Duo Eirika Builds
 : Blade of Renais | A :Distant Foil |
 : Reposition | B : Null Follow-Up 3 |
 :Luna | C : Joint Drive Spd |
| S : Sturdy Stance 2 |
A budget setup for Duo Eirika! Her kit is already very complete, so you only need a movement-assist skill and a Sacred Seal of choice. Sturdy Stance 2 is just one of the many options you can take and it synergizes well with the rest of her kit!
Recommended IVs
| +Spd/-Res | The best IVs for Duo Eirika are +Spd and -Res. A higher Spd stat allows Duo Eirika to get a ton of follow-up attacks on her foes. This also helps her effectively leverage the Spd-based damage reduction she gets from her Duo Skill. Her Res is of less importance, so it is safe to take as a bane. |
| +Spd for a +10 Merge | We recommend a +Spd IV when merging Duo Eirika to 10. This is for the same reasons as above! Maximize her Spd and she will be very bulky thanks to her Duo Skill. You can also get a +Atk IV if you prefer, but +Spd is arguably better in most situations. |
