Preparation Phase

(Monday @ 3 PM - Saturday 3 PM GMT)

During the Preparation Phase, the main goal is to prepare your base for the next Attack Phase, which starts on a Saturday.  Each Preparation Phase lasts 5 days.

Continue reading below for more detail on how to prepare your League Base.

League Invasions Base View During Preparation Phase

• While viewing your base during the Preparation Phase, you can prepare your base with any of the 3 activities:
  1. Facilities
  2. Outposts
  3. Donate to upgrade Base Supply

Facilities

There are 5 total Facilities that affect the following Hero Classes:

 

Tapping on a Facility opens the Facility Details Menu.

From here you can upgrade different aspects of this Facility and upgrade & choose the Active Buffs for the next Attack Phase.  For this example, we’ll use the Paranormal Research Facility

.

Facility Details Menu

 

Each Facility provides a bonus to the base Attack and Health for a specific Hero Class.  These bonuses are applied to all Heroes of the League, on both Offense and Defense.  For this example, the Paranormal Research Facility only provides its bonuses to Arcane Class Heroes.

There are 2 ways to improve a Facility:

1. Upgrade Facility Level
2. Edit Facility Buffs

Upgrade Facility Level

Within the Facility Details Menu, along the bottom middle of the menu is an Upgrade button.  This allows you to upgrade this specific Facility, so in this case the Paranormal Research Facility. Tapping on “Upgrade” brings up the Facility Upgrade menu.

 

Facility Upgrade Menu

 

From here, you can see information about this Facility such as its current Level & bonus values, as well as how they will improve when the new level is reached.

Note: New Active Buff Tiers are unlocked at specific Facility Levels, generally every 10 Facility Levels.

 

Upgrading a Facility requires Credits. Credits can be earned throughout the game or purchased directly from the Store.  You can choose the amount you wish to invest towards the upgrade with the Currency Slider.   To choose your investment, you can either drag the indicator on the slider to the left or right, or use the “+” and “-” buttons to increase or decrease the value by a set amount.  When you are satisfied with your choice, tap the Apply button to add your contribution.

The position of the indicator also indicates the upgrade progress towards the next level. This progress is a combination of all of your League Member’s contributions, not just your own.  In order for the Facility to upgrade to the next Level, the Currency Slider must be completely filled with the indicator all the way on the right side.  

Facility Level upgrades are permanent and do not reset after each League Invasion Season or Split.

The maximum Level for each Facility is Level 40.

 

Edit Facility Buffs

Within the Facility Details Menu, along the right side of the menu is the Facility Info section.  This shows the bonus values granted by the Facility’s Level and the list of Active Buffs.

Active Buffs provide passive bonuses during the Attack Phase to certain Hero Classes while attacking or defending.

 

You can tap on an Active Buff to see its details.

Facility Active Buff Info Popup

 

The Active Buffs section shows the current Active Buffs assigned to this Facility, along with the Buff Tier unlock states.  Each Facility can have a maximum of 4 Active Buffs based on the Facility’s Level.  If a Buff Tier is not yet available, it presents as locked along with its Level requirement.

Using the Paranormal Research Facility as an example, it is Level 8.  Therefore, It only has the first Buff Tier available, and the rest must be unlocked by upgrading the Facility.  Tier 2 becomes available at Level 11, Tier 3 at Level 21, and Tier 4 at Level 31.

 

Level 8 Paranormal Research Facility Active Buff assignment

 

Once a Buff Tier is unlocked, it presents as an unassigned icon (a “+”).  A League Officer can now assign an Active Buff to this slot.

For this example, the Paranormal Research Facility is Level 8, so it only has Tier 1 available.

 

Active Buff Menu

Tapping on either an unassigned Active Buff (a slot with a “+” icon) or the “ALL” button opens the Active Buffs sub-menu.  From here you can choose which Active Buffs to upgrade, and League Officers can choose which Active Buff is assigned to each Tier.

 

Each Outpost has 8 total Active Buffs available, grouped as pairs within Tiers that are unlocked by Facility Level.  League Leaders/Officers can select any combination of unlocked Buffs, including both within the same Tier.  Each Facility can have a max of 4 Active Buffs selected.  The additional Buffs are unlocked at Outpost Level 11, 21, 31.

There are horizontal indicators to show which Hero Classes are affected by each Buff Tier.

• Tiers 1 & 2 only give their bonuses to the Hero Class for this Facility.
• Tiers 3 & 4 give their bonuses to all Heroes.

For this example using the Paranormal Research Facility, Tier 1 & Tier 2 will only affect Arcane Heroes.

All Facility Buff upgrades are permanent and do not reset after each League Invasion Season or Split.

Buff upgrade levels are limited by its Outpost Level, on a 1 to 1 basis in terms of Tiers.

For example, an Outpost Level of 21 thru 30 allows for Tier 1 & 2 Buffs to upgrade between 1 to 10.  To upgrade Tier 3 Buffs, the Outpost must be at least Level 32.

The maximum Level for all Buffs is Level 10.

Facility Buff assignments can be changed anytime throughout the Preparation Phase, but once the Attack Phase starts and the base has been readied, all Active Buffs will be locked in and cannot be changed until the start of the next Split.

 

Outposts

Tapping on an Outpost opens the Outpost Details Menu.

From here you can assign Heroes to support and defend the Outpost, and upgrade & choose the Active Modifiers for the next Attack Phase.

 

 

Each Outpost is a defensive fortification that is attacked by opposing Leagues during the Attack Phase.  Defeating the Defensive Heroes in all 4 Outposts conquers the League Base.

There are 4 ways to improve a Outpost:

1. Assign Deck Heroes
2. Assign Defenders
3. Upgrade Outpost Level
4. Upgrade Active Modifier Levels

Attack Phase Notification

 

League Invasion Button Attack Phase Active

 

Your Invasion Base is now in the locked state, and none of your Buildings can be modified.  The Attack Phase is a series of League Battles.  The number of League Battles available for this Attack Phase are shown in the upper left corner underneath your League , along with how much time is remaining for the entire Attack Phase.  League Battles available are shown as a row of boxes, with filled in boxes available League Battles and empty boxes used League Battles.

League Base during Attack Phase

 

Attack Phase Status & Info

 

The lower right corner shows the status of the League Battle availability.  League Battles must be started by a League Leader/Officer.  If a Leader/Officer has not yet started a League Battle, this section shows that one is available but has not yet been started.  Starting a League Battle begins matchmaking to find an opposing League to fight.  When an opponent is found, this section changes to a “Fight” button that lets League Members fight the opposing League.  It also shows the time remaining for this League Battle inside the “Fight” button.

Leagues should coordinate with their Leader/Officers to start League Fights as soon as they become available.

 

Each time your League finds a League to attack, your entire League has 3 hours to try and defeat every single Outpost.  Each Member has a limited number of attempts per League Battle.  Attempts reset every League Battle.

 

League Battle Ready States

 

Once your League has a League to fight, tap on the “Fight” button to open the Pre-Battle Menu.  From here, you can choose an Outpost to battle.  This flow is very similar to the Pre-Battle Menu for Arenas.  Tap on the Up and Down arrows above and below the Defensive Team along the right side of the menu to choose which Outpost to attack.  Coordinate with your League to defeat the 3 Defenders in all 4 of the opposing League’s Outposts.

League Battle Pre-Battle Menu

 

Both teams have Modifiers for League Fights.  You can see these by tapping on the “Modifiers” Button.  These are a combination of the Outpost Modifiers and Facility Active Buffs of each League’s Bases.  Your League’s Modifiers are on the left side, and the opposing League’s Modifiers are on the right side.

Outpost Battle Modifiers

 

The teams you use for League Battles must meet the requirements for each Outpost.  Each Outpost has different requirements, which you can view by tapping on the [i] button in the bottom middle of the menu.

Outpost Team Requirements

 

You can edit your team with the “Edit Team” button in the lower left corner of the Pre-Battle Menu. This flow is very similar to the Team Select Menus for other game modes.  The difference here is that the Heroes you assigned into Outposts during the Preparation Phase are not available to use.  They will have a label on them to show you who was assigned and is now not available.  Also, the Outpost’s requirements are shown below your selected team, with a status check mark to show if your current team meets the requirements.

 

League Battle Team Select

 

When a League Battle is over, you are presented with a summary of how much damage you dealt, the status of the Defending Heroes, and the League Invasion Points you earned.  This is a factor of how much damage your team dealt.

 

 

When you return to the Pre-Fight Menu, you’ll see that some of your options are now Exhausted.  This means they can’t be used again for the rest of this League Battle.

• Heroes = They become usable again for the next League Battle.
• Artifacts = They have a cooldown, and can only be used again once the cooldown has ended. 

The Health values of the Outpost’s Defenders are shown with Health Meters on each Hero Portrait, including if they have been defeated. 

 

You can see the status of your Hero’s Artifacts with a status icon on each Hero.

• Green Icon: Available
• Red Icon: Not Available and in cooldown
• No Icon: Hero does not have an Artifact equipped

 

Artifact Availability Icons

 

Fighting is the way to earn Invasion Points for your League.  The more damage you deal, the more Invasion Points you contribute. Defeating Defenders earns even more points for your League, so participating in as many League Battles as possible is crucial to maximizing the amount of League Points your League can earn during the entire Attack Phase.  

Whether or not your League is able to defeat all Defenders during the League Battle’s 3 hour duration, it ends and a new League Battle can be started. If your League wins the League Battle early, your League can start another League Battle right away.

 

Battle Logs

The League Points earned from all League Members are added together to generate the final League Points for your League’s Leaderboard placement and Division promotion/demotion opportunities.  You can view your League’s standings with the Battle Logs Menu.  

Battle Logs let you view your League’s Progress in the entire League Invasion season.  The top section of the menu shows your League’s overall progress and status, including its promotion status.  There are buttons to switch the view below between the Battle Logs or the Leaderboard.

For Battle Logs, each Split has its own set, divided into Offensive and Defensive Point totals.  Along the bottom of the menu, you can use the arrow buttons to cycle between each League Fight that has taken place during this Split.

Battle Logs Offensive

 

The Offensive section lists the League Point totals earned from all Outposts of the base.  These are the combined points from all League Members based on the damage they have dealt.  Also shown is if your League defeated each Outpost during this League Fight.  Each Outpost will show as “Survived” or “Defeated”.

Battle Logs Defensive

 

The Defensive section lists the League Point totals earned from your Outposts while defending.  Also shown is if your Outposts were defeated during this League Fight.  Each Outpost will show as “Survived” or “Defeated”.

The League Points for each Outpost are based on whether they were defeated.  Defeated Outposts earn 0 Points, but the time it took to defeat them earns additional points, which are included in the “Total Points for this Invasion” display.

 

Note: The total number of Offensive and Defensive League Battles that can take place during each Attack Phase are different totals:

• Offensive Battles = the number of times your League Leader/Officers began a League Battle.
• Defensive Battles = the number of times your League was found as an opponent by opposing Leagues.

Summary

That’s all there is to it!

 

Each week is a new Split. Each League Invasion Season has 4 Splits. Each Split consists of a Preparation Phase active from Monday to Friday and an Attack Phase active from Saturday through Sunday.

You can learn more about the different League Invasion Seasons here.

Utilize the Preparation Phase to make your Base and Defenders stronger by Upgrading Heroes, Outposts, and Facilities. When the Attack Phase starts, participate as much as possible to earn the highest amounts of Invasion Points for your League.

At the end of a Split, Split Rewards are sent to your Inbox.  At the end of the Invasion Season, Final Split Rewards are sent based on your League’s placement in the Seasonal Leaderboards (coming soon). These Final Split Rewards include an Artifact Chest, a Hero Chest, and Consumables.  Based on your League’s Division, the chance for chests to drop Legendary Shards increases, and the highest Division Tier’s Hero Chest rewards guaranteed Legendary Shards!
