The Colosseum of Fools is an arena in Hollow Knight you can participate in to test your skills. It consists of trials that challenge you to fight waves of enemies. Here’s everything you need to know about the Colosseum.

    Getting to the Colosseum of Fools

    To reach the Colosseum for the first time, you’ll need to head to Kingdom’s Edge and ascend its western chasm all the way to the top. As you arrive at a darker cavern, continue making your way up until you spot an opening in the upper left ceiling.

    From here, make your way up and destroy the barrier on the left. The path here leads to an elevator shaft in the City of Tears. That will make your next trip from the nearest Stag Station to the Colosseum much shorter.

    Proceed to the right and you’ll arrive at the Colosseum.

    The Trials

    The Colosseum of Fools consists of three trials. You’ll need to pay a certain amount of Geo to unlock it. After you unlock a trial, you can then participate in it as many times as you want without a cost.

    When you first arrive at the Colosseum, you’ll only be able to unlock the first trial. The second will become available after you complete the first, and the third after you complete the second.

    Each trial will have you fight multiple waves of enemies. Certain waves are incorporated with a shift in the arena. This shift will either place spike pits, add floating platforms, or make the arena shorter or narrower.

    Trial of the Warrior

    The Knight attempting the Trial of the Warrior.

    The first and the easiest trial. You’ll need to pay 100 Geos to unlock it. If you win the trial, you’ll be rewarded with a Charm Notch and 1,000 Geos. You will need to undergo over 11 waves of enemies to complete this trial, and one more if you’ve rescued Zote the Mighty in Greenpath and in Deepnest.
