CRK Boss Rush guide - Best cookies for each stage of the event

With the addition of Shadow Milk Cookie and Candy Apple Cookie, there is a new event as well! This event is the Boss Rush event, where players have to figure out the best teams and elements to defeat the bosses in as few tries as possible. This is a complete Boss Rush event guide for CRK, so you will not have to waste any tries and win every single stage!
About the Boss Rush event in CRK
In the Boss Rush event, there are a total of 24 bosses you will have to challenge and win against for the ultimate prize. Each of the bosses comes with a different difficulty and weakness, and sometimes they even have multiple HP bars.Each of the bosses can be defeated within 1 to 2 tries usually, but if you use the wrong element to counter them, those 1 to 2 tries can turn into 4+ tries, which is a complete waste of tickets.
Important to know: Once you beat all 24 bosses, you can re-play the stages and aim for better timers!
CRK Boss Rush tips
When you first challenge the bosses you will see a few key elements that will help you win:- You should open the Supply Chest every single day to claim some free Suppression Spears, which are used to level up your Suppression Level.
- Level up your Suppression Level as much as humanly possible. That's passive stats that count for each of the stages.
- When you hit Enter in a boss fight, you should always tick the Practice button first so you can see what the boss is weak against (check the boss' debuffs), and plan a team accordingly.
- You can go with the teams offered in the Synergy Ideas if you have no idea which cookies to use.
- You can practice with the Rage status for bosses if you want to find out the element they are weakest to while having the second HP bar.
- Don't forget to always edit your team before heading into battle. When automatically deploying cookies from the Synergy Ideas, they will not have a Leader selected and you need to select it manually.
