Fjorm

This is a pretty niche Fjorm build. Her role is to bait mages and retaliate back with a more offensive spread. This set is actually more effective with -HP +Spd

LnD gives her the needed offensive stats while preventing her from getting doubled. And It works well with Ice Mirror. With lower defenses, she can increase her special damage output.

Shield Pulse goes well with Ice Mirror. This makes Fjorm able to take a hit right away and kill a mage on the first turn.

With this set she can reach
Neutral total: 39/35/39/25/29
Summoner Support: 44/37/41/27/31

For S skills, you can put anything you need. If you have trouble tanking melee heroes, then put CD. Or maybe Deflect Magic to counter some Reinhardts (any Reins without Lancebreaker). Or even Speed+3 to double and prevent getting doubled

Well there's not much to explain Fjorm has good Def. In its general state, at the moment when we give it clear this. But we can improve your statistics combining with another Fjrorm if there is luck I had some luck and barely manage to get 1 upraising your HP stats from 39 to 40 and your Atk from 46 to 47.

And good because Close Defense? Certainly you can put perfectly distant Defense but not having an Celica to bequeath ability I decided to sacrifice Joshua that is obtained in the current event of storm. And I think that the sacred seal of distant Defense gave it away in a past event of storm, it is only a matter of leveling up with the new forging. This unit combined with
Any other that always this your side giving a buff of Def + 4 will match your def with your Res and with the defenses Close and distant are on par supporting so large amounts of damage is just a matter of having someone like Marth, masked Marth , Chrom, anyone who carries a Falchion and with the ability B Renwal to be spending life with ardent sacrifice as an offensive support, you can also choose to change the Special Glacies by Aether for more sustenance

Bueno no hay mucho que explicar Fjorm tiene buenas Def. en su estado general, al momento en que nos la regalan claro esta. pero podemos mejorar sus estadísticas combinándola con otra Fjrorm si hay suerte yo tuve algo de suerte y apenas logre sacar 1 subiendo sus stats de HP de 39 a 40 y su Atk de 46 a 47.

y bueno porque Def. Contigua? ciertamente se puede poner perfectamente Def. a Distancia pero al no tener una Celica para legar habilidad decidí sacrificar a Joshua que se obtiene en el actual evento de tormenta. y creo que el sello sacro de Def. a Distancia lo regalaban en un pasado evento de tormenta, solo es cuestión de subirle de nivel con la nueva forja. esta unidad combinada con
cualquier otra que siempre este su lado dándole un buff de Def + 4 igualara su Def con su Res y con las Defensas Contigua y Distancia estarán a la par soportando asi grandes cantidades de daño solo es cuestión de tener a alguien como Marth, Masked Marth, Chrom, cualquiera que porte una Falchion y con la habilidad B Recuperacion para estarle pasando vida con Fervor Aboluto como support ofensivo, también se puede optar por cambiar el Special Glacial por Eter para mas sustento

Fjorm's best set will need time to see. Her default set lets her perform as a blue res tank which is pretty rare in this game, only other one is Lute who's recent. She can first turn bait and kill frail blue and red mages, but she prefers to be attached to a partner and who's perfect but for Arvis and his Atk/Def ploys. Reposition is the only skill she needs, or triangle adept 2/3 for slot A which she needs for red swords.

Purely defensive build. I do not expect this to be anything amazing, but I did find this to be a great bait/tank build. With both close and distant defenses, Fjorm is able to take a hit and send some pain back. I looked at replacing Shield Pulse 3 with Renewal 3, but I believe the benefit of Shield Pulse out ways the benefit of 10 health every two turns.
The idea here is for Fjorm to bait/tank a hit(s) and then the rest of the team moves in on the next turn. Especially if Fjorm is boosted before defending, she will barely take any damage. Even without taking into account Ice Mirror or Shield Pulse, she only loses 6 fights in the FEH damage calculators when defending! Since a lot of the dangers in the current meta come from ranged attacks... she is a Beast.

I was a little surprised to not see this on the page. If anyone else already thought of this, sorry, I did not see your build.
Enjoy.

If you really like Fjorm as a character and a unit then this is the build for you as it takes full advantage of Ally and Summoner support. With the right team buffs she can survive almost every ranged unit in the game and if you couple it with buffs such as Performing Azura' s Sing? Owh boy you're in for a fun ride.

Her Legendary Weapon allows you to hit units that are attacking you regardless of distance and is amazing at baiting mages, dagger units, and many of the bow units. So we will be sticking with it for this build.

You want Fury to boost both your offensive and defensive stats. Coupling it with the Distant Def 3 Seal will make sure that 95% of the ranged units in the game won't one shot you, and you'll survive most of them with decent amount of HP to go for the kill and reposition yourself out. And yes, you can destroy Reinhardts.

Quick Reposte 3 makes up for her average speed by allowing you to bring the pain to every ranged unit that isn't Brave Lyn, a firesweeper bow unit, or the new and awesome Dazzling Staff+Wrathful Staff healers. Having one yourself means that you'll always be in range of Quick Reposte 3.

Def Ploy 3 uses Fjorm's massive Resistance to full effect and boosts your damage even further by lowering the opponent's defense in a cardinal direction.

Lastly Iceberg and Reposition for the big damage and the great mobility. Iceberg allows Fjorm to deal big damage to whatever hits you after charging it thanks to her amazing Resistance and you'll charge it quite easily. If you're confident in your team support then you can swap Iceberg for Glacies.

Overall Fjorm is a great F2P unit and a really strong addition to many teams if built to take full advantage of all your resources. Her water buff is neat too but good luck getting those blessings.
