Signature mechanic
Grade IV shots and perfect reload timing
Eustace fires with normal attack and reloads with unique attack, and his firepower drops the further he stands from the target — so he is a ranged character who wants to be close. Reloading immediately after a link attack or on a full Loaded gauge loads Heavy Ammo, and perfectly timed reloads after Grade IV shots grant Strength. The loop is: keep firepower at 100%, always reload, always charge the fifth bullet.
Eustace has good utility and is best used when you maximize his Stun. His gameplay requires you to fill his gauge to deliver efficient damage to the enemy. Overall, he's not difficult to use.— Game8 tier assessment
Support skills (passives)
Thunderwolf
Press normal attack to fire a bullet and unique attack to reload. Eustace's firepower decreases the farther he is from the target.
Fuel for the Fire
Eustace loads his gun with heavy ammo by reloading right after a link attack or with a full Loaded gauge. Landing normal attack shots fills the gauge.
How to unlock
Unlock Eustace by recruiting him at Sierokarte's Knickknack Shack in exchange for a regular Crewmate Card . He is available in the Knickknack Shack along with the release of Granblue Fantasy: Relink - Endless Ragnarok.
Strengths
- 1
High stun contribution
His kit is built around maximising stun, accelerating the party's break windows.
- 2
Strong utility for a gunner
Acidrage Howl gives him a parry-counter, which is unusual and very useful at range.
- 3
Clear optimisation rules
Three simple habits — full firepower, always reload, charge the fifth — cover most of his ceiling.
Weaknesses
- 1
Range penalty
Firepower decays with distance, forcing him into the danger zone that ranged characters normally avoid.
- 2
Reload discipline required
Missing perfect reloads costs Strength stacks and Heavy Ammo capacity.
- 3
Paid DLC character
Requires Endless Ragnarok.

Builds by progression stage
Zegagrande Legend — Maniac quests, first Proud attempts
DLC-only. He arrives already at endgame power levels.
Sigil priorities — Maniac
Damage cap is the only stat that scales here. Chase any DMG Cap trait you can roll, then critical hit rate, then raw attack.
- DMG Cap — on every sigil you can manage
- Critical Hit Rate — consistency beats spikes
- Stamina / Tyranny — cheap attack scaling
- Eustace's character sigil (single-trait version)
- Potion Hoarder — more healing per run
- Autorevive — a free second chance
- Improved Dodge — as a secondary trait, not a slot
- War Elemental — the moment a Curio gives you one
Skills to run: Play with Fire, Never Surrender, Flamek Thunder, Heaven Comes Down — the same core carries all the way to endgame.
Gearing priorities
- Ascension or Stinger weapons, fully upgraded before you chase anything rarer
- Unlock every sigil slot via the Mastery tree, then Fate Episodes for the last two
- Any DMG Cap trait you can find — attack stats alone stop mattering fast
- Critical Hit Rate, Stamina and Tyranny to pad raw output
- Potion Hoarder and Autorevive so runs do not end early
Weapons to use
No Terminus yet. Fully upgrade whichever of Eustace's standard weapons you can forge — the Collection Mastery passives from levelling every weapon matter more right now than which one you hold.
- Hraesvelgr, the Swift Eagle — Catastrophe, Regen, DMG Cap, Sigil Booster
- Flamek Thunder — HP, Garrison
- Stratomizer, the Cratermaker — ATK, HP, DMG Cap, Sigil Booster
- Ultima Gun — Weak Point DMG, Break Assassin
- Nebuchad — Critical Hit Rate, Critical DMG
Proud quests, Bahamut's Rage, Lucilius (Quest Zero)
Flamek Thunder while progressing. Build the habit of reloading on every opening, not just when empty.
Sigil loadout — Proud endgame
Alpha and Gamma sigils are essential for maximizing DMG Cap and Normal Attack DMG, which increases Eustace's heavy ammo damage. His character-exclusive sigils, Thunderwolf's Acuity and Warpath , increases DMG Cap, damage dealt, and heavy ammo capacity.
Critical Hit Rate, Supplementary Damage, Tyranny, War Elemental, and Stamina are all meant to directly increase your heavy ammo's damage.
Look for Quick Cooldown and Cascade to always have your skills ready. For survivability, Potion Hoarder and Autorevive serve as additional layers of defense for when you get hit by enemy attacks.

Sigil loadout — Fatebreaker
A central part of Eustace's build involves using Basic and Defense Stat-type Sigils to maximize Eustace's Master Traits that provide DMG Cap , HP , and DEF . Additionally, you get more DMG Cap from sigils introduced in Endless Ragnarok, such as Fatebreaker , Celestial Lumen , and Celestial Terra .
Including the summons, you should get Spartan and Berserker Echo to further increase Supplementary DMG . Make sure to always have War Elemental to always have a damage boost. Lastly, look for defensive stats such as Greater Aegis , Improved Dodge , and Steel Nerves .

For Eustace's Master Traits, his strongest style is Crux: Perfectionist . The style provides a lot of buffs and DMG Cap, but requires you to not get hit. It is his most skill intensive skill, and can be difficult to consistently maintain.
For the other styles, get nodes that provide bonuses based on equipped Sigils and additional DMG Cap to maximize damage. Additionally, get nodes that can make it easier to dodge or load Eustace's Loaded Gauge.
Execution
Combos & rotation
Eustace Heavy Ammo Combo (Endless Ragnarok)7 steps
- 1Paralyze the enemy with Heaven Comes Down
- 2Deal high stun with Flamek Thunder
- 3Fill up Loaded gauge with Normal and Charged Attacks
- 4Fire off heavy ammo
- 5Fire off more heavy ammo if Link attack is available
- 6Use Play with Fire
- 7Fire off heavy ammo
Eustace's main combo involves building up his Loaded gauge by successfully hitting Normal and Charged Attacks. Make sure to always take advantage of link attacks since it automatically gives you a full gauge.
Keep 100% Firepower
You will notice a 100%, 75%, and 30% indicator on the enemy you are currently locked on. This indicates Firepower and will directly affect the damage your bullets deal. It is ideal to stay within mid-range to always maintain 100% Firepower and maximize damage.
Always Reload
Reloading fills up your Loaded gauge based on how many bullets you used in your current clip. Failing to reload in between clips causes you to lose out on a lot of time filling up the meter, so make sure to always reload.
Always Charge the 5th Bullet
It is recommended to always charge up your 5th bullet since this increases your bullet to Grade 3, which deals decent damage. Though you can get more damage out of charging all of your bullets, it generally leaves you more vulnerable to enemy attacks.
Don't Move to Increase Fire Rate
While stationary, your fire rate for tapping through your Normal Attacks significantly increases. Ideally, you would only use your Strafe Shot when needed to maximize damage.
Kit
Skills
Recommended loadout — Play with Fire and Flamek Thunder
Play with Fire allows you to further burst down enemies since it automatically fills your gun with heavy ammo. For utility, Flamek Thunder deals a high amount of stun and damage.
Never Surrender mainly acts as an additional layer of defense by granting Mirror Image. Lastly, Heaven Comes Down can apply Paralysis, which can aid your team by disabling enemy movement.
| Skill | Effect | Applies |
|---|---|---|
| Acidrage Howl | Eustace readies to parry and counter. Upon countering, dodges backward, fires a follow-up shot, then loads his gun with heavy ammo. | |
| Fast Lane | A quick dodge that can be activated up to 3 times in a row. Dodging a hit with perfect timing fills the Loaded gauge. | |
| Flamek ThunderRecommended | Fires a high-powered shot at frontal foes. Hold while activating to charge and aim. Deals a high amount of stun. | |
| Forever Yours | Fires a lightning-infused bullet. On hit, emits an electrical discharge that jumps between nearby foes. | |
| Heaven Comes DownRecommended | Summons lightning to strike the target zone. Hold while casting to aim and prolong duration. On direct hit from its finisher, inflicts Paralysis. | |
| Never SurrenderRecommended | Grants Mirror Image and Supplementary DMG to Eustace. | |
| Play with FireRecommended | Loads Eustace's gun with heavy ammo. Briefly boosts the firepower of (square) attacks and ignores distance-based penalties. | |
| Slow Kill | Fires a spread of projectiles that inflicts ATK↓ to a foe on hit. Hold while activating to reduce spread, which boosts damage and debuff strength. |
Situational swaps: Acidrage Howl.In the endgame, you can also consider using Acidrage Howl instead of Never Surrender as an effective parry that leads to more overall DPS. It synergizes with the Perfectionist mastery style, since this requires you to not get hit.

Party
Recommended team — The Captain, Vane, and Cagliostro
- The Captain
Vane
Cagliostro
Eustace provides steady ranged DPS, so he thrives best when players have allies that can apply buffs and one that can tank hits. The Captain and Cagliostro both have access to several skills that can apply buffs, debuffs, and healing to aid the whole team. Vane is an excellent tank that can take enemy agro, so Eustace can comfortably deal damage.
