If you’ve spent hours wandering the misty forest edges in Infinity Nikki and stumbled across a blocked stone entrance you can’t get past, you’re probably wondering how to open the gloomy cavern infinity nikki. This hidden area holds rare crafting materials, exclusive outfit pieces, and a cute side quest that most casual players never find, so it’s well worth the effort to unlock. I spent three afternoons testing different methods to get through the door before I figured out the exact sequence of steps you need to follow, no fancy rare items required.
Prerequisites You Need Before You Can Open the Gloomy Cavern in Infinity Nikki
You don’t need to be at a super high player level to unlock this area, but there are a few small boxes you have to tick first. I skipped these at first and spent 40 minutes running in circles trying to trigger the unlock, so don’t make the same mistake I did.
First, you need to have completed the Misty Forest Main Story Quest 12: The Disappearing Fireflies. This quest unlocks the ability to interact with the glowing crystal markers scattered around the forest edge, which are key to opening the cavern door. You also need to have at least 3 Glowmoss Clumps in your inventory – you can pick these up from under trees in the southern part of the Misty Forest any time of day. Finally, you need to visit the area between 8PM and 3AM in-game time, because the cavern door only responds to light when the sky is dark enough.
If you haven’t finished the main story quest yet, you can still collect Glowmoss Clumps ahead of time so you’re ready to unlock the cavern as soon as you hit that milestone. The clumps don’t expire, so you can hold onto them for as long as you need.
Step-by-Step Process to Unlock the Gloomy Cavern Door
Once you’ve checked all the prerequisites, the actual unlock process only takes 5 to 10 minutes if you follow the steps in order. I’ve tested this sequence on three different accounts, so it works for both free-to-play and paid players with no differences.
- Fast travel to the Misty Forest South Entrance waypoint, then head northwest until you see the large stone cavern door embedded in the cliffside. Don’t interact with it yet, even if you get a prompt.
- Look for three small glowing blue crystal pedestals within 50 feet of the door. Place one Glowmoss Clump on each pedestal, and wait for the blue light to turn soft gold.
- Once all three pedestals are glowing gold, walk up to the cavern door and play the Forest Lullaby emote you unlocked during the Disappearing Fireflies quest. The door will rattle for a few seconds before sliding open.
If the door doesn’t open after you do the emote, double check that you’re there during the correct in-game time, and that you didn’t miss any pedestals. I once missed a pedestal hidden behind a thick bush on the left side of the door, so take a second to sweep the area carefully if you run into issues. Once you get the door open, you can come back any time you want after that, you don’t have to redo the unlock process ever again.
What to Expect Inside the Gloomy Cavern Once It’s Open
Once you step inside the cavern, you’ll notice the light is dim, so I recommend equipping the Glow Lantern accessory if you have it, to make it easier to spot collectibles. There’s no hostile mobs inside, so you don’t have to worry about bringing battle outfits or healing items with you. You can take your time exploring every corner without any pressure.
The first area you’ll find has 12 hidden Star Fragment collectibles, which you can trade for limited-edition hair accessories at the Misty Forest merchant. If you go further into the back of the cave, you’ll trigger a side quest called The Lost Firefly Colony, which rewards you with the exclusive Glow-in-the-Dark Dress outfit upon completion. There’s also a hidden fishing spot in the underground lake at the very end of the cave, where you can catch the rare Cave Koi fish that’s required for one of the game’s hardest collection achievements.
The Gloomy Cavern also has a small hidden chest behind a rock formation near the underground lake, which holds 500 free in-game coins, so make sure you don’t miss that when you’re exploring. I only found it on my third visit, when I accidentally tripped over the rock while chasing a firefly.
Common Mistakes to Avoid When Trying to Unlock the Cavern
After talking to dozens of other players in the official Infinity Nikki Discord, I’ve found that most people who struggle to open the cavern are making the same small, easy to fix mistakes. Knowing these ahead of time will save you a ton of frustration.
The most common mistake is trying to open the door during the day. Even if you have all the right items, the pedestals won’t activate when the sun is up, so you’ll waste your Glowmoss Clumps if you try. Another mistake is using the wrong emote in front of the door – a lot of players use the regular Sing emote instead of the Forest Lullaby one, which does nothing to trigger the unlock. Finally, don’t leave the area after you place the Glowmoss Clumps, because they’ll despawn if you go more than 100 feet away from the door, and you’ll have to start over.
If you do accidentally make one of these mistakes, you don’t have to wait for a cooldown to try again. Just exit the game and restart, or fast travel to a different waypoint and come back, and all the pedestals will reset so you can try again. Just make sure you don’t use all your Glowmoss Clumps on failed attempts, because they take 24 in-game hours to respawn after you pick them. A lot of players assume you need a paid outfit to access the Gloomy Cavern, but that’s a total myth – every part of the unlock process is 100% free for all players.
Unlocking this hidden area is one of the most rewarding small side activities you can do in the Misty Forest, and the exclusive rewards are more than worth the small amount of effort it takes to unlock. Now that you know how to open the gloomy cavern infinity nikki, you can grab the rare materials and exclusive outfit pieces that most players never even know exist.
