I still remember the first time I accidentally pressed R3 during my journey through Hollow Knight: Silksong. Hornet spun a quick loop of silk around her head, and then nothing. No damage numbers, no stagger, no obvious change in the world. I was confused. The controller options menu didn't list the input, and rebinding didn't explain it. As a player who likes to understand every button, I made it my mission to solve this mystery. After some experimentation and a look at the PC keyboard mapping, I learned that the move is called 'Challenge,' and it defaults to the V key on keyboard. In this guide, I'll share what I discovered about this elusive ability, how it works, and why it might be more useful than it first appears.

What Is Challenge?

Challenge is an input that causes Hornet to throw a quick moving string of silk around her head for just a short second. If you try this on an enemy, it won't cause damage. So what's going on? According to the PC keyboard button mapping, this move is called 'Challenge,' and it's the default move set to the V key. That gives us a name, but what does Challenge actually do? The answer is simple: it's used to aggro or activate enemies. In other words, it draws their attention to you.

Why Would You Challenge an Enemy?

At first, I asked myself the same question. Why would I want to draw attention to myself in a game where enemies already hit hard? But after using it in a few tricky situations, I found a couple of solid reasons.

• Isolating members of a crowd. Say you walk up on a group of multiple enemies, but they haven't seen you yet. Try to use Challenge from a distance to see if you can lure in the enemy closest to you and get it alone for easier enemy management. This is especially handy in areas like the Moss Grotto, where groups of critters can overwhelm you if you rush in.

• Getting an enemy out of your way while platforming. For example, say you need to jump onto a tiny platform, and some little enemy is standing on the same platform, blocking your safe landing. Challenge it to try to get it to move out of your landing space. You may need to think quickly to attack it if it's now coming towards you, but at least you have somewhere to jump! I used this trick in the Deep Docks to clear a narrow ledge before making a risky jump.

• Triggering dormant enemies. Some enemies might be idle or hidden until you get close. Challenge can activate them from a safe distance, letting you control when the fight starts.

A Quick Reference Table

My Personal Experience

I first discovered Challenge by accident while fumbling with the controller during a fight in the Marrow. I pressed R3, saw the silk swirl, and assumed it was a taunt with no purpose. Later, while stuck on a platforming section in Greymoor, I remembered the animation and tried it on a small enemy blocking my path. To my surprise, the enemy turned and walked toward me, leaving the platform clear. That moment changed how I approached crowded rooms. Now, I use Challenge regularly to split up packs and create breathing room.

The Name Suggests More

The name 'Challenge' also implies that there could be some more uses for the move yet to be discovered. For example, could we possibly 'Challenge' other characters in the world that would otherwise never turn hostile? If that's the case, I'll be sure to keep experimenting. As of 2026, the community has mostly settled on the aggro explanation, but Team Cherry has a habit of hiding deeper mechanics. I wouldn't be surprised if some secret interaction exists.

Final Thoughts

Hollow Knight: Silksong doesn't offer much in the way of training. Whether Team Cherry assumed you already know enough from the original game, they simply trust you to figure things out, or a couple of things have been forgotten, you're going to have to do some work on your own either way. Sometimes, that means learning mechanics and ideas on the fly. The good news is, you usually have enough context clues in things like the option menus and the world itself to piece together what everything does. Challenge is a perfect example: an undocumented input that turns out to be a useful tactical tool. So next time you see a group of enemies or a blocked platform, give R3 a press. You might just solve a problem you didn't know you had. 🎮🧵
