If you mostly play Granblue Fantasy: Relink solo, your AI teammates are much more important than you might think. A good AI party can make difficult bosses feel manageable, while a poorly built one can constantly get knocked out or contribute very little damage.
The nice thing about Relink’s AI is that some characters actually perform better than many players expect. Certain companions execute their combos almost perfectly, land skill shots with incredible accuracy, and make excellent use of buffs and debuffs without any micromanagement.
After the Endless Ragnarok update, a few characters continue to stand above the rest when controlled by AI. In this guide, we’ll go over the best AI teammates, recommended skills, equipment, and a few setup tips that can dramatically improve your party’s performance.
Granblue Fantasy Relink Endless Ragnarok Best AI Party Guide
For most content, this is currently one of the strongest AI lineups available.
| Character | Role | Why They’re Great |
|---|---|---|
| Eugen | Ranged DPS / Debuffer | Excellent accuracy, high damage, reliable status effects |
| Cagliostro | Support / Healer | Powerful buffs, healing, revives, and debuffs |
| Zeta | DPS / Buffer | Strong damage, Paralysis, and offensive team buffs |
This trio offers nearly everything you could ask for:
- Consistent ranged damage
- Powerful party buffs
- Reliable healing
- Enemy debuffs
- Paralysis
- Excellent AI decision-making
No matter which character you control, these three companions fit into almost every team composition.
Eugen Is One of the Best AI Companions
If you’ve ever watched an AI-controlled Eugen, you’ve probably noticed something interesting.
He almost never misses.
His AI handles Sniper Vision incredibly well, consistently landing shots that many players would struggle to hit manually.
That makes him one of the most reliable damage dealers in the game.
Best Weapon
Draconic Fire – Charring Breath
This weapon gives Eugen everything he needs to continuously deal strong ranged damage throughout longer fights.
Best Skills
Venom Grenade
Applies:
- Poison
- 20% Defense Down
This is one of Eugen’s best utility skills since it boosts both his own damage and the entire team’s DPS.
Armor-Piercing Round
A powerful shell barrage that deals:
- High damage
- Good Stun
- Area-of-effect damage
It’s especially effective against larger bosses.
Paralyzing Bullet
Switches Eugen into Sniper Vision before firing a precise shot that inflicts Paralysis.
The AI lands this attack surprisingly consistently.
Sumrak
One of Eugen’s strongest offensive skills.
He fires a continuous piercing beam that deals massive sustained damage while accurately targeting enemy weak points.
Why Eugen Works So Well as AI
Unlike many characters that rely on perfect combo timing, Eugen’s AI excels because it naturally maintains good positioning while making excellent use of his ranged toolkit.
He consistently contributes high damage without requiring player intervention.
Best Cagliostro AI Build
If Eugen is your primary ranged damage dealer, Cagliostro is the backbone that keeps the entire party alive.
She’s arguably the best support AI in the game.
Best Weapon
Zosimos
This weapon complements her supportive playstyle while maintaining respectable damage output.
Best Skills
Phantasmagoria
One of the strongest party-wide buffs available.
It increases:
- Attack
- Defense
- Critical Rate
All with a single skill.
Few support abilities provide this much value.
Mehen
Places a spear trap that reduces enemy Attack by 20%.
Besides dealing damage, it helps reduce incoming pressure on your entire party.
Reinforce
An area healing spell that restores HP to nearby allies.
The AI uses it consistently, making long boss fights much safer.
Rhizomata
This skill rescues allies from critical condition before they are defeated.
It’s essentially an emergency safety button that dramatically increases party survivability.
Cagliostro Is Amazing as AI
She doesn’t require complicated combo execution.
Instead, her AI focuses on maintaining buffs, healing teammates, and applying useful debuffs—all while still contributing respectable damage.
She’s one of the few characters that fits into literally every party.
Best Zeta AI Build
Zeta remains one of the strongest offensive AI companions thanks to her reliable damage output and useful support skills.
Best Weapon
Gae Bulg, Impaler of Ruin
This weapon enhances her offensive capabilities while allowing her to maintain excellent sustained DPS.
Best Skills
Infinite Wonders
A powerful multi-hit beam that can be chained several times.
It also applies Arvess Fermare, increasing the damage enemies take from Zeta’s attacks.
Wingclipper
A quick melee combo that applies Paralysis on the final strike.
Paralysis creates valuable openings for your entire team.
Signo Drive
Provides a 25% Attack buff to the entire party.
One of the strongest offensive support skills available.
Rain of Fury
Summons multiple spears from above.
Besides dealing solid damage, it reduces enemy Attack, improving overall survivability.
Why Zeta Excels as AI
Her AI handles her combo flow surprisingly well while consistently keeping offensive buffs active.
Combined with Eugen and Cagliostro, she helps create a balanced team capable of tackling nearly any encounter.
Equip Team-Oriented Skills
AI companions perform best when their abilities benefit the entire party.
Look for skills that provide:
- Attack buffs
- Defense buffs
- Healing
- Revives
- Paralysis
- Defense reduction
- Attack reduction
These effects increase not only their own effectiveness but also the damage and survivability of your entire group.
Use Both Offensive and Defensive Sigils
It’s tempting to stack nothing but damage Sigils.
However, surviving difficult endgame encounters is just as important.
A balanced setup usually performs much better.
Offensive Priorities
- Damage Cap
- Critical Hit Rate
- Supplementary Damage
- Stamina
- Tyranny
Defensive Priorities
- Potion Hoarder
- Autorevive
- Improved survivability traits
The AI already dodges surprisingly well, so adding defensive Sigils makes them even harder to defeat.
A strong AI party can completely transform the solo experience in Granblue Fantasy: Relink. While every character is capable of contributing, Eugen, Cagliostro, and Zeta remain some of the most dependable AI companions thanks to their excellent decision-making, consistent damage, and team-wide utility. They require very little micromanagement and perform their roles with impressive reliability.
If you’re unsure where to start, building around this trio is a safe and effective choice. With Eugen providing accurate ranged damage, Cagliostro keeping the team healthy and buffed, and Zeta adding strong offense and crowd control, you’ll have a balanced party that’s well-equipped for everything from story quests to the toughest endgame battles.
