Best AI Party Guide for Endless Ragnarok
Endless Ragnarok AI tier list and party builds for Conflux, Chaos solo, and Primal Burst reliability with Eugen, Cagliostro, Zeta, and Sandalphon.
Why AI Quality Matters Post-Launch
The Conflux is solo-only—your AI companions handle three of four party slots. Chaos and Fatebreaker quests also benefit enormously from AI that fires Skybound Arts on time for Primal Bursts. Ver. 2.0.2 expanded Assist Mode, but AI decision-making still varies wildly by character kit.
Launch-week community testing (GrindnStrat, Mobalytics, creator guides) converged on a clear tier list. SS-tier AI companions require minimal micromanagement and cover damage, healing, and debuffs simultaneously.
AI Tier List (Launch Week)
| Tier | Characters | Strength |
|---|---|---|
| SS | Eugen, Cagliostro, Zeta, Sandalphon | Reliable SBA timing, top DPS or support, minimal whiffing |
| S | Charlotta, Lancelot, Percival, Siegfried, Yodarha, Beatrix, Fediel, Eustace, Maglielle | Strong performers; occasional skill waste |
| A | Captain, Katalina, Narmaya, Io, Tweyen, Fraux, Gallanza | Solid but kit-dependent; Gallanza great for AFK Conflux |
| B | Rosetta, Ferry, Seofon | Usable with investment; Ferry gauge AI improved in patch |
| C | Rackam, Ghandagoza, Vane, Vaseraga | High manual ceiling; AI underperforms unless specialized |
Eustace ranks S-tier for AFK Conflux specifically—mobile ranged DPS that slides toward distant targets without player input.
Recommended SS Party Compositions
Universal solo (you + 3 AI): Eugen + Cagliostro + Zeta. Eugen provides paralysis and sniper DPS. Cagliostro heals, buffs, and revives. Zeta adds burst damage and team ATK↑. Swap Zeta for Sandalphon when you need sustained SBA chains for Primal Bursts.
Conflux Cycle 3–4 farming: Your main + Eugen + Eustace + Gallanza. Prioritizes AFK-friendly kits over burst setup. Enable Full Assist and Conflux Idling Behavior.
Chaos co-op backup: When matchmaking fails, run your DPS main with Eugen, Cagliostro, and Sandalphon. Equip Fatebreaker sigil on all mains before pushing Fatebreaker+.
Skill and Sigil Tips for AI Allies
- Eugen: Venom Grenade, Healing Bullet (utility), Sniper Vision-friendly loadout
- Cagliostro: Phantasmagoria, Reinforce, team-wide buff skills
- Zeta: Signo Drive, Arvess Fermare for paralysis synergy with Eugen
- Sandalphon: No Way Out, Ecliptic, Revan Bullet, Talvos for combo consistency
Equip team-oriented sigils on AI slots—supplementary damage and cooldown reduction benefit the whole party. Offensive sigils on your controlled character only. Use Backup Characters to borrow a developed Sandalphon or Eugen if your roster lacks investment.

Frequently Asked Questions
Can I beat Conflux with C-tier AI characters?
Yes, but expect slower clears and more deaths. SS-tier picks reduce Cycle 3–4 run time by double-digit percentages in community benchmarks.
Does AI use Summons?
AI does not manually invoke Summons. You control gauge spending. AI SBAs still contribute to Primal Burst Full Burst chains.
Is Eugen better than Sandalphon for AI DPS?
Eugen wins on consistency and debuffs. Sandalphon wins on raw burst when Primal Burst setup is the priority. Many teams run both.
