Resplendent Hero

Resplendent Attire has been released for Seth. With their Resplendent Attire equipped, they will have a different appearance, have new voice clips, and additionally, gain +2 to all stats. If you really like Seth or you want to make them stronger, you may want to buy a FEH pass and get the Resplendent Attire.

Seth Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) HP Superboon ★★★☆☆
Atk (24) No Attack IV ★★★★☆
Spd (7) No Spd IV ★★★★★
Def (8) No Def IV ★★★☆☆
Res (5) No Res IV ★★☆☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Spd/-Res

The best IVs for Seth are +Spd and -Res. A higher Spd stat allows Seth to get a ton of follow-up attacks on his foes which is very important for an offensive unit like him. His Res is of less importance so it is safe to take as a bane.

Arena Medal：500　Divine Dew：200

We recommend the Special Effect Refine for Silverbrand

The special effect refiine for Silverbrand grants effects identical to Spd Tactic 3. It allows Seth to both fit in all-cavalry teams and in mixed teams as well. +6 Spd is a huge buff and it is surely enough to secure lots of follow-up attacks on a wide range of foes.

Seth is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Def stat.

Seth Strengths

Very Strong Against Green Units

Seth's Ruby Sword+ and Silverbrand boosts his Atk by +20% if he gets into combat with green units. This allows Seth to deal with powerful green units with ease. This also makes Seth a valuable unit because the green attribute class is boasts some of the strongest units in the game, and he has the tools to easily take them out. However, this will make Seth very weak against blue units.

Built-in Spd Tactic 3 upon special refinement

Refining Silverbrand gives it the effects of Spd Tactic 3. Its effect allows Seth to give Spd +6 to his allies within 2 spaces for 1 turn, as long as there are no more than two of that ally's movement type on the team. This makes it easy for his allies to secure folow-up attacks, and is great for a mixed mobility party. You can read more about Silverbrand and its special effect refine here!

Great fit in cavalry-only teams!

With little investment, Seth is a great option in cavalry teams. He is great against green units and can inflict debuffs on opponents. Make sure to include skills such as Hone Cavalry and Fortify Cavalry into the mix to power-up your cavalry teams even further!

Atk/Def debuff on the opponent that fits his play style very well

Seal Atk/Def 2 inflicts -5 Atk/Def on Seth's foe after combat. This means he cannot take advantage of it on the first attack, but his allies can take advantage of this so make sure Seth attacks first. If he is refreshed by a dancer, he can enjoy it too.

The best way to use this is to bait enemies into attacking Seth in the enemy phase so that he can retaliate back in the player phase assuming he survives. If he is up against a green physical unit, he will most likely survive because of his naturally high Def coupled with the defensive effects in Silverbrand and Fortress Def 3. This sets them up for a very powerful blow from Silverbrand in the next player phase that they would not likely survive.

Seth Weaknesses

Very Weak Against Blue Units

The downside to Ruby Sword+ and Silverbrand is that it makes Seth very weak against blue units. He can be one-shot by most offensive blue units so pay attention to his positioning in relation to them, and leave them to Seth's allies so he can focus his firepower on other units.

Weak to Cavalry Effective Weapons

Seth takes 1.5x damage from cavalry-effective weapons like Ridersbane, and one blow from this type of weapon is sure to take him/her down. Make sure you know what weapons you are up against before hopping too far into the line of battle!

Lv 40 5★ Dialogue

Lv 40 5★ Dialogue become available when a hero attains Lv. 40 at 5★ rarity.

I must express my gratitude for your leadership. As a knight, all I ask for is an opportunity to serve.
However, permit me to say just one thing.
Feelings have no place on the battlefield. You issue orders. I obey them. That is all.
In battle, a life-or-death moment could come at any time. Emotions could cloud your judgment.
If my mind was on you instead of the opponent before me, that could end up costing us a victory.
So I must ask that you keep your distance. This will ensure that I can continue to protect you in the future.
