Mia

Preferred IV: +SPD / -HP or -DEF or -RES

• Increasing Mia’s Speed is vitally important, as not only does the bonus damage from her refined weapon key off Speed, but it also helps her double speedier enemies.

Weapon: Resolute Blade (+Eff)

• With the new refine, Mia’s Resolute Blade now offers a plethora of boosts to her damage output, so much so that her relatively unimpressive Attack stat is much less of an issue.

Assist: Reposition

Special: Moonbow / Luna

• A low cooldown Special like Moonbow is ideal to allow Mia to activate it as much as possible to utilize the +10 damage from Resolute Blade as much as possible.

• Luna is a decent alternative if utilizing the Flashing Blade Seal, as it has a notable damage increase over Moonbow. Note that this is fairly risky as a lot of Mia’s damage is tied to her Special.

Passive A: Atk/Spd Solo / Fury (3 or 4)

• An offensive stat boosting A skill is ideal, particularly the ones that can work on both Player and Enemy Phase since Mia isn’t locked to either one. This makes Atk/Spd Solo and Fury particularly good options.

Passive B: Null Follow-Up / Wrath / Close Call / Desperation

• Mia’s B skill will play a major role in determining how she plays. Null Follow-Up is the best overall option, as it completely shuts down all skills that would otherwise prevent Mia from being able to double her opponent (assuming she has enough Speed).

• Wrath can be combined with the refined Resolute Blade to offer Mia a massive damage boost when her Special activates. All of the true damage boosts to Mia’s attacks will allow her to break through even the toughest physical defenders, but is liable to get shut down by enemies with skills like Wary Fighter or Swordbreaker.

• Close Call can drastically improve Mia’s survivability, both by reducing incoming damage by up to 40% as well as moving her a space away after attacking. If utilizing Close Call, then Mia can opt to run Player Phase-oriented A skills like Swift Sparrow since it’ll drive her focus in that direction.

• Finally, Desperation is a good budget option if none of the other options are readily available, as it allows Mia to safely double her opponents as long as she’s within the HP threshold (and isn’t being stopped by skills like Wary Fighter or Swordbreaker).

Passive C: Time’s Pulse / Flexible

• Time’s Pulse is an extremely high investment skill, but is very useful for Mia due to her big reliance on Specials for damage output. This is doubly important if Mia is running Wrath.

• If Time’s Pulse is unavailable, then it can be replaced with pretty much any C skill to suit the team.

Sacred Seal: Quickened Pulse / Darting Blow / Atk/Spd Bond / Flashing Blade

• Mia has a variety of options for her Seal that are dependent on the rest of her build. Quickened Pulse synergizes exceptionally well with Time’s Pulse to allow Mia to start with her Special charged, offering her a massive boost to her damage output.

• Darting Blow is a good general-purpose Seal, as Mia gets a lot of mileage out of increasing her Speed.

• Atk/Spd Bond can be a bit tricky to utilize due to the positioning requirement, but can potentially be very strong due to the excellent stat boosts.

• Finally, Flashing Blade is a strong option when paired with Desperation or if utilizing Luna over Moonbow.

This build is extremely reliant on having support from Brave Lucina with her refined Geirskogul for best performance. It’s possible to make it work without her, but there will be a significant dip in performance.

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

• Increasing Attack, Speed, or Resistance are all good options for Mia. However, any Flaw will be extremely detrimental for her in Aether Raids; if using Mia in Aether Raids, then it’s highly recommended to try to get at least one merge.

Weapon: Resolute Blade (+Eff)

• With the new refine, Mia’s Resolute Blade now offers a plethora of boosts to her damage output, so much so that her relatively unimpressive Attack stat is much less of an issue.

Assist: Reposition

Special: Noontime / Sol

• A low cooldown healing Special like Noontime is ideal for Mia to maximize her survivability in Aether Raids. Brave Lucina is extremely important to have for support here, as otherwise there will be a lot of delays between Special activations.

• If Brave Lucina is unavailable, then Sol is worth consideration since the timing will work out better.

Passive A: Distant Counter

• Being able to tackle both melee and ranged enemies is a vital ability for most Aether Raids units, and Mia is no exception.

Passive B: Close Call / Wrath

• Close Call is the primary reason why Mia is viable in Aether Raids; having a Speed-based source of up to 40% damage reduction hugely negates her otherwise unimpressive bulk, and allows her to potentially survive major damage threats. The Speed-based scaling also synergizes nicely with her refined Resolute Blade’s effect.

• If Close Call is unavailable, then Mia isn’t a particularly good choice for Aether Raids. However, Wrath can help her overall damage output and survivability by increasing her Special damage, though she still needs to worry about not getting immediately KO’d in the first place.

Passive C: Pulse Smoke / Atk Smoke

• For Aether Raids, Pulse Smoke is incredibly powerful for shutting down Infantry Pulse-based defense setups, which are some of the most threatening due to their extremely high damage output.

• If Pulse Smoke is unavailable, then Atk Smoke is a good budget option for increasing Mia’s overall survivability.

Sacred Seal: Swift Stance / Steady Posture / Fierce Stance

• Swift Stance and Steady Posture are both fantastic Seal options due to increasing both Speed and a defensive stat. Swift Stance is generally more useful for Mia due to her lower Resistance and the prevalence of magic damage threats.

• Alternatively, Fierce Stance can greatly boost Mia’s damage output, offering her a good chance of KO’ing her opponents in one hit. With the right support and setup though, Mia should generally have enough damage without it.
