Clash of Clans has launched the second challenge of its new season, Cosmic Curse Clash-O-Ween, called the ‘Fully Staffed Challenge.’ This guide will help you easily defeat the challenge base and earn all the rewards.
Introducing the Fully Staffed Challenge in Clash of Clans
Okay, so I’ve been checking out this base, and it’s really interesting! The defenses are all grouped together, but they don’t have walls protecting them, which could make it easier to break through. It looks like another challenge featuring a Controllable hero – this time it’s the Minion Prince, and he’s got this awesome new Meteor Staff! I’m excited to see how that changes things.

Since this is a Controllable Hero challenge, it’s key to protect your Hero until you’ve unlocked all your troops. The reward is essentially a trade: you’ll get a Hero Potion, 400 XP, and 25 Gems.
How to beat the Fully Staffed Challenge in Clash of Clans
The main goal of this challenge is to quickly clear out buildings. You’ll need to target and destroy defenses, then move on to the next one using your Minion Prince. A good place to start is on the left side of the base, where there’s a single Inferno Tower.
When you deploy the Minion Prince, tap it right away. This will quickly eliminate the Inferno Tower and also activate the Witches. Once the defenses are down, focus your attack on taking out the Witches.
Advance to unlock the Meteor Golems that appeared with the Cosmic Rock event. First, destroy the tower that makes enemies invisible, then take out the air defenses. After that, concentrate your attacks on the defending Minion Prince. Keep using the ‘click and destroy’ method to push forward, and you should unlock the Super Witch soon – eliminate them as well.
Next, focus on the single Inferno Tower. If you haven’t already, unlock the Bat, Heal spell, and LavaLoon troops. If the Inferno Tower is still attacking, take it out first. Then, target the Blacksmith buildings and be sure to remove any that you can, or you’ll lose them due to the time limit.
After that, make your way to the multi-gear tower. You might need to use your Minion Prince’s healing ability, but you should be able to manage. Then, let your Minion Prince take care of the Super Witch. Next, you’ll face the Single Inferno – it’s best to destroy it quickly without moving around too much, so it doesn’t target your Minion Prince.
You’ll also need to unlock a few more troops. The Monolith is now a significant threat, but you can handle it since your troops are already unlocked. Head to the top of the base to eliminate the remaining enemies, and you’ll be ready for a perfect three-star attack.
