Eternal Splendor Weapons for Seofon, Tweyen, and Sandalphon

How to craft Seofon, Tweyen, and Sandalphon Stinger and Terminus weapons with Chaos Refinium and Mythic Artifacts in Endless Ragnarok.

Legacy Character Weapon Expansion

Ver. 2.0.2 adds new weapon tiers for three fan-favorite Arcarum characters: Seofon, Tweyen, and Sandalphon. Each receives a Stinger-tier weapon from Conflux Cycle 2 materials and a Terminus-tier Eternal Splendor variant from Cycle 4. Cygames also simplified recruitment—two normal Crewmate Cards now unlock each character instead of requiring special cards.

These weapons integrate with the new Transcendence system and compete with existing Ascension gear for endgame DPS. Prioritize mains who anchor your Chaos and Fatebreaker teams.

Replay main story chapters via Chapter Select to farm additional Crewmate Cards from Chapter 5–9 treasure if you still need recruitment tokens. Cards drop from Avia's Trap, Relics in the Sand, Another Round of Duels, and Tainted Wind.

Material Farming Route

  1. Unlock Conflux Cycle 2 by clearing Hard-difficulty expansion quests
  2. Farm Chaos Refinium from Cycle 2 surveys—use AFK farming for overnight runs
  3. Craft Stinger weapons at the blacksmith; equip before pushing Maniac content
  4. Progress Endless Ragnarok story to unlock Conflux Cycle 4
  5. Farm Mythic Artifacts from Cycle 4 for Eternal Splendor Terminus forging
  6. Apply Transcendence after standard max upgrades for additional stat ceilings

Ultimate Memory from The Final Report and The Tale of Bahamut's Rage still applies to base roster Terminus forging—do not confuse those materials with Arcarum Stinger requirements.

Build Impact at Launch

Sandalphon remains a top DPS pick; Eternal Splendor Efes pushes Paradise Lost burst ceilings further when paired with optimized sigils and Master Traits. Seofon's Spada di Vento enhances Tempesta ATK↑ stacking under the July 15 skill rename. Tweyen's Bow of Eternal Splendor benefits ranged teams in Chaos co-op where Summon gauge sharing matters.

Frequently Asked Questions

Can I skip Stinger and go straight to Eternal Splendor?

No. Stinger forging is the intermediate step. Cycle 2 Refinium is strictly easier to farm than Cycle 4 Artifacts—do not skip tiers.

Do these weapons work in base game quests?

Yes. Once forged, they are equippable in all difficulties including retroactive base content.

Are special Crewmate Cards still required?

No as of Ver. 2.0.2. Two normal Crewmate Cards unlock Seofon, Tweyen, or Sandalphon each.
