Unlocking Tweyen in Endless Ragnarok

The Endless Ragnarok expansion has arrived, bringing two Eternal characters into play: Seofon and Tweyen. If you’ve been searching for “Endless Ragnarok how to unlock Tweyen”, this guide is for you. We’ll cover everything from prerequisites to farming strategies so you can add the bow master to your roster as quickly as possible. The key to Endless Ragnarok how to unlock Tweyen is collecting Supreme Weapon Essence, and we’ll show you the most efficient ways to do it.

What You Need Before You Can Unlock Tweyen

Before you can even attempt to recruit Tweyen, you must meet a few critical milestones. These requirements are non-negotiable and serve as the foundation for the entire unlocking process.

Requirement Details
Campaign Completion Finish all main story quests up to the final boss
Proud Difficulty Clear all Extreme and Maniac quests to unlock Proud
Knickknack Shack Unlocked after beating the main campaign
Items Needed 3 Supreme Weapon Essence OR 90 Revenant Medallions

Once you’ve cleared the main campaign and see Proud difficulty at the quest counter, head to Siero’s Knickknack Shack in town. Under the “Treasure Trade” menu, you’ll find Special Crewmate Cards for both Seofon and Tweyen. Each card costs 3 Supreme Weapon Essence. But don’t worry if you can’t farm the highest-tier quests immediately — there’s an alternate path using Revenant Medallions.

How to Farm Supreme Weapon Essence: Two Proven Methods

Farming Supreme Weapon Essence is the central challenge in Endless Ragnarok how to unlock Tweyen. Based on community experience and the game’s design, two quests stand out as the most reliable sources.

Method Quest Difficulty Drops Recommended For
Supreme Weapon Essence (direct) Lock Horns Proud Random drop (approx. 1 per 2–3 runs) Players with strong builds and high gear
Revenant Medallions (trade) Gulp… So These Are the Rumored Monsters Extreme 1–2 Medallions per run (30 needed per Essence) Players who prefer a safer, slower grind

Direct Farming: Lock Horns (Proud Difficulty)

Lock Horns pits you against a behemoth enemy with many area-of-effect attacks. This quest is the fastest source of Supreme Weapon Essence if your party can handle the damage output. According to player reports, the drop rate is generous enough that a few hours of dedicated runs will net you all three essences you need.

  • Party Composition: Bring characters with debuff immunity or high defense. A healer like Katalina or a tank like Eugen can make the fight much more manageable.
  • Co‑op: If you’re struggling, jump online. The quest is always active, and veteran players frequently run it. You’ll often clear it faster with a full group.
  • Break Parts: Focus on breaking the behemoth’s parts for additional loot chances — these can sometimes yield extra Supreme Weapon Essence.

Alternative Route: Revenant Medallions from Extreme Quests

If you’re not yet strong enough for Proud content, or simply prefer a more gradual approach, you can farm Revenant Medallions from the Extreme quest Gulp… So These Are the Rumored Monsters. Each run gives 1–2 medallions. You need 30 medallions to trade for one Supreme Weapon Essence, or 90 medallions to trade directly for a Special Crewmate Card.

  • Why do this? It’s easier, less gear‑dependent, and can be completed solo without too much stress.
  • Downside: It takes significantly more runs — typically 45–90 runs depending on medallion drops.

Step-by-Step: Unlocking Tweyen

Follow these steps to add Tweyen to your party. The process is identical for Seofon, so you can apply the same strategy for both characters.

  1. Complete the main campaign and unlock Proud difficulty.
  2. Open Siero’s Knickknack Shack and navigate to Treasure Trade.
  3. Check the Special Crewmate Card for Tweyen. It costs 3 Supreme Weapon Essence.
  4. Farm Supreme Weapon Essence using either Lock Horns (Proud) or the Revenant Medallion trade route.
  5. Convert 90 Revenant Medallions into 3 Supreme Weapon Essence (if you choose the alternative route) by trading at Siero’s.
  6. Trade 3 Supreme Weapon Essence for the Special Crewmate Card.
  7. Use the card from your inventory to unlock Tweyen permanently.
Item Quantity Converts To
Supreme Weapon Essence 3 1 Special Crewmate Card (Tweyen)
Revenant Medallion 30 1 Supreme Weapon Essence
Revenant Medallion 90 1 Special Crewmate Card (direct)

Tweyen Overview – Why She’s Worth the Grind

Tweyen is a Wind element character with a Balanced combat style and Bow weapon specialty. Her passive, Ultrasight, charges up to 10 levels as she lands attacks and skills. At maximum level, her abilities deal significantly extra damage. She excels at applying debuffs and punishing enemies from a safe distance.

Key Skills

Skill Type Effect
Clincher Offense Fires a single powerful arrow; damage scales with the number of debuffs on the target
Depravity Offense Rapid arrow volley; hold to inflict ATK↓, DEF↓, Burn, Poison, and Slow
Two Crown’s Strife Utility Extends the duration of debuffs inflicted on enemies
Peerless Eye Defense Grants Stout Heart (poise) and Deadshot (guaranteed critical? – community notes suggest it boosts accuracy/critical chance)
Dark Huntress Passive Holding attack allows lock‑on to multiple targets based on Ultrasight level
Bring the Thunder SBA Buff After using Skybound Art, skills deal increased damage and inflict Paralysis
Combo Result
Depravity → Two Crown’s Strife Inflicts multiple debuffs and prolongs them, maximizing Clincher’s bonus damage
Build 10 Ultrasight stacks → Clincher Massive single-target burst; the core of Tweyen’s damage rotation

Weapons (Max Awakened stats)

Weapon HP ATK
Bow of Dismissal 2575 2003
Desolation-Crown Bow 4091 4211

The Desolation-Crown Bow is her best‑in‑slot weapon, offering significantly higher HP and ATK. It can be obtained from high‑level missions or the Knickknack Shack after meeting certain requirements.

Tips for Speeding Up Your Tweyen Unlock

  • Use online co‑op for Lock Horns. You’ll clear it faster and possibly get help from players who already have Tweyen.
  • Focus on survivability first. If you die too often, your farming efficiency plummets. Equip sigils that boost HP, defense, and auto‑revive.
  • Save your medallions wisely. If you plan to unlock both Eternals, you’ll need 6 Supreme Weapon Essence total (one for each). Start saving early.
  • Check daily quest rotations. Sometimes special events offer bonus rewards that include Supreme Weapon Essence or medallions.

Frequently Asked Questions

Can I unlock Tweyen without farming Supreme Weapon Essence directly?

Yes. The alternative method in Endless Ragnarok how to unlock Tweyen involves collecting 90 Revenant Medallions from the Extreme quest “Gulp… So These Are the Rumored Monsters.” You can trade the medallions for Supreme Weapon Essence at Siero’s, or convert 90 medallions straight into the Special Crewmate Card.

How long does it take to unlock Tweyen?

It depends on your method. With a strong party farming Lock Horns, you can gather 3 Supreme Weapon Essence in about 2–4 hours. Using the medallion route, expect 5–10 hours depending on your efficiency and drop luck. Player reports confirm that Lock Horns is significantly faster for those who can clear it consistently.

Is Tweyen automatically added when I buy the Endless Ragnarok DLC?

No. Even if you own Endless Ragnarok, you must still complete the main campaign, reach Proud difficulty, and gather the required materials. The DLC gives you access to the new quests and characters, but the unlock process remains the same.

What are the best sigils for Tweyen?

Tweyen’s damage revolves around debuffs and her Ultrasight system. Prioritize sigils that boost critical hit rate, attack power, and debuff success rate. War Elemental and Supplemental Damage are excellent choices. For survivability, add Stout Heart or Auto‑Revive. Many experienced players also recommend Quick Cooldown to keep her debuff rotation active.
