Seth

• Preferred IV: +ATK or +SPD or +DEF / -RES

• Weapon: Slaying Edge (+Def) / Safeguard (+Def)

• Assist: Reposition / Player Preference

• Special: Blue Flame / Bonfire / Ignis

• Passive A: Steady Stance 4 / Atk/Def Bond / Sturdy Stance

• Passive B: Quick Riposte / Renewal

• Passive C: Atk Smoke / Cavalry Buff / Player Preference

• Sacred Seal: Atk/Def Bond / Quick Riposte / Close Def

With his good mix of stats, Seth can serve effectively as a frontline defensive tank, making him a strong wall against physical foes.

Either Attack, Speed, or Defense will work great as the Asset, helping Seth to either deal more damage, avoid more follow-ups, or sustain more attacks. For weapon, Slaying Edge makes for a fantastic weapon choice, helping Seth to utilize his Special more often. If one wants extra defensive capabilities, then Safeguard is also a great choice. In either case, refining it for Defense will help bolster Seth’s tanking even further. The Assist slot is mostly a matter of personal preference, with Reposition being a safe option. Blue Flame is an amazing Special and works fantastically for Seth, granting a flat 25 damage boost whenever he’s adjacent to an ally, though be aware that the damage boost is reduced to 10 whenever he has no adjacent ally. For much cheaper alternatives, both Bonfire and Ignis work very well and activate off of Seth’s high Defense.

Steady Stance 4 is a perfect fit for this build, giving Seth a huge Defense increase as well as preventing the opponent from charging their Special on Enemy Phase. Steady Stance 3 is also a good skill to use here, but without the Guard effect, it loses a lot of appeal. Atk/Def Bond is another strong option, granting a strong Attack and Defense boost to Seth whenever he has an adjacent ally, making it a natural fit with Blue Flame. Sturdy Stance is also a good option, granting extra Attack and Defense whenever attacked. In the B slot, Quick Riposte guarantees Seth with a follow-up attack whenever he is attacked while above 70% HP, helping him greatly with his KO potential. Renewal is another good option, helping Seth to stay healthy through some self-healing every other turn.

The C slot can be switched for personal preference. Atk Smoke is a great choice, helping to increase his sustainability against anyone affected. On a cavalry team, any Cavalry Buff such as Hone Cavalry will make a natural fit. Other than this, feel free to experiment. Finally, Atk/Def Bond will make for a fantastic Sacred Seal choice with a Attack and Defense buff whenever Seth has a adjacent ally. Quick Riposte is also a good option if he is not already using it as his B slot. Close Def is also a nice choice, boosting his defensive capabilities whenever attacked up close.

• ​​​​​​Preferred IV: +SPD / -RES

• Weapon: Slaying Edge (+Spd) / Wo Dao+ (+Spd)

• Assist: Reposition / Player Preference  

• Special: Moonbow / Bonfire

• Passive A: Atk/Spd Solo / Swift Sparrow / Fury

• Passive B: Desperation / Chill Def / Chill Spd

• Passive C: Even Spd Wave / Cavalry Buff  

• Sacred Seal: Atk/Spd 2 / Speed +3  

Despite his seemingly mediocre offensive capabilites, Seth can actually become pretty strong when on the attack.

For this, Seth will ideally want a Speed Asset in order to maximize his follow-up potential. Attack also makes for a good secondary choice of Asset. As for the weapon, both Slaying Edge and Wo Dao make for great choices. Slaying Edge reduces Seth’s Special cooldown by one while Wo Dao increases Special damage by 10. In either case, refining for Speed is the best option in order to further increase follow-up potential. The Assist is open to player preference and anything can be really used. Reposition is a great and safe choice for cavaliers. For Special, Moonbow is a great choice as with Slaying Edge, it’ll typically activate on Seth’s second attack with or without Desperation. Bonfire is also a great choice, though it won’t always be ready to go on Seth’s second attack if he’s using Desperation.

Atk/Spd Solo is an excellent A slot skill choice that grants Seth with a large offensive boost whenever he does not have any adjacent allies. As he’ll often be charging ahead to attack, utilizing this skill will typically not be too hard. If activating Atk/Spd Solo is of concern, Swift Sparrow is also a great choice, granting a lesser offensive boost, though with the only requirement being to initiate combat. For a budget option, Fury works great and gives Seth an all-around combat boost. Desperation makes for a great B slot choice, allowing Seth to make any follow-up attack instantly when he’s below 75% HP. Chill Skills such as Chill Def and Chill Spd also make for great choices, helping Seth against anyone affected with more damage or greater follow-up potential.

Utilizing a Spd Wave skill in the C slot will allow Seth to sustain himself with Speed buffs. Either Odd Spd Wave or Even Spd Wave would work fine. However, this is absolutely not necessary for this build to function well. If Seth can be provided with buffs from allies, Waves are not needed. If on a cavalry team, having a Cavalry Buff such as Hone Cavalry is recommended. Atk/Spd 2 makes for a great Sacred Seal choice, giving Seth one last offensive push. Simply Speed +3 also works.

• Preferred IV: +SPD or +DEF / -RES

• Weapon: Silverbrand (+Eff)

• Assist: Reposition / Player Preference  

• Special: Bonfire / Ignis

• Passive A: Fury

• Passive B: Chill Spd / Chill passives / Quick Riposte

• Passive C: Atk Tactic / Def Tactic / Res Tactic  

• Sacred Seal: Def Tactic / Res Tactic

With his new personal weapon, Seth can make for a very effective support unit.

Silverbrand is Seth’s personal and is what enables this build to be so effective. While it is not a great combat weapon, it is excellent support as the refined version provides the rare Spd Tactic skill. He can then combo with which anyone’s own choice of other Tactic skills in the C slot and Sacred Seal slot. The recommended combo is Atk Tactic in the C slot and Def Tactic in the Sacred Seal slot. This is also the cheapest combination of the lot. Regardless, any combination of the three remaining Tactic slots will work great.

To further support his supportive capabilities, Seth can utilize his B slot as such. Chill skills are great choices, allowing Seth to debuff the opponent with the highest value in the stat that the Chill skill affects. Chill Spd is the safest general choice as most units will benefit from the fastest enemy having less Speed, but any Chill skill can work fine.

The remainder of the build is to give Seth some combat utility for whenever it is needed. As he’ll mostly be used for support, Seth’s Asset and Flaw matter less here. Still, Speed will help to keep him safer from follow-up attacks, so it makes a natural fit. Any Assist can work fine, with Reposition being a great general choice for cavalry. Either Bonfire or Ignis will work great as the Special, both activating off of Seth’s good Defense. Fury is the recommended A slot as it’s cheap and provides a solid all-around boost to Seth’s combat potential. If the B slot is not being used for a Chill, it can instead be used for something to further enhance Seth’s combat abilities, such as Quick Riposte in order to guarantee him follow-up attacks when above 70% HP on Enemy Phase.
