Signature mechanic

Avatar doubles his attack output

Seofon spends the Avatar gauge, filled by combo finishers, to summon a duplicate that attacks alongside him. While the avatar is active, further finishers raise his Swordshine level, which adds extra attacks on top. The rule that defines him is simple: only use skills while the avatar is out, because everything is worth roughly double there.

Seofon is a combo-heavy DPS that revolves around summoning his avatar to double his attack output. He has skills that give massive buffs, further improving his power, and is good to use against bosses. One of the best skills he has in his arsenal is the Seven-Star's Brilliance, which maxes out all SBA gauges, letting his team deal chained SBA frequently.— Game8 tier assessment

Support skills (passives)

  • Star Sword Sovereign

    Allows Seofon to consume the Avatar gauge to summon an avatar. Landing combo finishers fills the Avatar gauge.

  • Spirit Swords

    Seofon deals additional attacks based on his Swordshine level. Landing combo finishers while an avatar is summoned raises Swordshine level.

How to unlock

Seofon can be unlocked by trading 3 Supreme Weapon Essence for his Crewmate Card. This can be done via the Treasure Trade in Siero's Knickknack Shack .

Strengths

  • 1

    Enormous burst windows

    Avatar plus high Swordshine effectively doubles his output for the duration.

  • 2

    Excellent against bosses

    S tier, with self-buffs that make him one of the strongest single-target duellists.

  • 3

    Clear decision rules

    Complex to execute but conceptually simple — hold skills for the avatar window.

Weaknesses

  • 1

    Feast or famine

    Outside the avatar window his damage is ordinary, so poor gauge management wastes the character.

  • 2

    Finisher-gated

    Everything keys off combo finishers; interruptions cost you both gauge and Swordshine.

  • 3

    Paid unlock

    Requires Siero's Treasure Trade or a purchase rather than normal progression.

Sigil loadout — Fatebreaker

Seofon's sigils in Endless Ragnarok center around his Master Traits. To get the maximum value out of it, he specifically needs 5 Basic-Stat , 3 Attack , and 2 Defense or Support . This will provide him up to 200% Damage Cap , 100% Attack Boost , 6% Defense , and 20,000 base HP .

We recommend 2 Health and 3 Stun Power for his basic stat sigils. Equipping exactly one Greater Aegis and Aegis boosts his health to 180k–195k without disabling the Catastrophe Nova boost. For attack, always run Fatebreaker , Celestial Lumen , and Celestial Terra to raise his damage cap. Finally, use his defense/support slots for Improved Dodge (for better evades) and Steel Nerves (for damage reduction with Stout Heart).

Prioritize Supplementary DMG and DMG Cap subtraits to boost his damage, and fully utilize his Fury and Rally character-sigils in the endgame. Due to the existence of summon traits, Warpath is removed in this build. Run Uplift to build his SBA gauge faster, and slot in Guts , Potion Hoarder , and Autorevive for his survivability options. Quick Cooldown further reduces the cooldown of his skills.

Gearing priorities

  • Transcended Terminus (T.Lvl 7): Catastrophe Nova, DMG Cap, Sigil Booster, Unbound Master
  • While progressing Chaos, a transcended Defender weapon usually beats an un-transcended Terminus
  • The standard template: 5 Basic-Stat + 3 Attack + 2 Defense/Support sigils
  • Fatebreaker V+, Celestial Lumen V+ and Celestial Terra V+ in the attack slots
  • Improved Dodge+ and Steel Nerves V+ for survivability that does not cost damage
  • Summons for their traits: War Elemental, Stout Heart, Berserker Echo, Spartan Echo

Over Mastery bonuses

  • Skill Damage Cap Up
  • Stun Power Up
  • Normal Attack Damage Cap Up
  • Skybound Art Damage Cap Up

Once Seofon has all of his Weapon Transcendance Masteries fully unlocked, he will have 80%-82% Critical Hit Rate without any sigils, traits, or summons. Therefore, he only needs to enable one Master Trait that increases his Critical Hit Rate by 20% to reach 100%, which will give him more room for his Over Mastery Bonus.

Execution

Combos & rotation

  • Combo B Fueling the Avatar Combo (Endless Ragnarok)9 steps
    1. 1Immediately summon his Avatar at the start of battle, even if he has no Avatar gauge
    2. 2Cast Barrido to close the gap and gain Avatar Gauge
    3. 3Use Infinito Creare and Despedazar to gain more Avatar Gauge
    4. 4(Optional) If link attack is available, use it to gain significantly more Avatar Gauge and Swordshine level
    5. 5Execute a few Combo B until you have Swordshine level 3
    6. 6Use Tempesta to regain all your Avatar Gauge while giving Seofon a higher attack and critical hit rate up buff.
    7. 7Repeat Combo B while using the skills once it is available right away
    8. 8If all skills are on cooldown and Seofon is about to run out of Avatar Gauge, use Combo E to dismiss his Avatar with a finisher
    9. 9Immediately summon his Avatar again after one of his skills is available, then repeat the entire combo with a Swordshine level 1 right off the bat on his next summon.

    You can use Seofon's upgraded combo once he is at Master Trait level 30. The main difference is that his damage is significantly higher and his Avatar lasts longer in a fight as long as you can do combo finishers and skills constantly. If you executed the combo well while avoiding any damage, he should be able to resummon his Avatar at full gauge as soon as it expires.

    His Combo E move can be seen in Seofon's command list. You can do the move by using four normal attacks, followed by two unique attacks, and ending with a combo finisher to execute an avatar finisher when an avatar is summoned.

  • Combo B Tempesta Combo (Pre-DLC)5 steps
    1. 1Always start the fight with Tempesta to instantly gain max Avatar gauge
    2. 2Use Barrido to close the gap and damage the enemy
    3. 3Cast Despedazar and Infinito Creare to deal more damage
    4. 4Do Combo B until any one of Seofon's skills goes off cooldown, then immediately use it
    5. 5Repeat until you run out of Avatar gauge

    Seofon's best combo revolves around gaining Swordshine level as fast as possible using his skills and Combo B repeatedly. After you use 3 of his skills, you should be at level 2 Swordshine. A few Combo B will put you at level 3, which will enhance all of Seofon's attacks and skills going forward.

    His Combo B move can be seen in Seofon's command list. You can do the move by using two normal attacks, followed by two unique attacks, and ending with a combo finisher.

  • Only Use Skills When Avatar Is Active

    Once Seofon runs out of Avatar gauge, do not use his skills without it. Focus on gaining Avatar gauge by using Tempesta or executing any combo finishers. More than half of his Avatar gauge is enough . Recall his avatar by pressing his unique attack, then resume his combo.

  • Swordshine Level Enhances Seofon's Attacks

    Each Swordshine level enhances all of Seofon's attacks. He hits more and deals increased damage than his non-Avatar attacks.

  • Dodge In Between Combo B When Necessary

    You can dodge in between his attacks to avoid taking damage while preserving his combo finishers . Use this to your advantage to reposition yourself during battle, especially against agile bosses.

  • Use Link Attacks to Gain Avatar and Swordshine

    When Avatar is activated, the only way for Seofon to regain his Avatar gauge is to use a link attack. This is why Stun Power is important for him so that he can do link attacks often.

Kit

Skills

Recommended loadout — Barrido and Tempesta

Seofon utilizes both his normal attack combos and skills. It is best for him to have 3-4 offensive skills to take full advantage of his Avatar, which can enhance his skills. His Avatar gauge gain is slow, so make sure to use Tempesta to instantly grant him maximum Avatar gauge.

As for his offensive skills, Barrido is his gap closer that can deal a lot of damage and has a low cooldown. Despedazar launches small enemies it hits as well as deals multiple small AoE damage in front of him. Infinito Creare is his projectile skill that deals a high amount of small damage in an area. Use this skill only when the enemy cannot dodge it.
