=Conquest= In this event, the event story will progress by advancing the Conquest mode. Conquest is a base-control event in which the goal is to steal the tiles in the event area before occupying the entire area.
 * Like the previous Conquest mode event, the OOPArts and BPs drop rate is incredibly high. Try to farm as much as you can.
 * You should try to rush to Area 3 or 4 as soon as possible, as those areas have the highest efficiency for event currency drops.
 * If you want to maximize your Credits from Settlement, claim all of the tiles in Area 4, then 3, 2, and 1. After that, upgrade the Base Tile to Level 3 for Area 4, then 3, 2, and 1.
 * You can get by upgrading the Base Tile to Level 3.
 * There are a total of 29 Base Tile in this event, upgrading all of them to max will give players a total of.
 * Upgrading all base tiles to Level 3 will cost a total of, , and
 * If you have occupied all of the General Tiles and Base Tiles and upgraded all the Base Tiles to Level 3, you can earn 1,485,000 per Settlement gauge.

General Mechanics
There are 3 types of tiles in the Conquest battle area:
 * General Tile: Occupying the tile requires AP; no battle.
 * Battle Tile: Requires AP to battle and occupy the tile. Can not be analyzed.
 * Base Tile: Requires AP to battle and occupy the tile. Can be analyzed for rewards.

Once the Base Tile is occupied, players can Analyze the Tile by spending AP to obtain Multidimensional Computation Circuit, Dimensional Engine Parts, and Space Chocolate Burger. In order to Occupy and Analyze, players are required to assign teams for Battle and Analyze. Players can obtain bonus effects such as Battle Buffs and Reward Bonuses by assigning students to the specified schools.

There are 3 additional system beside Occupy and Analyze.
 * Settlement: is a function where players can earn credits as a reward when the AP gauge (500) is maxed out. The amount of credits that can be earned increases as players occupy more tiles and upgrade up their base tile.
 * Supply Box: A supply box is hidden in each area, and finding it will reward players with Pyroxene.
 * Erosion: Refer to Erosion for more details.

Battle Mechanics

 * Occupying General Tile costs.
 * Occupying Battle Tile costs.
 * Occupying Base Tile costs.
 * AP used to initiate a battle will be refunded if a player is defeated or gives up in a battle to occupy a Battle Tile or Base Tile.
 * The battle must be cleared with 3★ in order to Analyze on the Base Tile. If you clear the battle in 1★ or 2★, you can occupy the adjacent tiles but will not be able to analyze on the occupied Base Tile.
 * You must defeat the mob with the same faction number as the Boss enemy before you can challenge them.

Analyze Mechanics

 * Assign students to a base tile to get drop bonuses for the event currency drop when analyzing the base.
 * Players can borrow Club & Friend students to assist in analyzing the Base Tile. There are no rental fees.
 * Players can use the same students assigned to the analyzing team in combat team, and vice versa.
 * AP cost to analyze varies depending on the area, so please refer to in-game for more information.

Other

 * Spending AP outside of Conquest mode will not increase the Settlement gauge.
 * Base Tile can be upgraded up to Level 3. Each upgrade cost is different in each area, and certain tiles will use different event currencies. Refer to in-game for details.
 * Some Base Tiles contain significantly fewer analyze rewards, but the upgrade costs are also lower at 45 Event Currency for Level 2 and 3.
 * The Credits amount for Settlement rewards will increase by 50% at Level 2, and 100% at Level 3. Eligma will also be rewarded whenever the base tile level up.
 * Reward for Supply Box, Settlement, and Event Mission can only be received during the Event period.

Erosion
Erosion is a new mechanic added to this event's conquest mode. There are two types of erosion: small-scale erosion and large-scale erosion.
 * Small-scale erosion will erode 3 random base tiles. Reset at 4:00AM (JST) every day.
 * Large-scale erosion will occur once the condition are met. A warning screen will flash onto the screen when the large-scale erosion occurs.

Erosion Mechanics

 * From the 2nd day, the occupied tiles may be eroded and stolen by the enemy.
 * When a tile is eroded, a Penalty will be incurred that prevents you from Analyzing the eroded base and reduces the credit amount when collecting Settlement rewards. Make sure to remove the erode tiles before collecting the settlement rewards!
 * In order to remove the penalty, you must perform a removal operation on the eroded tiles and win the battle.
 * Removing the erosion will earn you Credits, Enhancement Materials, and Pyroxene.
 * Removal operations can be performed using either the Analyze team or the Combat team.
 * Analyze Team does not requires AP to remove the erosion, but you will not be able to change the team set before the erosion. If the team has an "assist" unit, a separate rental fee will be incurred.
 * Combat Team requires AP to remove the erosion, but you can freely choose their team members. The same students from the analyze team can be used in the combat team.

Large-Scale Erosion

 * Before large-scale erosion can occur, a certain amount of AP must be spent to meet the Notice Condition.
 * A notice will then be displayed the next day (reset time) at the main event screen that indicates the Erosion Condition.
 * Large-scale erosion can occur 3 times. Only one large-scale erosion can happen at a time.
 * Although the small-scale erosion only starts on the 2nd day, the notice condition for large-scale erosion can be met as early as the 1st day, meaning the First Erosion can occur on the 4th day, Second Erosion on the 7th day, and the Third Erosion on the 10th day.

Condition

 * First Large-Scale Erosion - Area 2
 * Notice Condition: Spend a total of 3,000 or more AP.
 * Erosion Condition: Spend a total of 4,000 or more AP and wait 48 hours.
 * Second Large-Scale Erosion - Area 3
 * Notice Condition: Spend a total of 6,000 or more AP.
 * Erosion Condition: Spend a total of 7,000 or more AP and wait 48 hours.
 * Second Large-Scale Erosion - Area 4
 * Notice Condition: Spend 9,000 or more AP.
 * Erosion Condition: Spend a total of 10,000 or more AP and wait 48 hours.

=Mission Details & Rewards=

Analyze Reward
Notes: On the JP server, there was a notation error where the Analyze Reward Bonuses had been applied to OOPArts as well, even though that was not intended. After consulting with the staff, they decided to turn the notation error into a feature where, if the OOPArts drop, you will also receive an additional one as indicated.

In this base control type event, players will need to organize teams based on specific schools rather than characters, unlike in other event, making it easier to get the max bonus without requiring specific characters. The Maximum Reward Bonus in each Base Tile is 120%.

Due to the tile-based map, it is impossible to pinpoint the tile's position. As such, there will only be the analyze reward in each Area. For enemy details, we recommend you to check out the event page at Schale.gg.

Bonus Effect:
 * Battle Team Damage Buff = 2 / 4 / 6 Unit — 50% / 100% / 150%
 * Analyze Reward Bonuses = 2 / 4 / 6 Unit — 40% / 80% / 120%
