpha / Beta / Gamma | S-Tier | 15 | Boosts SBA damage and raises the damage cap | Essential for increasing the raw output of the Primal Burst finisher. |
By combining these sigils with characters who have high hit counts, teams can reliably trigger two to three Primal Bursts per encounter, even in short Fatebreaker quests.
Advanced Strategies for Chaos-Difficulty Bosses
Applying the Endless Ragnarok summon damage guide principles to actual boss fights requires understanding boss phase transitions and overdrive mechanics.
Countering Beelzebub's Chaos Legion
During the Beelzebub encounter, he will periodically enter an invulnerable state to cast Chaos Legion. This attack can wipe a party instantly if not interrupted.
- Save your Link Time and SBA gauges until Beelzebub's shield gauge appears.
- Trigger Link Time immediately to slow his cast bar.
- Summon Lucilius to begin dealing continuous light damage.
- Execute the 4-Chain SBA. The resulting Primal Burst will shatter his shield instantly, knocking him out of the Chaos Legion state and leaving him vulnerable to follow-up attacks.
Locking down The World
The World frequently teleports across the arena, making it difficult to land consistent damage. To counter this, trigger your Primal Burst chain right as the boss finishes a major attack animation. The time-stop effect of the SBA chain will lock The World in place, preventing it from teleporting and ensuring the entire damage package of the Primal Burst connects.

Frequently Asked Questions
Can you trigger a Primal Burst without being in Link Time?
No. A standard 4-Chain SBA executed outside of Link Time will only result in a standard Full Chain attack. Link Time must be active, and a summon must be present on the field for the Primal Burst to trigger.
Does the element of the summon change the element of the Primal Burst?
Yes. The Primal Burst will inherit the element of the active summon. For example, triggering a burst with Colossus Omega active will deal Fire-elemental damage. Lucilius is the exception, dealing neutral damage that bypasses all elemental resistances.
Do all four players need to have the same summon equipped?
No. Only one player needs to summon their Primal Beast. The other three players can have completely different summons equipped in their grids; the active summon on the field during the SBA chain determines the type of Primal Burst executed.
How does Weapon Transcendence affect Primal Burst damage?
Weapon Transcendence increases the base stats of your weapons and unlocks higher damage caps via Slot EX rewards. Since Primal Burst damage scales directly off your characters' attack stats, having transcended weapons significantly increases the overall damage of the burst.
