During CRK’s Faerie Kingdom Battle event, you have to destroy a Contaminated Horde to earn Ally Skill EXP and Contribution points.
Cookie Run: Kingdom (CRK) players can now enjoy the Faerie Kingdom Battle to earn rich rewards.
During one of the preparation rounds, you have to defeat the contaminated horde with the help of Mercurial Knight Cookie.
For this round, your team’s attack speed will be increased by 10 percent at given intervals.
Furthermore, your Cookies will deal more or less damage depending on their attack speed rate.
To start the battle, you have to open the Faerie Kingdom Battle menu and select “Mercurial Knight Cookie”, who has to be part of your team to complete the battle.
Like with the normal gameplay, you are able to make changes to your team before the battle begins.
You can also adjust your team’s Toppings to enhance their capabilities, but you cannot alter Mercurial Knight Cookie’s Toppings, as they are fixed.
Once you have created your team, you can use one of your Preparation Round Tickets to begin the battle.
To make the battle easier, players can select the “Auto” button on the left side of the screen, which will enable your Cookies to fight automatically.
However players can still manually defeat the Contaminated Horde to complete the battle. When the battle is over, you will be notified of how many Ally Skill Experience Points you earned as well as your Contribution.

Which Cookies should you use?
Although you can use any Cookies to conquer the Contaminated Horde, this is not recommended as some Cookies will complete the battle quicker than others.
YouTuber, AEK CH suggests that you use Rebel, Linzer, Mint Choco and Creme Brulee with Mercurial Knight Cookie.
Alternatively, you can use Mango, Rebel, Linzer, Creme Brulee and Raisin with Mercurial Knight Cookie to defeat the Contaminated Horde.
That being said, you only have 1 minute to destroy the enemies to earn Ally Skill EXP and Contribution points.
However, your team may not be strong enough to vanquish all the enemies in 1 minute.

Toppings and Beascuits
To enhance the Cookies that you are going to use against the Contaminated Horde, you must equip them with the correct Toppings and Beascuits:
Cookie | Toppings | Beascuits |
Rebel |
|
|
Linzer |
|
|
Mint Choco |
|
|
Creme Brulee |

Can you fight the Contaminated Horde if you are a low level player?
In order to get access to the Faerie Kingdom Battle in CRK, you have to complete 2-10 in the normal story mode.
Once you have unlocked the event, you can enjoy its activities even if your Cookies are low level.
When you click on the Mercurial Knight Cookie, your Cookies’ level will automatically be increased to help you fight the Contaminated Horde.
