Best Cookie for Error Buster Season 2 Cookie Run Kingdom CRK Guide!

If you’re aiming for a top-tier ranking in Cookie Run: Kingdom’s (CRK) Error Busters Season 2, you’ve come to the right place! Achieving a top 1% finish in this mode requires strategy, timing, and the right team composition. In this guide, we’ll break down the key tips and cookies needed for a fast and effective 290-second clear. While this guide represents my current best run, remember that updates will follow as I refine the strategy for even better results.

Best Cookies for Error Busters Season 2

1. Stormbringer: The Key Cookie

Stormbringer is one of the best cookies for Error Busters Season 2. Her abilities can handle any enemy, making her a strong choice for any team. If you’re aiming for a solid clear, she should be your go-to. However, if you don’t have Stormbringer or prefer an alternative, Lemonade and Burning Spice can be used as replacements, though they might not perform as efficiently as Stormbringer.

Stormbringer is arguably the best choice for this event, as she can handle enemies effectively on her own. Her versatility makes her a strong choice for clearing enemies quickly, which is crucial for achieving that 290-second clear time. However, as mentioned, you can experiment with alternatives like Lemonade or Burning Spice if you find that Stormbringer isn’t performing well for your team setup.

2, Cookie Substitutes and Flexibility

While Stormbringer is the MVP, it’s always good to have backup cookies for different team compositions:

  • Lemonade Cookie: Good for supporting or additional damage.

  • Burning Spice Cookie: Another viable alternative, though not as powerful as Stormbringer.

Tips & Tricks for Achieving a 290-Second Clear in Error Buster

1. Focusing on Bug Fixes for Improved Performance

To enhance the speed and power of your team, it’s important to make sure your cookies are benefiting from the correct bug fixes. Bug fixes can optimize cookie performance by resolving issues that might otherwise slow down or hinder your progression.

  • Speed Bug Fixes: Some cookies may have performance issues that can affect their overall speed. Make sure to implement the appropriate bug fixes to ensure that your cookies are moving at their fastest. Faster movement means faster damage output and quicker completion of stages, both of which are crucial for achieving a low clear time.

  • Power Bug Fixes: Additionally, there may be bugs that affect the damage output of your cookies. Using the right bug fixes can enhance your cookies’ abilities, making them more powerful and allowing them to defeat enemies faster. The stronger your team, the quicker they can clear each stage, helping you maintain the pace needed for a 290-second clear.

2. Keep Focused on Speed and Efficiency

While dealing damage is important, the primary objective is to clear the level quickly. Efficiency is key, which is why your team should be able to handle enemies swiftly. Stormbringer’s ability to clear mobs and deal damage is unmatched, but remember to keep your team in top shape by upgrading your cookies and ensuring you’re using optimal gear.

3. Strategy for Handling Difficult Phases

Once you have the right cookies and bug fixes in place, it’s time to fine-tune your team composition. Your team should be balanced, with a good mix of cookies that provide both damage and utility. Cookies like Stormbringer and Lemonade excel in both areas, making them perfect for this challenge. Be sure to also include support cookies that can help with healing or additional buffs, but prioritize speed and damage above all else.

4. Experiment with Different Combinations

While Stormbringer is the most recommended cookie for this challenge, don’t be afraid to experiment with different combinations of cookies. Lemonade and Bur Spice are viable alternatives, and depending on your team’s synergy, you may find that one of these cookies works better for you. Testing different combinations of cookies can help you discover the perfect setup that maximizes speed and damage.


Achieving the Top 1% in Error Busters Season 2 is a challenging task, but with the right strategy and team, it’s absolutely doable. By using Stormbringer (or similar cookies), paying attention to sound cues, and refining your timing, you’ll be well on your way to hitting that 290-second mark. Keep experimenting, and you’ll eventually get the hang of it. Best of luck in your journey toward the Top 1%!
