Passive C: Joint Drive Spd / Pulse Smoke

Sacred Seal: Mystic Boost / Atk/Spd Solo / Spd/Res Solo / Quick Riposte

Young Eirika comes plentifully packaged from the get go to serve as a highly effective Aether Raids Tank. Only a couple of changes and some optional additions are even needed. With Blade of Renais being as loaded in effects as it is, she can easily do lots of damage and sustain herself through combat.
Eirika will want either an Attack or Speed Asset. Attack is the preferable of the two to boost her damage output, but Speed will also help her to secure follow-ups without relying on Quick Riposte. Recommending a Flaw is very hard since she wants all her stats, though Defense is her arguably best choice here.
Luna is a perfectly fitting Special and does not require change unless personally desired. Thanks to Blade of Renais having in-built healing, she doesn’t require a healing Special.
Due to the frequency of enemy mages on AR Defense teams, Distant Counter is superior to Distant Foil. If one has no Distant Counter available, then Distant Foil can still work, but care will be needed if powerful enemy mages are present.
Due to Young Eirika’s Duo Skill, she can enjoy both damage reduction and Null Follow-Up. The damage reducing B slots are still great options to consider though, since Duo’s Hindrance can interfere with Young Eirika substantially. Spurn is the strongest of the damage reducing B slots, but Repel and Close Call are still both strong.
Joint Drive Spd is a fitting C slot and doesn’t need change. Pulse Smoke is also worth considering to help shut down defense teams that rely on Pulse skills to charge Specials.
Young Eirika has several Sacred Seals that work very well with her. Thanks to her high Speed and default Null Follow-Up, Quick Riposte is not needed. Mystic Boost will help to protect against enemy staff users using Wrathful Staff, as well as provide some extra healing. A Solo skill like Atk/Spd Solo or Spd/Res Solo will also be excellent.
- If one swaps out Null Follow-Up for a damage reducing B slot, then Quick Riposte will be a fantastic Sacred Seal as it will allow her to perform follow-ups through Impact skills.

Strengths

Blade of Renais

Young Eirika’s personal weapon, Blade of Renais, is a Slaying weapon so loaded with effects that you have to wonder why Eirika ever decided to bother with using Sieglinde.

Firstly, it grants an all-around stat bonus if Eirika initiates combat or is within two spaces of an ally. A good bonus with an easy requirement for Aether Raids where support units should never be far behind.

Secondly, if Eirika has any bonus or penalty, she’ll deal damage equivalent to 20% of foe’s Defense. This extra damage is true damage and given that it’s common for high Defense foe’s to be present in AR defense teams, this is a nice damage bonus for her. In addition to this, if Eirika simply hits her opponent while a bonus or penalty is active, she’ll heal for 20% of Foe’s Defense. This allows her to forego the need to use a Special that heals, thus helping her damage output even more.

Dodge Duo Skill

Young Eirika’s Duo skill grants herself and nearby allies with Dodge. Dodge is functionally the damage reduction component of Spurn and similar skills, granting up to 40% damage reduction the more Speed that the user has than the enemy. With the Duo Skill resetting every odd-numbered turn, Eirika can use this frequently and can effectively forego a damage reduction B slot. Alternatively, this Duo Skill and damage reduction B slots will stack for even more damage reduction.

Amazing Stats

Young Eirika possesses a statline that puts her older self to complete shame. She has an outstanding offensive statline of 36 Attack and a blistering 43 Speed. On top of this, her defensive statline does not suffer for this offensive prowess, coming with 40 HP, 30 Defense, and 28 Resistance. All this is further supplemented by Blade of Renais thanks to its first effect.

Weaknesses

Duo’s Hindrance Exists

As with any Duo Hero, the presence of the Duo’s Hindrance structure can be detrimental. With Young Eirika having damage reduction on her Duo Skill, this structure is even more notably detrimental for her. Damage reduction is extremely beneficial for Aether Raids, so missing out on her Duo Skill hurts a lot

Duo Skill

Grants【Dodge】to unit and allies within 3 rows and 3 columns centered on unit.

Once used, Duo Skill cannot be activated again right away. At start of odd-numbered turns, if Duo Skill has already been used, unit can use Duo Skill again.

【Dodge】 If unit's Spd > foe's Spd, reduces damage from attacks during combat and from area-of-effect Specials (excluding Røkkr area-of-effect Specials) by percentage = difference between stats × 4 (max 40%).
