3-6. Alliance Rallies

Coordinate with your Alliance members to take on powerful enemies that require teamwork to defeat. The rewards from these raids are shared amongst all participating members.

To attack Shutter Skulls strongholds, including bases, fortresses, gates, etc. you’ll need the support of your allies. These structures can only be attacked using rallies, so coordination is essential.

How to start a rally

1. Select an Objective: Begin by choosing your target objective. Once selected, tap on the objective and choose the "Rally" option.

2. Set the Preparation Time: Choose a preparation time that allows your teammates enough time to join your rally. Select the best option to ensure maximum participation. Tap "Rally" button again.

3. Form Your Troop: Next, create your troop by tapping the "Create New Troop" button. Select your strongest benders to ensure a powerful lineup.

4. Initiate the March: Finally, tap the "March" button to start the rally.

Your rally is now created! To monitor its progress, tap the trumpet icon located in the bottom-right corner of your screen. From the menu, you can see who has joined your troops and check the remaining time until the march begins.

3-6-1. Invasions

You'll also need your team to battle Corrupted Spirits during Invasions. These battles increase in difficulty with each successful challenge. Once your alliance achieves an Invasion objective, it will take about two days before you can challenge it again, and the next round will feature a higher difficulty level with fiercer battles. Preparation is key to progressing in this mode!

Invasion Start Conditions

To start an Invasion, your alliance must construct the Front Line.

The Front Line is an essential alliance building needed to combat Corrupted Spirits. Your alliance must occupy at least one stronghold to prepare for this. If your alliance hasn’t yet occupied a stronghold, work together with your members to strengthen your forces and control the territory.

How to Construct the Front Line
The Front Line can be built on a piece of land called a "Rift", located in territory conquered by your alliance. Some weaker lands may not have Rifts. The Front Line cannot be attacked by other alliances, but if the stronghold in that territory is captured and the territory is lost, the Front Line will be destroyed as well.

Preparing for an Invasion

Set a Specific Time: You must set a specific time in advance to gather your alliance members for the Invasion.

Invasion Reservation/Start: Invasions can be started either immediately or through a reservation. Both options can be executed by R4 or higher-ranking members, and the information will be communicated to all alliance members. When a reservation is made, alliance members can access the Invasion menu to begin the Invasion once the reserved time arrives.

Invasion Cancellation: Invasion reservations can be canceled by R4 or higher-ranking members, or for other specific reasons. If canceled, the information will be communicated to all alliance members. Canceling an Invasion reservation does not affect the cooldown period for the next challenge.

Invasion Battle Mechanics

Once the Invasion begins, the following rules apply:

Battle Duration
You have 30 minutes to conduct the battle once the Invasion starts. The powerful Corrupted Spirits will repeatedly repel your alliance’s forces, but no troops will die in this battle.

Rally Requirement
Corrupted Spirits can only be attacked through rallies organized by your alliance members. A rally can be started only when the preparation time runs out and the spirit icon appears in the bottom right corner of the screen. Once the rally is formed, the troops will engage the Corrupted Spirit in battle.

Corrupted Spirits’ Weaknesses
Each Corrupted Spirit has a specific weakness to certain bending techniques, which can help you counter them more efficiently:

Wan Shi Tong: Vulnerable to Waterbending.
Old Iron General: Vulnerable to Earthbending.
Hei Bai: Vulnerable to Firebending.
Dragon Eel: Vulnerable to Airbending.
Form a team effective against the Corrupted Spirit you’re facing in each round to maximize your success.

Invasion Rewards
There are two types of rewards in an Invasion:

Damage Rewards: Alliance members who participate in the Invasion and deal damage to the Corrupted Spirit will receive individual rewards based on their contribution.
Clearance Rewards: If the Corrupted Spirit is defeated at the stage your alliance is facing, all participating members will receive clear rewards, and your alliance will be able to challenge the next difficulty level in future Invasions.
