Eliwood

(Note: This is my Resplendent Eliwood with stat boosts. I also used Swift Sparrow 4, but it didn’t show up as an option.)

This build primarily revolves around Eliwood initiating combat. When he does, Swift Sparrow, Blazing Durandal, and Sturdy Blow bring him up to 59 Atk, 39 Def, and 46 Spd. Adding Galeforce onto that, he can get that twice in a row in a single turn. And if that’s not enough, Chill Def helps him wipe out bulkier units.

Mixed phase attacker. On player phase can easily take out almost any unit with glacies off of his high res, while not dying to any strong physical attackers with the effect of blazing durandal.
On enemy phase he can easily tank dragons of any colour and non blue mages. Lull spd and defence ensures he always has decent damage and speed without needing to invest in them too much, so that he can invest more into his defensive stats.

There would normally be special spiral in the b slot but it doesn’t seem to be there
Eliwood becomes an incredible galeforce unit with a little bit of investment and this is the investment he’s worth!

Eliwood, Knight of Lycia.
Now I shall present a build of an underrated unit. But before that, intro..

Eliwood.
His base stats on +0 is actually kinda disappointing, in cause of his very mediocre SPD, low DEF for an offensive unit, and a so-so ATK. But since there is an availbility for Eliwood to wield Blazing Durandal, which is Brave Roy's default weapon that just got its refine recently, he could even compete with many Gen 3 units and bulky blue units. And gave him a bit light to be shone.

This build focuses on hitting and running with Galeforce.

Note : I actually wanted to put Lull Atk/Def on the B slot but it is not available on this current Builder

Weapon : Blazing Durandal (Efficiancy)
This weapon focuses on gaining more bulk and speed, preventing follow-ups, +1 cooldown charge, and halting foes' cooldown charge during Eliwood's player phase.
If it is compared to the original Durandal's refine, this one is better for Galeforce since Durandal generates too much ATK and lesser SPD to perform Galeforce well, yet Blazing Durandal already includes Heavy Blade on it, so this opens better options for the Seal slot.

Assist : Repositon (Alternate : Swap)
This section is optional, you may fill it with anything depending on your needs.

Special : Galeforce
Every hit and runner's blood and flesh, this is required for hitting and running with proper means.

A : Swift Sparrow 3 (Alternate : Brazen Atk/Spd 3, Swift Sparrow 2)
This is his main offensive power, he needs additional atk or even spd during the combat, Swift Sparrow 2/Brazen is alright if you dont have SS3.

B : Hit and Run (Alternate : Lull Atk/Def)
With this, he can remove himself from enemies' range while initiating the combat and activating the Galeforce by backwarding himself by one space cardinal to the direction where he attacks.

C : Savage Blow (Alternate : Def Smoke, Atk Smoke)
This slot is somehow flexible, depending on your needs.
But Savage Blow is really helpful for inflicting outside damages to the nearest enemies within 2 spaces, so he could defeat thick units by dealing outside damages slowly.

S : Brazen Atk/Def (Alternate : Sturdy Blow)
He needs even more ATK (but not too much) and more defenses so he could survive from some deadly high damager units during processing the Galeforce.

That is all, I hope you like it.

This is my +10 Eliwood's current set, and it breathed some new life into him after his original refine.

The crux of this set is the combination of Blazing Durandal and a damage scaling special like Glacies or Ignis. I prefer to run Glacies because Eliwood's visible resistance is the superior stat, so on the off chance he has to take a hit in enemy phase, his special still has some kick. Ignis would be more powerful with investment however.

As for skills, Swift Sparrow 3 is by far the most optimal skill for this build, but is still a very expensive skill at the time of writing. As a result, Swift Sparrow 2 works perfectly fine on a budget. Chill Def is used to help make up for the loss of power over the original Durandal, though the B slot is actually pretty flexible here. I don't recommend running Desperation here as it defeats the purpose of the build, and the refine already gives Eliwood a much needed +10 defense. The C slot is also flexible; I prefer to run Atk Ploy to help soften up the hits that Eliwood may have to take. The seal slot is basically a toss up between Darting Blow and Sturdy Blow (the closest equivalent to a Death Blow seal at the time of writing). I prefer Darting Blow so Eliwood still retains his ultimate speed, but Sturdy Blow also gives Ignis a leg up over Glacies. IVs are also a toss up. I prefer to have Eliwood above 50 speed on initiation, hence a speed boon, but an attack boon is also devastating, especially if combined with Sturdy Blow.
