Mamori

Preferred IV: +ATK or +RES / -SPD

• Increasing either Attack or Resistance is ideal for maximizing Mamori’s survivability in a mode like Aether Raids.

Weapon: Mirage Axe

• Mamori’s unique Mirage Axe can be considered a vastly improved version of Legendary Hector’s Thunder Armads, which is already a potent weapon on its own. With the relatively simple requirement of having an ally within two spaces, Mamori can massively improve her own survivability thanks to the boost to her defenses and follow-up negation.

Assist: Swap / Pivot

Special: Noontime / Sol / Aether

• Noontime grants Mamori a good amount of sustain, which can greatly enhance her survivability. She can easily activate it after every enemy attack via Special Fighter.

• If Special Fighter is unavailable, then using Sol or Aether with Vengeful Fighter is a decent alternative.

Passive A: Distant Counter

• Distant Counter is vitally important to allow Mamori to tackle ranged threats during Enemy Phase, as her Player Phase performance is very poor due to her low Speed.

Passive B: Special Fighter / Vengeful Fighter

• Special Fighter is a key component of this build, as the accelerated Special charge gain allows Mamori to repeatedly activate Noontime, greatly enhancing her survivability. Preventing enemies from charging their Specials can also be helpful, but is generally not quite as useful in Aether Raids since many enemies will have their Specials already charged via skills like Infantry Pulse.

• If Special Fighter is unavailable, then Mamori’s base Vengeful Fighter can work. Note that while Mamori has a lot of protection from getting doubled thanks to her Mirage Axe, enemies with skills that can bypass this (like infantry with Null Follow-Up) can easily double her due to her poor Speed.

Passive C: Pulse Smoke / Atk Smoke / Armor March

• Pulse Smoke is an incredibly powerful skill as it can single-handedly shut down Infantry Pulse-based defense teams in Aether Raids.

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

• Finally, Armor March is very useful for helping Mamori overcome her poor armor mobility. However, this carries a heavy opportunity cost of losing access to either Pulse Smoke or Atk Smoke, and is best left to a support unit if desired.

Sacred Seal: Quick Riposte / Mirror Stance / Fierce Stance

• Quick Riposte is important for this build, as Mamori doesn’t really have the raw damage output to KO most of her enemies in a single hit. This is unnecessary if utilizing her base Vengeful Fighter.

• Mirror Stance and Fierce Stance are both good options if using Vengeful Fighter or stacking Attack on Mamori to try to KO her enemies in one hit.

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

• While +ATK is generally ideal for a mixed phase setup, Mamori’s defenses are so immense that increasing her Defense or Resistance can allow her to take almost no damage from her enemies.

Weapon: Mirage Axe

• Mamori’s unique Mirage Axe can be considered a vastly improved version of Legendary Hector’s Thunder Armads, which is already a potent weapon on its own. With the relatively simple requirement of having an ally within two spaces, Mamori can massively improve her own survivability thanks to the boost to her defenses and follow-up negation.

• Note that the follow-up negation can hurt Mamori’s Enemy Phase damage output as not getting doubled makes it difficult for her to charge Bonfire.

Assist: Swap / Pivot

Special: Bonfire

• Mamori’s Defense is far higher than her Resistance, making Bonfire the clear choice for her Special.

Passive A: Distant Counter / Fort. Def/Res 3

• Distant Counter is important to allow Mamori to counterattack against ranged foes during Enemy Phase, but Fort. Def/Res 3 can allow her to be a massive wall on both phases.

Passive B: Bold Fighter

• Bold Fighter is the key that allows Mamori to consider attacking enemies on Player Phase, as her poor Speed otherwise prevents her from doing so effectively.

Passive C: Armor March / Flexible

• Armor March is extremely useful for any armor units that are trying to attack on Player Phase, and Mamori is no exception. 

Sacred Seal: Quick Riposte

• The Quick Riposte Seal, when combined with Bold Fighter, allows Mamori to double her enemy regardless of phase. However, Mirage Axe’s follow-up negation can potentially mess with Mamori’s damage output during Enemy Phase as preventing enemies from doubling her will make it more difficult for her to charge Bonfire.
