Summer Mia Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (16)		★★★☆☆
Atk (21)		★★★★★
Spd (11)		★★★★☆
Def (4)		★★★☆☆
Res (6)		★★★☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units

Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Atk/-Res

The best IVs for Summer Mia are +Atk and -Res. Summer Mia is already fast and increasing her Atk would best maximize her damage potential. Her Res stat is already low and it is not really important for her so it is safe to take as a bane.

+Atk for a +10 Merge

We recommend a +Atk IV when merging Summer Mia to 10. This maximizes Summer Mia's damage potential because she already has very high Spd especially in the player phase where Swift Sparrow 3 can be triggered.

Summer Mia Best Weapon Refine

Effect of Summer Mia's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Summer Strikers	SP: 400
Might: 14　Range: 2　HP: Accelerates Special trigger (cooldown count-1). If unit initiates combat or if foe's Range = 2, grants Atk/Spd+5 to unit, reduces damage from foe's first attack by 75% ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes), and neutralizes effects that inflict "Special cooldown charge -X" on unit during combat. Effect: 【Dagger 7】 At start of turn, for unit and allies within 2 spaces of unit, if Special cooldown count is at its maximum value, grants Special cooldown count-1. At start of combat, if unit's HP ≥ 25%, grants Atk/Spd+5 to unit, grants bonus to unit's Atk/Spd = 20% of unit's Spd at start of combat, and neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks during combat. ：500　：200

We recommend the Special Effect Refine for Summer Strikers

Refined Summer Strikers grants 75% damage reduction on foe's first attack, Atk/Spd+10 during combat, bonus Atk/Spd during combat based on Mia's Spd, neutralizes effects that slow down Mia's Special cooldown charges, and a Null Follow-Up effect.

More importantly, refined Summer Strikers grants a Time's Pulse 3 effect to Summer Mia and all allies within 2 spaces. This effect opens up offensive strategies that focus on pre-charging Special skills, overwhelming enemy tanks with massive damage output.

Summer Mia Roles, Strengths, and Weaknesses

Summer Mia Roles

Mia - Harmonic Blades Roles
Close-Physical	Ranged-Physical	Close-Magic	Ranged-Magic
Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

Summer Mia is a ranged physical attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Def stat.

Access to a Harmonized Skill!

Summer Mia is the first of a new hero category, the harmonized heroes. They have access to a unique harmonized skill which is very similar to duo skills. You can activate harmonized skills by pressing the the harmonized skill button. Because this harmonized unit features both Mia and Masked Marth, they can qualify for bonus scores in all of the games where these two show up!

Summer Mia Strengths

Summer Strikers reduces team's Special cooldown

Refined Summer Strikers grants 75% damage reduction on foe's first attack, Atk/Spd+10 during combat, bonus Atk/Spd during combat based on Mia's Spd, neutralizes effects that slow down Mia's Special cooldown charges, and a Null Follow-Up effect.

More importantly, refined Summer Strikers grants a Time's Pulse 3 effect to Summer Mia and all allies within 2 spaces. This effect opens up offensive strategies that focus on pre-charging Special skills, overwhelming enemy tanks with massive damage output.

Build your team around this amazing effect by equipping Special skills that can be easily pre-charged with this effect!

Harmonized Skill buffs Mia and Alies

Summer Mia's harmonized skill grants her and all allies coming from Fire Emblem titles such as Radiant Dawn, Path of Radiance and Awakening +4 Atk/Spd. There are a lot of powerhouses from these titles such as Ike and Chrom so this can be a great skill depending on the circumstances.

The skill does not have any additional trigger requirements besides the one mentioned above. It is a combat buff, meaning, it can be easily stacked with other buffs and it does not make the target units susceptible to panics and chills. Lastly, it is refreshed at the start of every third turn. All of these quirks make this skill extremely valuable and adds to Summer Mia's value as a versatile unit.

Summer Mia Weaknesses

Weak to Cavalry Effective Weapons

Summer Mia takes 1.5x damage from cavalry-effective weapons like Ridersbane, and one blow from this type of weapon is sure to take her down. Make sure you know what weapons you are up against before hopping too far into the line of battle!

Summer Mia as a Source Hero

Value of Skills	★★★★★

Inheriting Swift Sparrow 3 or Spd/Def Snag 3

Summer Mia can be used to inherit the skills Swift Sparrow 3 or Spd/Def Snag 3. However, Summer Mia is a powerful and very versatile hero that can fit in many team compositions so we recommend against fodderring her off. Train her and make use of her abilities instead!
