The Fortnite Unstable Element is one of the most talked-about items in Chapter 7, Season 1. Unlike traditional loot, this item is not a weapon or a healing tool. Instead, it works as a key that unlocks hidden vaults found in specific areas of the map. This Fortnite guide explains everything you need to know about the Unstable Element.

What is Fortnite Unstable Element & what does it do?

The Fortnite Unstable Element is an Epic item added in Chapter 7. You cannot use it for damage, mobility, or defense. Its only purpose is to open sealed vault doors that contain high-tier loot such as Epic or Legendary weapons. When you use the Unstable Element on a vault door, the item disappears from your inventory, but the vault opens and gives you access to powerful gear.

Because Fortnite often rewards players who have better early-game loot, the Unstable Element can give you a large advantage if you find it before other players.

Fortnite Unstable Element locations

You can find the Fortnite Unstable Element inside Innoloop Labs, one of the main points of interest in Chapter 7.

The process to unlock it is simple but requires attention because the location is often filled with other players.

• Head to the lab and look for the large Zero Point–like shard in the main room.
• Smash the glass panel beneath the shard to drop into the hidden hallway.
• Enter Tunnel 1 and Tunnel 2, teleporting back and forth.

• After several teleport loops, the Fortnite Unstable Element will appear in your inventory.

You only get one use, so choose your vault carefully.

How to use the Fortnite Unstable Element

With the Unstable Element in your inventory, the next step is finding a vault. These vaults are usually located near hidden doors around the map. Many of them are placed near a portable toilet, which is often used as a visual clue.

Using it is easy:

• Approach the sealed vault door.
• Hold the interact button.
• The Unstable Element disappears.
• The vault opens and reveals high-tier loot.
