Aether Raids

Aether Raids Screen

Aether Raids is a game mode which debuted on 2018-11-09T07:00:00Z. The goal is to create, invade, and defend keeps.

Basics

The offense and the defense maps combine to create the battlefield.

Every battle consists of an offense map, and a defense map, which combine together to make the battlefield. The attacker controls the offense map while the defender controls the defense map. If the defender is defeated within seven turns, the attacker wins. If the attacker surrenders, it will count as defeat. Players gain or lose Lift based on these results, climbing to higher tiers and provided with more rewards if the player acquires enough Lift.

Aether

Aether Raids requires Aether to participate in battles. At the start of the season, a player's Aether starts with the capacity based on the level of their  Aether Amphorae. It is replenished by a fixed amount once a day, based on the level of the  Aether Fountain.

The amount of Aether it costs to start a battle is calculated as follows, capping out at 50 Aether maximum:

$\min \lbrace 9 + \lceil\mbox{Lift} / 200\rceil, 50 \rbrace$

The amount of Aether restored from destroying foe's resources during a battle is calculated as follows, capping out at 10 Aether maximum:

$\lfloor \min \lbrace 2 + \lfloor \mbox{Lift} / 1000 \rfloor, 10 \rbrace \times 0.5 \times \mbox{NumberOfResourcesDestroyed} \rfloor$.

Lift

A player's Aether Raids tier is based on Lift. When a new season begins, every player between Tier 12 and Tier 21 will start the season with an amount of Lift based on their Tier. Lift is gained by performing a successful raid. A completely successful attack, where no units are lost on the attacking side, yields the Maximum Lift amount, which is displayed when forming a raiding party. During the season, other players can attack, and lift is lost if the defensive team fails. Lift can only be lost once per 20 hour period. The Defense Lift Loss is the largest amount of Lift that can be lost given the makeup of the defensive team. On the Edit Defensive Team menu, the Defense Lift Loss is shown.

Attacking

When entering a battle, the formula for potential Lift Gain for a raiding party is:

$100 + (\#\mbox{Mythics} \times \#\mbox{Blessed} \times 10) + \#\mbox{Merges} + \mbox{BonusUnit?}$

#Mythics	Number of Offense Mythic Heroes in the correct season, offense attributes being Light and Astra. (Ex. Eir: Merciful Death during Light Season)
#Blessed	Number of Heroes blessed with the same attribute as the Mythic Hero (Ex. Light Blessed Alfonse: Prince of Askr). In addition, Legendary Heroes in the correct season are also treated as being appropriately blessed (Ex. Fjorm: Princess of Ice during Water season)
#Merges	The number of merges on each Offense Mythic Hero in the correct season. Merges on blessed units do not count.
BonusUnit?	20 if there is one or more bonus units for the current season, 0 otherwise. Only one bonus unit is counted.

If a Mythic bonus unit is not deployed in the offense team, for every unit lost during a successful attack, the total Lift gained will be decreased by 20. If a Mythic bonus unit is used, the total Lift gained will not be decreased if one unit is lost, and will be decreased for every unit lost after the first one.

Below is an example calculation during the following Season with  Fjorm: Princess of Ice and  Eir: Merciful Death as a bonus unit:

Offense Team	Potential Lift Gain
	100+0+0+20 = 120 Lift
	100+(1*1*10)+0+0 = 110 Lift
	100+(2*3*10)+0+20 = 180 Lift

The highest possible lift gained is 210 Lift requiring 3 Mythic units, all fully merged, with 2 other blessed units, and one of those 5 units being a bonus unit.

Auto-Dispatch

Auto-Dispatch is an alternative to Battle where the a player's raiding team attacks a randomised enemy defense team through auto-battle without player input. It can be used up to 3 times per season. When an auto-dispatched is called, both the Battle and Auto-Dispatch option will be unavailable for next 20 hours, unless the player chooses to cancel the current auto-dispatch. Cancelling will forfeit all Aether used to auto-dispatch and will not increase a players lift. After 20 hours, when the raiding party has returned, a replay of the player's raiding party auto-battling against the randomly generated defense will be shown. Other differences between the Battle and Auto-dispatch options include:

• Players only receive 75% of the total possible Lift upon victory.
•  Aether Amphorae and  Aether Fountain buildings are not placed on the defense team, meaning the player can not recover any lift from Auto-Dispatch.
• The raiding party cannot use an  Escape Ladder (O) if the auto-dispatch was a failure.
• The raiding party cannot use Movement Assists, but the defense team can.
• The raiding party cannot receive and EXP, SP, or HM from battling.
• Winning an auto-dispatch will not count as a completion of any mission, including "AR: Attack Successfully" missions. However, it will count towards the Aether Raids daily reward.

Defending

When defending, the most lift that can be lost in a 20 hour period is:

$-100 + (\min \lbrace \#\mbox{Mythics}, 2 \rbrace \times \#\mbox{Blessed} \times 5) + \min \lbrace \#\mbox{Merges}, 20 \rbrace + BonusDefenseMythic?$

#Mythics	Number of Defense Mythic Heroes in the correct season, defense being Anima and Dark. (Ex. Duma: God of Strength during Anima Season)
#Blessed	Number of Heroes blessed with the same attribute as the Mythic Hero (Ex. Anima Blessed Alfonse: Prince of Askr). In addition, Legendary Heroes in the correct season are also treated as being appropriately blessed (Ex. Fjorm: Princess of Ice during Water season)
#Merges	The number of merges on each Defense Mythic Hero in the correct season. Merges on blessed units do no count.
BonusDefenseMythic	20 if a bonus defense Mythic is deployed, 0 otherwise.

For every hero defeated during a defense, the player loses 20 less lift. If the defense successfully defends against an attack, no lift is lost.

Example calculation during the following Season with  Yune: Chaos Goddess as a bonus unit and  Sothis: Girl on the Throne is not a bonus unit:

Defense Team	Max Lift Lost
	(-100)+0+0 = -100 Lift
	(-100)+(1*1*5)+0 = -95 Lift
	(-100)+(1*1*5)+0+20 = -75 Lift
	(-100)+(2*4*5)+0+20 = -40 Lift

The lowest possible Lift Lost for defeat is -20 Lift Loss requiring 2 defense Mythic units (at least 1 is a bonus unit), all fully merged, with 4 other blessed units.

After a players defense team has been fought, they are given "Lift Loss Immunity" for the next 20 hours. This means if another player fights the same defense team within 20 hours, even if the defense team has failed, no Lift will be loss. Also, if the Lift a player has is 4000 or lower no Lift will be loss.

Defense Results

Explanation of elements on the Defense results screen.

Replays

Each season, players can watch how other players attacked their defense keep by tapping the Replay button for battle results listed on the Defense Results screen. This lets players watch the battle as it happened, as well as pause after every action. Each replay also notes how many foes was defeated, if the defense succeeded or failed, and how much lift was lost. All replays are erased once the season ends.

Lift Loss Control

After a players defense keep has been attacked by another player, whether the defense was a Success or a Failure, the defense keep becomes immune to lift loss for the next 20 hours. This is stated by the words "Lift Loss Control Active", followed by Lift being displayed as -0.

Rematches

Players can rematch those that have defeated their defenses one time. This acts as a regular battle and will consume the regular amount of Aether and has the same Lift gain. If the same opponent appears on the defenses list multiple times, they can only be challenged to a rematch once. For defense results that are a result of a rematch, the text "Your foe won the rematch!" will be displayed and the player listed cannot be rematched. The hero displayed to the left of the character is the hero on the first slot of the defense team when they are rematched, not that accounts first hero.

Story

English・Japanese

Annaアンナ	If I wasn't looking at it with my own eyes, I wouldn't believe it... And even now, I'm not sure I do.		…こうして目のあたりにしても、 まだ信じられないわね。 ここが…
It's just as it seems, Commander... This is the Aether Keep left behind by Líf, first king of Askr.		はい。 アスク王国初代王リーヴが 遺したとされる【飛空城】…		Alfonseアルフォンス
Sharenaシャロン	It's just as mother used to tell us when we were little. A castle that flies as freely as a bird... Seeing it is like seeing a dream!		自由にお空を飛ぶ城ですよね！ わたし、小さい頃にお母様から聞きました。 本当にあるなんて夢みたいです！
You're right, Sharena. It's just as mother said. I was certain those were mere fairy tales... Never did I imagine we would find it lying dormant all the way out here.		そうだね。 僕もてっきりお伽話だと思っていたよ。 まさかこんな辺境に眠っていたとは…		Alfonseアルフォンス
Annaアンナ	I can't help but wonder about the source who gave us the information that led us here... Just who could it have been?		それにしても、私たちでさえ知らなかった 【飛空城】の情報を送りつけてくるなんて… この謎の情報提供者…何者なのかしら？
Hmm...		…………		Alfonseアルフォンス
Sharenaシャロン	Alfonse! Commander Anna! Over here—you can see the whole thing!		お兄様ー、アンナ隊長ー！ 来てください！ こっちから全体が見渡せますよー！
Sharenaシャロン	It's been untouched for so long, it's practically in ruins. What do you think it was used for?		長い間ほっとかれてたから、 ずいぶん荒れ果ててますね～。 いったい何に使われてたんでしょう？
Battling in the heavens.		『天上との戦い』…		Alfonseアルフォンス
Sharenaシャロン	Huh?		え…？
A fire appears to have consumed much of the castle's library, but a trace of literature remained. It seems that the ancient Askrans used to travel the skies and do battle with Aether Keeps in other realms. The ultimate goal was to soar ever higher into the sky. It was a battle for power over the heavens.		城内の文献は、 燃やされた形跡があって、 これしか残っていないけれど… 古代の アスク王国は、 この城で数々の異界へ渡り、 異界の【飛空城】と戦ったらしい… その最終目的は 、遥かなる天の高み… 『天上』と称される勢力との 戦争だったことが伺える…		Alfonseアルフォンス
Sharenaシャロン	Amazing! They waged battle so high up?		天上… 空の上の誰かと 戦ってたんですか？
That's right. It's also said they employed special weaponry, both offensive as well as defensive.		うん。その戦争のために、 【飛空城】にはさまざまな 攻城兵器、防城兵器があったそうだよ。		Alfonseアルフォンス
Sharenaシャロン	Weapons on a castle? That sounds incredible! Do you think there are any still lying around?		攻城兵器！？ なんだかすごそうです！ 今もここにあるんでしょうか？
Good question, Sharena. I'm sure any we can salvage will come in handy later. Let's give this place a proper look right away.		今後の戦力になるかもしれないわね。 さっそくこの【飛空城】を 徹底的に調べてみましょう！		Annaアンナ

Trivia

• During the tutorial battle of the English version, the enemy is named "Otherworldly Order", which would be impossible for a regular player to have as a nickname because of the 12 character limit.

• Prior to Version 3.2, the amount of Aether it costs to start a battle was $9 + \lceil \mbox{Lift} / 100\rceil$., the amount of Aether restored from destroying foe's resources during a battle is calculated by $\lfloor (10 + \lfloor \mbox{Lift} / 100 \rfloor) \times 0.1 \times \mbox{NumberOfResourcesDestroyed} \rfloor$.
