Eirika

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

• Weapon: Sieglinde (+Eff)

• Assist: Reposition / Rally Resistance

• Special: Moonbow

• Passive A: Fury / Triangle Adept

• Passive B: Chill Spd / Swordbreaker

• Passive C: Spd Tactic / Hone Spd

• Sacred Seal: Def Tactic / Fortify Def

Eirika’s primary set is designed to maximize her support potential while having her also act as a strong combatant.

A Speed or Attack boon is ideal here. Speed helps Eirika to secure doubles as well as avoid double attacks while Attack gives her a very much appreciated boost in power. Both HP and Resistance make good choices for the bane. The refined Sieglinde is wanted not only to provide a higher Attack boost but also to allow Eirika to utilize her own boosts in case she needs to see combat. Your Assist should be either Reposition a Rally skill. Reposition allows Eirika to assist with unit positioning while a Rally skill will help with Eirika’s support potential. Moonbow makes for a fine Special as it helps Eirika to combat higher Defense enemies such as Hector.

Fury is ideal for Eirika’s A slot as it gives her a very beneficial boost in all areas, helping her both offensively and defensively. Triangle Adept is also a good option. While Eirika would be relegated to solely fighting green units, Triangle Adept ensures that she can handle any green unit coming her way. Chill Spd in the B slot makes for a great support option, allowing herself to not only buff the stats of her allies but also debuff the fastest enemy by seven speed. As an alternative, Swordbreaker ensures Eirika’s safety against strong sword threats such as Ayra and Mia as they’ll fail to KO her unless they activate their Special.

The bulk of Eirika’s support utility comes from her C slot and Sacred Seal. Her default C slot Hone Spd fits perfectly with this set, though if you have a team which enough diversity in movement types, she can utilize the superior Spd Tactic. While expensive, Spd Tactic is a perfect fit for Eirika and a flat upgrade over Hone Spd. For the Sacred Seal, Eirika can put Fortify Def to great use. With Sieglinde, Fortify Def, and either Hone Spd or Spd Tactic, Eirika can boost all the important stats for a melee unit all at once. However, if your team composition allows for it, Def Tactic is definitely recommended as it’s indisputably stronger than Fortify Def if it can be activated.

• Preferred IV: +ATK or +SPD / -DEF

• Weapon: Sieglinde (+Eff)

• Assist: Reposition / Rally Def/Res

• Special: Moonbow

• Passive A: Distant Counter / Fury / Distant Def

• Passive B: R Tomebreaker / Chill Spd

• Passive C: Spd Tactic / Hone Spd

• Sacred Seal: Distant Def / Fortify Def / Fortify Res

This Eirika set loses some buffing potential in exchange for the ability to act as an effective mage counter while still being an effective buffer.

Again, an Attack or Speed boon is desired. Attack gives Eirika a much needed power boost which helps greatly against enemy mages while Speed is also acceptable for more security from double attacks as well as better doubling potential in general. Since she’ll primarily be fighting mages, Defense makes for the ideal bane. The refined Sieglinde makes for the ideal weapon choice, not just allowing her to boost the Attack of her allies, but also benefit from the boosts that she provides to them as long as they’re within two spaces of her. For the Assist, Reposition allows Eirika to offer help with unit positioning. Alternatively, Rally Def/Res makes up for the loss of the Sacred Seal slot to a non-boost skill and offers a nice middle ground between boosting both Defense and Resistance. If Rally Def/Res is not available, simply using Rally Defense or Rally Resistance is acceptable. Moonbow is a good choice of Special due to the low cooldown, allowing it to activate consistently.

With Distant Counter and a Attack boon, Eirika can deal with the majority of popular green mages. Fury Nino, Fury Summer Elise, Fury Sonya, and Fury Deirdre will be OHKO’d by Eirika while Fury Julia will be ORKO’d by Eirika. Rhajat can barely survive thanks to her decent Defense and a Fury Rhajat can even survive with a Defense bane. If you are unable to sacrifice a Hector for Distant Counter, you could instead run something like Fury, Distant Defense, or simply Resistance +3 for reduced magic damage. This will, however, prevent you from countering mages on Enemy Phase which results in this set losing a large portion of its appeal. With R Tomebreaker, Eirika will be able to counteract red mages such as Celica who enjoy running Swordbreaker, thus preventing her from a ORKO against Eirika. Do take care though as +ATK Life and Death Swordbreaker Celica can still KO Red Tomebreaker Eirika if Ragnarok is active as she’ll double her naturally. If red mages are not of concern, Chill Spd allows Eirika to provide additional support by debuffing the Speed of the fastest opponent. Her default Hone Spd works perfectly for this set, but Spd Tactic is a superior option if your team composition allows for it.

As for Sacred Seals, Eirika will greatly enjoy having the Distant Def Seal, granting her with a nice defensive boost whenever she is attacked at range. This goes well with this set, allowing her to more safely bait mages into attacking her. One of the Fortify or Hone skills could also be used if one wants to boost all four stats without relying on a Dual Rally.
