|This build is for players who wish to use Eldigan right out of the gate, as he thankfully doesn't need the fancier, elusive skills to thrive. In fact, a lot of Eldigan's skills here are quite flexible, and he can work well with various options, which will each be listed in their appropriate sections, which will also help depending on which mode he's in. Generally however, these skills will help Eldigan thrive on the player phase, as they take advantage of the HP drain that Fury provides.
Weapon: Mystletainn is Eldigan's weapon of choice. It hastens the Special charge, and when given its special effect, it grants Eldigan the Fury 4 skill, boosting his overall stats but injuring him for 6 damage after combat. This helps improve overall combat performance, giving him extra defenses to take a hit, and more attack to assail his foe.
Assist: Reposition is a good Assist in general to use. Its uses are versatile, as it can either help bring an ally closer to the fray, or bring an ally out of danger. Cavalry units put it to great use with their high Mov.
Special: Bonfire is a good Special for Eldigan to use, as it works well off of his great Def stat. His sword will bring its charge down to 2, letting him activate it pretty quickly. However, other Specials can be considered depending on the player's preference. Draconic Aura is another good option as Eldigan will also have high Atk to take advantage of, and should he opt for Life and Death 4, then this Special will work well instead of Bonfire. Glimmer is another good choice, as its charge is so fast that he should be activating it every other attack at the least. If he's given the Heavy Blade 4 Seal, then high charge Specials like Galeforce or Aether could be considered, with the former letting him take advantage of an extra turn, or the latter to help improve his sustain should the player feel like not always keeping Eldigan in peril.
A Passive: Fury 3 is Eldigan's A skill. It stacks with his Mystletainn's effect, meaning he's basically got a free +6 to all stats at the cost of 12 HP after each round of combat. The goal of this build then, is to take advantage of skills that require the user to be in peril. Life and Death 3 is an alternate option should the player wish to try and make Eldigan faster at the cost of his bulk, and it'll also make him stronger as well. He will lose out on the extra HP drain from the second Fury, but if he can comfortably exchange blows with an opponent, he should still be at low health for the skills needed for it, or his Mystletainn's Fury will eventually bring him down to 1 HP anyway.
B Passive: Desperation 3 is an option for Eldigan's B skill, which lets the user's follow up attacks to be performed immediately after if the user's HP is low enough. It pairs perfectly with the Brash Assault 3, and in an ideal scenario, Eldigan will be able to use this to strike twice and strike hard against many opponents before they can even react. Other options for the B skill slot include Vantage 3, as Eldigan will likely be at low enough HP, which can let him get the jump on an enemy. This could be effective, especially if there are no ranged enemies around and if Eldigan has a Special ready. While much more situational, Escape Route 3 could be fun to try, which could let him warp around the map to either get back to safety more quickly, or to potentially surprise a foe.
C Passive: Fortify Cavalry is an option for Eldigan's C skill if he's used on a cavalry team, letting him bolster the bulk of his cavalry allies. However, this skill slot is ultimately flexible, open to be any other buffing skill or any other skill, depending on the player's discretion and team composition.
Sacred Seal: Brash Assault 3 is Eldigan's Seal, which pairs well with Desperation 3 as his B skill. It lets him perform a follow up attack if he's at a low enough HP and his opponent can counterattack. With Desperation active at the same time, his follow up attack will occur immediately, and ideally, he'd be able to strike twice against an opponent before they can even react. As for other options, Heavy Blade 3 is a great option as Eldigan's Atk will be quite high, which can be heightened further with buffs. This will let him fire off his Specials faster, and with his sword already hastening the Special charge, he can make effective use of higher charge Specials like Galeforce and Aether quite well. Finally, one can never go wrong with simple stat buffs like Attack +3 or Speed +3.
