Endless Ragnarok Sandalphon Guide — Supreme Primarch Mode and SS Tier Build

Sandalphon dominates the meta of the Endless Ragnarok expansion for Granblue Fantasy: Relink, securing his place as the sole occupant of the SS-tier. With the release of the DLC on July 9, 2026, players on PS5, PS4, Switch 2, and PC have discovered that his unique mechanics trivialize the game's hardest content. The core of his power lies in his ability to transition into Supreme Primarch Mode, a state that enhances his basic attacks into piercing light projectiles, and his high-speed dodge-canceling movement pattern known as the lightstep sword wave spam. This guide provides a comprehensive breakdown of the optimal Endless Ragnarok Sandalphon build, detailing the mechanics behind his transformation, his weapon transcendence progression, and the specific sigil setups required to maximize his DPS against Chaos-difficulty bosses like Beelzebub and The World.

To understand why Sandalphon stands alone at the top of the Endless Ragnarok Sandalphon tier rankings, one must analyze his frame data and skill scaling. Unlike traditional melee characters who must commit to long animation strings, Sandalphon can cancel his recovery animations at almost any frame using his Lightstep dodge. This allows him to maintain a continuous stream of damage while remaining completely invulnerable to enemy attacks. When combined with the expansion's new Weapon Transcendence system and Master Traits, Sandalphon reaches damage caps that other characters cannot match, making him the definitive choice for clearing high-depth runs in The Conflux and tackling Fatebreaker quests.

Supreme Primarch Mode: Mechanics and Activation

Supreme Primarch Mode is Sandalphon’s primary offensive mechanic. It is represented by a unique circular gauge located above his health bar. This gauge holds 100 units of Primarch Energy, which is accumulated by landing basic attacks, executing perfect dodges, and using specific offensive skills. Once the gauge is completely filled, pressing the heavy attack button triggers a transformation animation that grants Sandalphon six wings of light, alters his skill set, and converts his basic attacks into multi-hit sword waves.

During Supreme Primarch Mode, Sandalphon gains a flat 30% increase to his attack power, a 20% increase to his damage cap, and inherent stout heart (stagger resistance). The mode decays at a rate of 3.3 units per second, giving it a baseline duration of 30 seconds. However, landing lightstep attacks and utilizing specific skills can replenish the gauge mid-transformation, extending the duration indefinitely if executed correctly.

To optimize gauge generation, players should utilize a specific rotation: start with Elysian Blade to immediately secure 40 units, follow up with three basic light attacks, and execute a Lightstep dodge into a basic attack to trigger the finisher. This sequence fills the gauge to 100% in under five seconds. Once Supreme Primarch Mode is active, the goal shifts from building gauge to maintaining it. During the transformation, Elysian Blade changes into Paradise Lost, a high-damage area-of-effect attack that freezes the decay gauge for 4 seconds upon activation.

The Ultimate Lightstep Sword Wave Build

To maximize Sandalphon's damage output, players must construct a build centered around his lightstep sword wave spam. This playstyle relies on canceling the recovery frames of his light attacks with rapid dodges, allowing him to fire projectiles in rapid succession without completing his slow, high-commitment melee animations. The build requires a specific combination of S-tier expansion sigils and standard damage cap sigils.

The foundation of the build is the Warpath+ sigil, which is exclusive to the Endless Ragnarok expansion. This sigil increases Sandalphon's damage cap by 15% when his Primarch Energy gauge is above 50%, and adds an extra hit to every sword wave fired during Supreme Primarch Mode. Combined with War Elemental+, which forces all attacks to deal elemental weakness damage regardless of the target's element, Sandalphon can consistently hit the damage cap on every single projectile.

[Basic Light Attack] ──> [Dodge (Lightstep)] ──> [Cancel Animation] ──> [Basic Light Attack]
       │                                                                      │
       └─────────────────── (Repeat loop for continuous sword waves) ─────────┘

Required Sigil Setup

1. Sandalphon's Awakening+: Combines his two character-specific traits, reducing skill cooldowns by 3% per lightstep hit and increasing his defense by 20% while in Supreme Primarch Mode.
2. Warpath+ (S-Tier): Increases damage cap by 15% and adds extra hits to sword waves. Obtainable from high-depth chests in The Conflux.
3. War Elemental+ (S-Tier): Converts all damage to the enemy's elemental weakness.
4. Alpha V+ / Beta V+ / Gamma V+: These Lucy-tier sigils increase Skybound Art (SBA) damage, skill damage caps, and provide a barrier when activating SBA. A mix of 2x Alpha and 2x Gamma is recommended.
5. Critical Hit Rate V+: Paired with Damage Cap V sub-stats to ensure 100% critical hit rate.

This setup ensures that Sandalphon reaches his absolute damage ceiling. The inclusion of Quick Cooldown V paired with his Awakening sigil allows him to cycle his active skills, such as Defiance and Uriel's Judgment, with minimal downtime.

Weapon Transcendence and Master Traits Pathing

With the release of the Endless Ragnarok expansion on July 9, 2026, Cygames introduced Weapon Transcendence, allowing players to upgrade their fully enhanced weapons beyond level 150. For Sandalphon, transcending his Terminus Weapon, Ain Soph Aur, is the single largest power spike available. Transcendence unlocks two additional trait slots (Slot II and Slot IV) and provides a passive boost to his baseline damage caps.

To unlock Weapon Transcendence for Ain Soph Aur, players must first complete the Proud difficulty quest "The Tale of Bahamut's Rage" to unlock the Epilogue, and then farm materials from Fatebreaker quests and high-depth runs in The Conflux.

Ain Soph Aur (Level 150) ──> Transcendence Level 1 (Requires Fatebreaker Materials)
                                  │
                                  ├──> Unlock Slot II (Max Level 25 Trait)
                                  └──> Unlock Slot IV (Max Level 10 Trait)

Weapon Transcendence Progression Steps

1. Step 1: Collect 5x Fatebreaker Core and 20x Conflux Shard. Upgrade Ain Soph Aur at the blacksmith in Seedhollow. This unlocks Transcendence Level 1 and Slot II.
2. Step 2: Roll for a Slot II trait. The optimal roll is Dodge Distance Up (Level 25) or Cascade (Level 25). For Sandalphon, Dodge Distance Up is preferred as it increases the travel distance of his lightstep, allowing him to reposition across the arena while maintaining his sword wave spam.
3. Step 3: Upgrade the weapon to Transcendence Level 10 using materials dropped by Beelzebub in Chaos difficulty. This unlocks Slot IV.
4. Step 4: Roll for a Slot IV trait. The absolute best-in-slot trait is Damage Cap (Level 10), which stacks additively with your equipped sigils, pushing Sandalphon's damage output even further.

Alongside Weapon Transcendence, players must allocate their Master Points into Sandalphon's Master Traits. Unlocked at Level 100, these traits are divided into three paths: Insight, Essence, and Crux. Each path offers unique Rank Style upgrades that alter how Sandalphon performs in combat.

• Insight Path: Focuses on utility and cooldown reduction. Unlocking Rank Style 4 in this path reduces the cooldown of Sandalphon's dodge by 15%, which is vital for maintaining the lightstep spam.
• Essence Path: Focuses on Supreme Primarch Mode. Rank Style 4 increases the duration of the mode by 5 seconds and reduces the decay rate of the Primarch Energy gauge by 10%.
• Crux Path: Focuses on raw offensive power. Rank Style 4 increases critical hit damage by 15% and raises the damage cap of all lightstep attacks by 10%.

The optimal pathing strategy is to prioritize the Crux Path first to secure the damage cap increases, followed immediately by the Essence Path to extend the duration of Supreme Primarch Mode. The Insight Path should be completed last, as Sandalphon's baseline dodge frames are already highly forgiving.

Combat Strategy: Conflux Runs and Boss Encounters

Sandalphon's kit makes him exceptionally suited for both solo roguelite runs in The Conflux and high-difficulty boss encounters. In The Conflux, players navigate randomly generated combat and treasure rooms. Because health recovery is limited in deeper depths, Sandalphon's ability to deal high damage from mid-range while remaining mobile is invaluable.

When running The Conflux, players should select power-ups that synergize with dodge-canceling and skill cooldowns. Look for perks such as "Dodge Invincibility Extension" and "Attack Boost on Dodge." These perks allow Sandalphon to remain completely invulnerable for the entirety of his lightstep rotation, rendering him immune to the chaotic area-of-effect attacks common in deeper rooms.

[Enter Room] ──> [Cast Defiance] ──> [Elysian Blade to fill Gauge] ──> [Activate Supreme Primarch Mode] ──> [Spam Lightstep Sword Waves]

Boss Strategy: Beelzebub (Chaos Difficulty)

During the Beelzebub encounter, the boss will frequently shield himself and release homing dark energy projectiles. Sandalphon can counter this by utilizing his lightstep sword waves to circle around Beelzebub, staying out of his frontal attack cone while continuously dealing damage.

1. Phase 1 (Opening): Immediately cast Defiance to apply a defense down debuff to Beelzebub. Use Elysian Blade to build your gauge and enter Supreme Primarch Mode before Beelzebub completes his first teleport.
2. Phase 2 (Chaos Calamity): When Beelzebub channels his arena-wide shockwaves, do not run away. Instead, use Sandalphon's lightstep to dodge through the waves. A perfect dodge will instantly grant 25 Primarch Energy, keeping your Supreme Primarch Mode active.
3. Phase 3 (Overdrive): During Beelzebub's Overdrive state, his defense increases significantly. Trigger your party's Primal Burst by coordinating Skybound Arts during link time. If you have the summon Lucilius equipped via the Summon System, summon him during this window to deal massive light-element damage and extend the stagger duration.

By mastering the timing of the lightstep dodge-cancel, players can maintain a continuous offensive presence that bypasses the defensive phases of bosses like Beelzebub and Ragnalia. Sandalphon's high mobility, combined with the safety of his ranged sword waves, is the primary reason he is considered the absolute best character in the game. For players struggling with other high-tier encounters, our guide on The Conflux offers additional room-by-room strategies.

Frequently Asked Questions (FAQ)

How do I unlock Sandalphon in Endless Ragnarok?

Sandalphon is unlocked by completing the Proud-difficulty quest "The Tale of Bahamut's Rage" to unlock the Epilogue, and then exchanging a Gold Dhalia Badge at the Knickknack Shack in Seedhollow. Alternatively, he can be unlocked immediately if you purchased the Endless Ragnarok DLC character pass.

What is the exact input loop for the lightstep sword wave spam?

The input loop is: Light Attack -> Dodge -> Light Attack -> Dodge. You must input the dodge command immediately after Sandalphon releases the sword wave projectile, canceling the rest of the swing animation. This allows you to fire projectiles at twice the speed of his standard attack combo.

Which summon is best to equip on Sandalphon?

For Chaos-difficulty quests, the best summon to equip is Lucilius. When summoned during link time, Lucilius provides a party-wide 30% attack boost and deals massive light-element damage that aligns perfectly with Sandalphon's elemental affinity. Alternatively, Rolan can be used for defensive utility and healing.

Why is Sandalphon rated higher than other S-tier characters like Narmaya or Zeta?

Sandalphon is rated higher because his lightstep sword wave spam allows him to deal maximum damage from safe distances while maintaining constant invincibility frames via dodging. Characters like Narmaya and Zeta must commit to close-range combos that expose them to dangerous boss mechanics on Chaos difficulty, making Sandalphon far more consistent and safer to play.
