Quest

Go to the Cours de Fontaine and speak to Security and Surveillance Patrolwoman Turenne, standing at a small table on the left platform of the port. She will tell you about a new board game. It includes combat scenarios that the of the Special Patrol encounter during missions. Anjiani, the instructor of the Chamber of the Jardinage, does not believe that the Traveler will get past the third attack scenario.

The girls started a bet where Turenne puts up a limited supply of Captain Chevreuse's ammunition to prove that her partner has rather lost her form in solving combat problems. The adventurer will have to show his tactical skills and not let the patrolwoman lose the bet.

Reward for completing the task:

• ×10 pestilence;
• × 4 adventurer experience.

Formation of a battle formation

The initial scenario will teach you the basics of the game and practice attacking an area with the Hilichurl Fighter and Electro Shamachurl figures. The main enemy in this stage is the Cryo Hopper, which deals area damage with ice spikes and attacks when approached.

Please note that the tactics for completing stages may vary slightly depending on ping, internet connection quality, and device. All of this may affect the operation of hitboxes and damage dealt to allies and enemies.

Attack in three waves

In battle you will have to use two types of enemies, placing them in sequence.

1. Place Electro Shamachurls first, as they have long range and are less susceptible to Cryo Jumper attacks.
2. For a faster age, we recommend first placing the distant fighters on one defender, after which they will independently switch to the second. This way, more figures will survive.
3. Next, release 2 Hilichurl squads closer to the entrance to the area to deal with the forward base and the command center.

They showed the entire sequence of actions:

Bayonet strikes and shooting

In the second stage you will meet large Hydro slimes and Treasure thieves with the Pyro element. Slimes are ranged units and can deal damage from the other side of the barricades, just like Pyro Chemists. It is important to position the units correctly and break through the walls before they are killed by the defenders' attacks.

Use melee and ranged figures

In battle, you need to quickly deploy melee warriors after destroying obstacles.

1. Place 2 Hilichurl Grenadier units opposite the barricades, and save 1 unit for the end of the scenario. These units are best at destroying wooden structures. It is normal for figures to be killed in the process.
2. Place immediately after destroying the wall
3. Help your close combatants defeat the Hydro Slimes and send out the last group of Hilichurls to destroy the remaining obstacles and deal damage to enemies from long range.

Siege Strategies

The third scenario teaches you how to control flying figures. Their main advantage is that they are out of range of melee monsters. In battle, you need to follow the correct order of summoning troops in order to take the least damage from new opponents, Lavachurls with frost shell.

Attack vulnerable spots from the air

Use the Cryo Ghosts' distinctive attack feature to take out the large fighters defending the area.

1. Place 2 Cryo Ghosts and wait for them to destroy the first one.
2. Afterwards, release the Guardian of Ruins onto the battlefield, and together with the flying figures, he will kill the remaining opponents.
3. Deploy the last squads of fighters to destroy the control center and forward bases.

Science of Kinetic Energy

The fourth scenario unlocks Special Mechs with a priority on attacks on flying targets, which makes it a bit more difficult to quickly complete the stage. It is important to maintain a balance on the battlefield and deal damage from both the ground and the air.

Break through slow enemies

Use different types of allies and take into the characteristics of enemies, some of which have a fairly slow attack speed and movement speed.

• Place one Electro Cicine and one Decaying unit on the field.
• After killing the Cryo Jumper, send a squad of Hilichurl Fighters to help.
• When the warriors are almost done with Specmek, deploy another squad of Electro Cicyn. They will no longer be a threat and will help eliminate the remaining enemies.
• At the end of the scenario, send in the last of your fighters: the Hilichurls will quickly deal with the Hoppers, and the decaying Incarnation of Lava will make a significant contribution to the destruction of the control center and bases.

Commander in armor

In the fifth stage, you will learn about special restraining mechanisms. Figures caught in them become easy targets for ranged defenders. It is necessary to think through a strategy in advance and minimize attacks on vulnerable allies in order to the Commander in armor without losing a squad.

Use intelligence wisely

Eliminate enemy ranged and clear a safe path for infantry.

• Send Cryo Ghosts onto the battlefield from both sides of the barricades to destroy the large Hydro Slimes that deal damage to trapped units.
• Deploy two Hilichurl units after the ranged enemies are killed. Some of the troops will be trapped in a binding mechanism for a while, while the other units will go to destroy strategically important buildings. Once freed, the figures will attack the SpecMechs, and the rest will them later.

Through the trenches

The sixth scenario teaches you to think outside the box and use the enemy's defensive structures against him. An improved security system appears - a trap mechanism. In battle, it is important to use the properties of exploding objects to your advantage and be able to sacrifice part of the army for an advantage on the field.

Open up new avenues of attack

Make lethal devices an additional source of area damage to complete the Trenches stage.

• Place the Hilichurl Grenadiers one after the other on the right and
• Send in two Hydro Mimics separately to deal with the Pyro Chemists, who deal lethal damage to allies with a focus on destroying objects.

• At the end of the battle, on the right side, deploy a Hilichurl army with the aim of targeting the central buildings of the enemy territory. And place the second squad at the top of the field to destroy the Forward Base.

Sequence of actions in the video:

Big army

The seventh combat mission is focused on managing an increased number of figures, which forces you to think through your actions several steps ahead. It is more difficult to change tactics in a mass battle, and the relationship between the unique abilities of the troops is more clearly visible.

Focus on a clear strategy

Assess the fighters' qualities and distribute roles on the field to complete the Big Army:

• Use Ruin Guardians as tanks to allow weaker allies to attack.
• Call in two groups of Electro Shamachurls to destroy enemies from long range and clear the way for infantry.
• Complete the scenario by summoning Hilichurl fighters to destroy obstacles and enemy bases.

More fire, less harm

Stage 8 focuses on channeling powerful incoming damage to more resilient monsters. In battle, it is important to combine tanking and damage-dealing units to break through the defensive line.

Use melee warriors

Deploy your pieces in a specific order and avoid exposing units with less defense to attack.

• Place the Ruin Guard opposite the barricades to attract the defenders' attention and provide cover for weak troops.
• Send Electro Shamachurls and Hilichurl Grenadiers - the former will destroy the Pyro Chemist line, while the latter will clear the path of obstacles.
• When the first Ruin Guardian is almost killed, summon another one to ensure that the less resilient units are not left without a living shield.
• Deploy reinforcements to the surviving figures and wait for the sortie to be completed.

We recorded the sequence of actions:

Raindrops in the mountains

The ninth scenario is tied to taking into the range of the defensive skills. The difficulty in ing lies in the location of the Special Mek, which hits flying fighters and does not allow you to quickly eliminate defenders with area damage.

Strike from an unexpected direction

Before the battle begins, think in advance how to approach the Pyro shooter with melee figures. A competent start to the scenario will help you complete "Raindrops in the Mountains" in a fairly short time.

• Place two Cryo Ghosts in front of the Lavachurls so that they are not in Specmek's attack range. This will remove the strong opponents for infantry.

• After killing the Lavachurl, send the Decaying Avatar of Lava to break through the barricades.
• Once the obstacles are cleared, deploy the Hilichurl Fighters and target the Cryo Hopper. From there, the figures will move towards the Forward Base and the SpecMek.
• Once the Pyro Gunner is dead, place a Cryo Ghost on the left and two Electro Cicyn units on the Control Center side.

• To help the floating objects, call the last Hilichurl fighters and wait for the mission to end.

Like peeling an onion

The penultimate combat mission is a field surrounded by enemy traps. As you capture it, gradually weaken the enemy's lines of defense and pave the way to strategically important objects to complete "Like Peeling an Onion".

Destroy defensive fortifications

Use the advantage of hovering warriors to reduce damage to ground fighters.

• Place two Electro Cicyn squads opposite the Forward Bases and wait for them to destroy the Cryo Hoppers and trigger the explosive device.
• Next, release the Ruin Guard onto the field, followed by the Electro Shamachurls. The elite monster will act as a shield while the mages deal damage to the Pyro Chemists.
• When the figures are ambushed, call in the Hydro Mimic. It will help finish off the barricades and deal with the line of Treasure Snatchers at the base with a shockwave.
• After the obstacles are destroyed, send the last Shamachurls to the Pyro Chemists on the right side. Thanks to the Guardian of the Ruins, they will not take damage from the defenders and will then poison the buildings.
• Finally, deploy two Hydro Mimics and the remaining Electro Cycins to reduce the capture time.

Clearing the Morning Fog

The final scenario is particularly challenging and requires a quick and planned response in troop management. everything you have learned about the abilities of the figures and get to the enemy camp through the explosive field.

Advance swiftly

Organize your fighters to work together and launch a powerful attack from multiple fronts to complete "Dispelling the Morning Fog."

• Deploy one Cryo Ghost and Hilichurl Grenadiers by defeating the Pyro Chemist in the bottom right corner.
• After the flying figure attacks the slime, call the Decaying Lava Manifestation to the right and direct it to the Control Center. Due to its higher health, the monster will activate the explosive device and stay alive.
• Set Hydro Mimic's crosshair to Specmek and send another lava incarnation to the center beforehand.

• the Hilichurl Grenadiers at the bottom of the area by summoning a Cryo Wraith and Hydro Mimic to destroy the Forward Base and nearby enemies.

• After the second SpecMek is dead, send the last ghost. At the end, the Pyro Chemist will kill the mimics, and the shockwave will completely destroy the enemy camp.

Противостояние

In the cooperative mode, the course of events can be changed by well-thought-out tactics and knowledge of the abilities of your fighters. The victory will be won by the side that has achieved the highest result in the allotted time or has gained 100% progress.

Which unit to choose for the Attack Formation

To create an attack squad, it is worth thinking in advance about the tactics you will use to quickly capture enemy territory.

If we consider the warriors aimed at destroying buildings, then the Decaying Incarnation of Lava is slower than the Hilichurl Grenadier. It is more advantageous to take the latter for quick destruction of obstacles, but the Hilichurls need tank — Guard of the ruins.

• For ranged attacks Electro Shamachurls are suitable, they deal damage to any element on the battlefield.
• Air attack will be provided by Cryo ghosts or Electro Cicina. However, ghosts can freeze Hydro figures, so they will be more useful.

As a general build, use the above combo. It includes elements of and powerful damage to defenders.

Place the pieces in cooperative mode in the following order:

• Deploy a Ruin Guardian to act as a tank for weaker units.
• Next, deploy Hilichurl Grenadiers and Electro Shamachurls. Some will destroy obstacles while others will deal constant damage to the defenders.

• Summon Cryo Ghosts after killing Specmeks, otherwise they will die quickly.

that these are basic tips that are suitable for the beginning of the capture. In other cases, focus on the arrangement of the enemy pieces.

In the video, check out the sequence of steps and teamwork of the selected fighters:

How to build a defense in the Defense Structure

Deployment of the defensive formation limited to a certain number of figures. It is important to identify the most optimal warriors and think through possible options for attacking the territory:

• Place at least one SpecMek to repel air attacks, preferably away from the edges so the opponent can't get to them quickly.
• Place elemental fighters with area damage at the edges of the area to attack approaching enemies.
• Place the binding mechanisms close to ranged warriors so that the monsters that get hit cannot avoid the blow.

• Use explosives in unpredictable places, but do not place them near bases - the Hydro Mimic wave will affect important objects.
• Fortify the control center with Lavachurls, they will deal with the Ruin Guardians and kill the small figures with one blow.
• Place the main base in the center of the defenders' cluster. Destroying the control center adds 50% territory capture.
• It is best to place forward objects at different points so that the opponent spends more time on the way to another point and destroying obstacles.

Check the formed defense squads with the help of defense modulation, so it will be possible to adjust the location of the warriors.
