In Infinity Nikki, there are four Caverns on the Firework Isles, with Behind-the-Mountain Cavern being one of them. Unlocking the Behind-the-Mountain Cavern Door requires activating three Firework Launch Tubes scattered across the world. Each tube requires the Fiery Glow outfit to ignite the fireworks, unlocking access to the hidden cavern and its rewards. However, finding these tubes can be a bit tricky, as they are hidden in various locations across expansive areas. In this guide, we’ll explore the exact locations of these Firework Launch Tubes and explain how to activate them, so you can easily open the Behind-the-Mountain Cavern Door and uncover the mysteries within. Let’s get started!
Infinity Nikki: Behind The Mountain Cavern Door Firework Locations
In Infinity Nikki, activating the Firework Launch Tubes is crucial for unlocking the Behind-the-Mountain Cavern Door. The Cavern is situated just north of Clearheart Lake. To reach it, teleport to the Songbreeze Highland Foothills Warp Spire and then head northwest towards the base of the hills. These tubes are located in three distinct areas, and here’s how you can find and activate them:
Southeast of Songbreeze Highland Foothills Warp Spire:
The first launch tube for the Behind the Mountain Cavern vault is located southeast of the Songbreeze Highland Foothills Warp Spire, near the winding path. Defeat the Esselings that guard it, then activate the tube using the Fiery Glow outfit.
East of Fireworks Peak Warp Spire:
The next tube is situated east of the Fireworks Peak Warp Spire. Teleport there, then glide eastward until you spot the tube atop a mountaintop. Activate it using the Fiery Glow ability.
Northwestern Island of Relic Isles:
The final Behind the Mountain Cavern launch tube is located on the northwestern island of the Relic Isles. Warp to the Crescent Shoal spire, then navigate through the ruins to reach the tube and launch it.
Once all three tubes are activated, the Behind-the-Mountain Cavern Door will open, revealing new rewards and lore.
Activating the Firework Launch Tubes in Infinity Nikki
In Infinity Nikki, activating the Firework Launch Tubes requires using fireworks crafted with the Fiery Glow outfit. Here’s the process:
- Craft the Firework: First, make sure you have the Fiery Glow outfit. Then, gather materials like Sizzpollen and Blastpollen to craft fireworks. For instance, to craft the Victorious Firework, you’ll need 2 Sizzpollen and 3 Blastpollen.
- Load the Firework: Once you’ve crafted the firework, approach the Firework Launch Tube and load it. Make sure the Fiery Glow outfit is equipped, as it is necessary to activate the tube.
- Launch the Firework: Use the Fiery Glow outfit’s special ability to ignite the firework and launch it, activating the tube.
By following these steps, you’ll unlock the Behind-the-Mountain Cavern Door, granting you access to rewards and further story elements.
Rewards
Once you’re done activating the Firework Launch Tubes, return to the Behind-the-Mountain Cavern, where the gate will be unlocked. Enter the cavern and collect the rewards from the chests. Some chests will grant you 5 Diamonds, while one will provide 30 Diamonds. Unlike the Gloomy Cavern, you won’t be able to proceed further, as the gate leads only to a simple room filled with chests.
In addition to the treasure, there are several Dew of Firework scattered throughout the Cavern, which you can collect and exchange for rewards with an NPC named Vita on Sparkheart Island. Stylists can also find a Whim Balloon within the Cavern, which can be given to Vita in exchange for various rewards, including Diamonds and Sketches.
Tips
Defeating Esselings: Players online have suggested using the Fiery Glow outfit’s abilities to take down Esselings guarding the launch tubes, particularly at the Songbreeze Highland Foothills Warp Spire.
Navigating Terrain: In places like Fireworks Peak, where the launch tube is located atop a mountain, it’s recommended to use gliding and climbing techniques to reach these high areas.
Resource Gathering: Gathering materials such as Sizzpollen and Blastpollen is crucial for crafting the required fireworks. It’s advised to thoroughly explore specific regions to collect these resources.
