Infernal Reinforcements

Freyja: Lady of Nightmare and Triandra: Nightmare Strategy

Weaken Freyja With Savage Blow 3 and AoE Specials

This Reinhardt used by the team in clearing the map chipped Freyja's HP down with Savage Blow 3 and Blazing Thunder.

Freyja starts with her Special already active, so she could one-shot your unit if she is allowed to counterattack.

She can also counterattack regardless of range, so attacking her when she is full health with a ranged unit is also dangerous.

The best way to defeat her on this map is to attack her allies with skills that do AoE damage like Savage Blow 3 and a Special like Blazing Thunder.

This will bring her HP down enough that she could be brought down without any worries.

However, Freyja does get stronger when she is alone, which could make taking her out when she's alone very tough.

Try leaving one enemy unit with her and defeat her first. Or use units that have Dazzling Staff 3 or Flash+ so Freyja cannot counterattack.

Units That Prevent Counterattacks

Kempf

Bridal Lyn

Mikoto

Brave Camilla

Freyja is Weak to Cavalry-Effective and Beast-Effective Weapons

In addition to her status as a green beast, Freyja is considered a cavalry unit.

This means that weapons that are effective against beasts or cavalry will be able to take her down, though keep in mind that Freyja will be able to reduce damage from units with lower speed than her.

A good unit that can potentially take Freyja out in one turn is Brave Lysithea.

Units With Effective Weapons

Brave Lysithea

Picnic Flora

Young Marth

Hoshidan Summer Micaiah

Beware of Triandra's Refresher Skill

Triandra is the other boss and is a dancer.

She will inflict debuffs on your team when she uses Frightful Dream, which is troublesome to deal with, so aim to defeat her first before dealing with Freyja.

She also possess Iote’s Shield, which will render flier-effective weapons ineffective, so take care in picking your team.

Units That Can Easily Defeat Triandra

Igrene

Brave Lysithea

Fallen Julia

Bramimond

Use Units That Neutralize Debuffs

Units That Neutralize Debuffs
Fallen Ike	Idunn	Kris (F)	Legendary Chrom

There are several enemy units that could debuff your team, like Triandra's Frightful Dream, so using units that neutralize debuffs are very helpful.

Dealing With Reinforcements

Because the map contains several reinforcements, it's important to defeat them as soon as they spawn.

Using dancers or skills that grant another action like Galeforce, or skills that grant mobility like Armor March 3 could prove useful in defeating multiple enemy units at once.
