Legendary & Mythic Hero Battle: Ayra & Athos Strategy

Use a Player Phase team composition!

Using an offensive team composition is the ideal player phase strategy in order to prevent Legendary Ayra from stacking up Spd 【Great Talent】 from her Speedtaker 4.

If you have Emblem Sigurd in your barracks, the strategy is simple. Equip him with the Solid Ground 3 Sacred Seal, give him a visible Atk bonus, and eliminate Legendary Ayra on turn one. Retreat back to the safety of your team afterwards, either directly or via his built-in Canto after you attack the Axe Cavalier from below.

If you don't have Emblem Sigurd in your barracks, you will need to kite around Legendary Ayra and slowly whittle her down with ranged attacks. Bring ranged units that have true damage built into their kits and simply hit and run until Ayra is defeated.

As for the other units - the left side has a sturdy Lance Knight with Weaving Fighter and A/D Twin N Save. Bring a magic nuke with a Null Follow-Up effect to burst him down.

The enemy units will move on turn one even if you do not step into the danger area. Allow them to approach your units and pick them off one at a time, retreating to safety after each attack. Repeat this process until the map is cleared.

A Tanking Strategy is also possible!

It is also possible to form up into a ball and use Savior Tanks to enemy phase the entire map if you have a modern Near Save tank from recent releases.

However, ensure that this Near Save tank is carrying Armored Blaze and not the Shield Fighter + Pavise combo, as Legendary Ayra will ignore Defensive Specials and carve through your tank quickly.

Bring ample support for your Savior tanks and allow the enemies to approach and attack into your units.

By the time Legendary Ayra reaches your units, she will have stacked extra Spd 【Great Talent】 from her Speedtaker 4. Bring a ranged unit specifically to deal with her while your Near Save tank and healer withstand her attacks.

Legendary Ayra's lack of a Null Follow-Up effect forces her to rely on 【Potent Follow】 and is only able to attack twice instead of the expected three times if you use a Near Save tank that can prevent the enemy's follow-up attacks. If you can, use a tank with this effect. However, this is not necessary as long as your tank can survive Ayra's attacks.
