Guide: How To Get Fallout 76 Hardened Mass

Hardened Mass is a valuable resource in the game that can only be collected from timed biomes known as Blast Zones.

Hardened Mass is yet another important resource that players can find in the massive map of Appalachia. However, unlike Black Titanium and Fusion Cores, this is not simply found on random enemies or in treasure chests.

It is not an item that is used to craft usable items directly. It is a component that is mixed with multiple other ingredients at Chemistry Stations to turn raw flux into stable flux, which is then used for crafting recipes.

One of these recipes is for the Fusion Core, which is essential for operating Power Armor in the game. We extensively went over the process of getting these in our guide.

Be careful not to confuse this item with the Fusion Cores in Fallout 4 though. With that out of the way, let’s move on to procuring Hardened Mass.

Key Highlights
  • Hardened Mass is a material in Fallout 76 obtained from dead creatures within Blast Zones.
  • Blast Zones are temporary biomes formed after a nuclear warhead detonation.
  • To farm Hardened Mass, players rush into Blast Zones, kill enemies, and loot their bodies before the area resets.

How To Find Hardened Mass?

A Blast Zone.

Unfortunately, there are no set locations or enemies in the game that will yield Hardened Mass. So if you wanted to find farming spots, we couldn’t help you even if we wanted to. This material is only found on dead creatures within Blast Zones.

For those who may not already know, these are not marked areas in Fallout 76. They are temporary biomes created as a result of the fallout from when a nuclear warhead is detonated. The resulting irradiated area is then known as a Blast Zone.

When a nuke is detonated on the server you’re playing on; you can rush into the Blast Zone created in its wake to collect a bunch of Hardened Mass. All you have to do is kill as many enemies as possible and loot their bodies before the area resets back to normal.

Each Blast Zone only has a two-hour time limit, so it’s recommended that you don’t waste time in reaching it. Because if you miss this opportunity, you’ll have to wait three whole hours before another bomb can be detonated on that same server.

But what if no one is launching a nuke on your server at all? What do you do in those situations? Well, you can always detonate one yourself.
