Frontline Phalanx is an event in which summoners send their support to Heroes in other worlds struggling against the odds. Provides support to the four armies to repel the invaders!

Basics[ | ]

Guide Frontline Phalanx boost

Frontline Phalanx event consists exclusively into sending Icon Reinforce support forces to one of the four armies. Players can get score based on the number of Icon Reinforce support forces sent to a given army and the multiplier of that army at the end of the battle. Every battle lasts an hour. Any number of Icon Reinforce support forces can be sent to any of the armies at the same time, but once Icon Reinforce support forces have been deployed to an army, is not possible to sent them any more before the next battle.

Each army has a probability of winning and multiplier which lie between their minimals and maximals. Given the basic probability of an army, it is possible to calculate the second probabilitiy and both multipliers. The lowest probability is calculated as , while the multipliers and are calculated as and .

The actual probability of winning and multiplier depend on the total amount of support an army gather during a battle. The higher total number of Icon Reinforce support forces are send to an army, the higher will be the multiplier, but the lower will be the probability. The rate of support for the last 3 hours can be found when going to Support Intel → Total Support. A simplified formula for the winning probability is . The associated multiplier can be retrieved using the above formula for .

The score a player will obtains at the end of a battle depends on several factor. It is initially defined as:

Moreover:

  • In case of Defeat, is reinitialized at 1.
    This can be avoided by using a Guardian Shield Guardian Shield on that army.
  • A Victory may be transformed into a Triumph, adding an additional 2.0x multiplier.
    • Likely, a Defeat may be transformed into a Total Loss, adding a 0.5x multiplier.
  • Using a Guardian Shield Guardian Shield will also add an additional 1.2x multiplier.
  • The activation of Skjaldborg will results in the addition of another 1.2x multiplier.

A player can use a Guardian Shield Guardian Shield to secure its forces. Not only will this add a 1.2x multiplier to the player's score, it will also disable the reset of the army's multiplier in case of Defeat or Total Loss. Note that this does not neutralize the 0.5x multiplier in case of Total Loss. These effects apply only for the players using a Guardian Shield Guardian Shield, and will not change the output of the battle.
However, if enough players use a Guardian Shield Guardian Shield on the same army during the same battle, Skjaldborg will be activated. In that case, the army is guarantee to end the battle with a Victory or a Triumph, in addition to the 1.2x multuplier.

Strategy & Tips[ | ]

Since this game mode is nothing but gambles, there is no such things as a winning strategy. However, there are some tips which should be followed in order to score as high as possible.

  1. Do not use a Guardian Shield Guardian Shield on an army where Skjaldborg is already active. Even if this would add an additional 1.2x multiplier to the score, it is better to use it on a battle which would be lost.
    • The activation of Skjaldborg can be known by looking at the Shield icon on the army banner. There are 4 possibles states: fill at 1/4, 1/2, 3/4 and complete. If it is complete, that means Skjaldborg will be activated.
  2. Restrict the usage of a Guardian Shield Guardian Shield to an army with a very high multiplier, i.e. a final multiplier of 9.9x.
    • The army with the highest bonus / lowest probability is likely to have its basic multiplier increased by 1 or even more.
    • The other armies multiplier will typically increase by approximately 0.5.
    • Keep in mind that a Frontline Phalanx event is typically active 6-10 days. It may be tempting to use a Guardian Shield Guardian Shield on an army with a final 7.5x multiplier, but a better opportunity is bound to appeared later.
  3. Avoid sending every Icon Reinforce support forces to the same army. It is more profitable to send a few to every armies, securing a minimum of points, rather than all to the same, and risking a big loss.
    • However, if a Guardian Shield Guardian Shield is planned to be used, it is more interesting to send them all on the same army.
  4. The advices of the trio of the Order of Heroes follows a certain pattern.

Anna Commander Face Anger

Alfonse, Sharena...I would like to ask
your advice. Of course I'd like your
input too, 【Summoner】.

アルフォンス、シャロン。
それに【Summoner】
相談したいことがあるんだけど。

How can we help, Commander Anna?

何ですか? アンナ隊長。

Alfonse Prince of Askr Face FC
Alfonseアルフォンス
Anna Commander Face Anger
Annaアンナ

I've heard word that an incredibly
powerful foe appeared in another
world, and they seek our aid.

The threat is too great for the
Heroes of their world to face
on their own.

実はね、とある異界に
強大な敵が現れたらしいの。
救援の要請が来たわ。

その異界の英雄たちだけでは
とても太刀打ちができないそうよ。

Oh! They're in trouble, so they ask
for help from another world...

はぁー、なるほど。
ピンチなので異界のわたしたちに
助けてほしいと…

Sharena Princess of Askr Face FC
Sharenaシャロン

Just like we do!

要するに
わたしたちと同じですねっ!

Sharena Princess of Askr Face Smile
Sharenaシャロン
Alfonse Prince of Askr Face Normal2
Alfonseアルフォンス

You have a point there. We have
brought the Heroes helping us here
to join us from other worlds...

Now it's time for us to help them
in return!

そうとも言えるね。
異界の英雄たちには僕たちも
助けられている。

今度は僕たちが助ける番だ。

I'm glad to hear you support the idea.
However, the situation is a bit more
complicated than that...

そう言ってくれて助かるわ。
でも、ちょっと事情が複雑なのよね。

Anna Commander Face FC
Annaアンナ

Under the circumstances, we can't
all rush into battle.

Our ability to help is limited
to sending reinforcements.

So, we have to send support forces
out to the four Heroes who have
already engaged the enemy.

Our foe is a general with a vast army
under their command.

今回は私たちや
【Summoner】
直接乗り込むわけにはいかないのよ。

その異界で敵と戦っている
4人の英雄たちに援軍を送って、
彼らを援護する形になるわ。

敵は強大な敵将と
その敵将の率いる数多の兵。

Anna Commander Face Anger
Annaアンナ

We don't know the exact numbers,
just that they are an overwhelming
force to face.

正確な数は分からないけど
かなりの大軍らしいわ。

Anna Commander Face Pain2
Annaアンナ
Alfonse Prince of Askr Face Anger
Alfonseアルフォンス

Facing such numbers, will our
reinforcements be enough?

そんな大軍相手に
僕たちの送った援軍だけで
大丈夫なんですか?

That is another complication. The call
for aid is being heard by the Orders
of Heroes from many other worlds.

そこは心配ないわ。
この救援依頼は
様々な異界の特務機関へ送られているの。

Anna Commander Face FC
Annaアンナ

And the support forces they send
are rallying behind the four Heroes
on the ground there.

そうして派遣された援軍を
4人の英雄たちが率いて戦うのよ。

Anna Commander Face Smile
Annaアンナ
Sharena Princess of Askr Face FC
Sharenaシャロン

Even Orders of Heroes from other
worlds are joining in to help, then!
That's a comforting thought!

いろんな異界の特務機関
みんなで力を合わせるってことですねっ!
それなら心強いですっ!

The support forces being deployed
are outfitted with Guardian Shields,
which can be crucial defense.

The Guardian Shield can be used
for protection, but it can be used
only up to three times per battle.

Timing use of Guardian Shields will
be critical to success.

それに、派遣された援軍には
ここぞという場面で使える秘宝、
【守護者の大盾】が与えられるわ。

【守護者の大盾】は自身の身を守れるの。
でも1回の戦闘で3回しか使えないから
注意が必要よ。

Anna Commander Face FC
Annaアンナ

If many Guardian Shields are used
by the support forces at once...

更に、たくさんの
【守護者の大盾】が集まると…

Anna Commander Face Pain2
Annaアンナ

A power that will protect the
entire army will be unleashed—
the Skjaldborg shield wall!

自軍全体を守るほどの力が発揮される
【スキャルドボルグ】を
おこすことができるのよ!

Anna Commander Face Cool
Annaアンナ
Sharena Princess of Askr Face Smile
Sharenaシャロン

Wow! That sounds amazing! I want
to see it for myself!

わー、それはすごいですっ!
わたしも見てみたいですーーっ!!

The more support we send, the
deeper into the enemy's forces
our Heroes can cut.

But the more our forces extend
themselves, the greater the danger
of the enemy turning the tables.

We will have to consider our choices
carefully... So, in that case, it's in
your hands, 【Summoner】!

援軍が多いほど
英雄たちは敵陣の奥深くまで
切り込んで戦果を挙げることができるわ。

だけど、それは返り討ちにされる
危険も増えるってこと。

その辺をよく考える必要があるけど、
あなたこういうの得意よね?
【Summoner】

Anna Commander Face FC
Annaアンナ

We're counting on you!

じゃあ頼んだわよ!
