The Cosmic Calamity Challenge has arrived in Clash of Clans, bringing a fresh and fun twist to the game. It went live on October 4, 2025, and will be available until October 11, 2025. This time, the challenge isn’t about using a full army from the start it’s about strategy, timing, and smart movement.
In this special event, you’ll rely mainly on your Archer Queen, equipped with the Giant Arrow and Action Figure Equipment, to destroy the base and earn a three-star victory. Let’s break down how you can complete the challenge step-by-step and claim all the rewards.
What Makes the Cosmic Calamity Challenge Different
Unlike most Clash of Clans events, the Cosmic Calamity Challenge doesn’t start you off with a full army. You’ll need to move your Hero around the base, take down buildings, and free trapped troops to build your attack force.
To control your Hero, simply tap on the area or building you want her to target. The Archer Queen will walk toward it and attack anything nearby. It’s a simple mechanic but requires attention to timing and positioning to win.
Step-by-Step Guide to Three-Star the Challenge
Follow these steps carefully to clear the Cosmic Calamity base and earn all three stars:
- Start by deploying the Archer Queen in the allowed deployment zone.
- Tap the Gold Storage building on the right side to begin clearing that section.
- When the Queen gets close to the walls near the storage, tap the Builder Hut located in the top corner of the base and activate her ability.
- Next, target the Monolith nearby and destroy it.
- Then move to the single-target Inferno Tower next to the Monolith.
- Once you destroy it, you’ll free the Superbowlers trapped in nearby camps.
- Move down toward the bottom corner to take out another single-target Inferno Tower.
- After clearing it, unlock the Unicorn pet to heal your Queen.
- Finally, destroy the multi-target Inferno Tower on the right corner of the base to finish strong.
If done correctly, this sequence will help you easily secure three stars and complete the challenge with minimal effort.
Rewards for Completing the Cosmic Calamity Challenge
Once you three-star the challenge, you’ll earn the following in-game rewards:
- 400 Experience Points (Exp)
- 25 Gems
- 1 Resource Potion
The Gems can be used to buy anything from the shop, while the Resource Potion will boost your resource production for one hour, making it easier to upgrade buildings or train troops faster.
