Eirika

Weapon: Sieglinde (+Eff)

Assist: Reposition 

Special: Noontime

Passive A: Distant Counter

Passive B: Spurn / Repel / Close Call

Passive C: Joint Drive Atk / Joint Hone Spd / Spd Tactic

Sacred Seal: Quick Riposte / Distant Def

• This set is designed to maximize Eirika’s effectiveness in Aether Raids Offense. It will be most effective when paired with strong support such as Kaden or Brave Lucina. Kaden in particular synergises amazingly with Eirika due to both utilizing visible buffs.
• Both Attack and Speed make for strong Asset choices. Attack will naturally aid in Eirika’s ability to defeat opponents while Speed helps her to avoid follow-up attacks and activate Spurn or a similar B slot.
  • Ideally, Eirika should be merged for max effectiveness in this role. But in case she’s unmerged, HP would be the overall best Flaw choice.
• Distant Counter will be a necessity due to the prevalence of ranged foes found commonly on defense teams. Spurn will help to keep Eirika safe and also deal extra damage with her Special. Noontime is the desired Special due to the low cooldown and healing.
  • Spurn is strictly superior to Repel and Close Call, but both of these skills can still be used effectively if Spurn is unavailable.
• Since Eirika will typically be in range of her support allies, Joint Drive Atk is a perfect C slot choice for helping her to deal more damage. Otherwise, other buff skills like Joint Hone Spd or Spd Tactic make for fine choices, particularly when supported by Kaden.
• Due to Speed stacking being a common tactic, Quick Riposte in the Sacred Seal slot helps Eirika to ensure follow-up attacks while she’s healthy. If this is unavailable, Distant Def can be another great choice that helps keep Eirika safer against ranged foes.

Weapon: Sieglinde (+Eff) 

Assist: Rally Assist 

Special: Aether / Ruptured Sky

Passive A: R Duel Infantry 3 / Distant Counter

Passive B: Null Follow-Up / Def/Res Ruse  

Passive C: Joint Drive Atk / Joint Hone Spd / Spd Tactic

Sacred Seal: Drive Atk / Spd Tactic 

• This set is designed to be used in Arena, maximizing Eirika’s scoring potential while also maintaining good combat and support capabilities. Naturally, as many high SP skills as possible are desired.
• Her IVs have no affect on her arena scoring bin. As such, her Asset is free to choose between Attack and Speed to either help with dealing damage or help with securing and denying follow-up attacks.
  • Eirika should be merged if used in Arena, so the Flaw will not be of concern. Focus on getting the desired Asset.
• Any of the high SP rally skills such as Rally Spd/Def+ or Rally Up Res+ can work, though do note that Sieglinde has Hone Atk built in, so aim for a Rally skill that doesn’t also boost Attack. For Special, Aether and Ruptured Sky both make for strong options.
• R Duel Infantry is ideal for the BST bin bonus it gives, though the actual combat application of this skill is far more limited. If unavailable, Distant Counter will be a strong alternative option to allow Eirika to counter opposing ranged units.
• Null Follow-Up is a strong B slot option, allowing Eirika to more easily fight enemies that may rely on guaranteed follow-ups or follow-up negation, such as armored foes. Ruse skills are other good options to bolster Eirika’s support potential.
• A variety of strong high scoring C slots are available, such as Joint Drive Atk and Joint Hone Spd. If no 300 SP options are available, then there are still a variety of strong 240 SP options like Tactic skills.
• At time of latest update, no 300 SP Sacred Seals are available. As such, one is free to choose how to use this slot. Further boosting Eirika’s support capabilities through Drive or Tactic skills is a great idea.
