Where To Find Fossilized Lightning in Arc Raiders

A fresh update has landed in Arc Raiders, and alongside the latest event and balance tweaks, players now have access to a brand-new material with a very specific spawn condition. Fossilized Lightning is tied to a rare weather effect and only appears on four of the game’s maps, making it easy to miss if you don’t know what to look for. Unlike most crafting items you casually pick up during raids, this one requires timing, awareness, and a bit of luck. In this guide, we’ll break down exactly where Fossilized Lightning spawns, how the weather mechanic works, and whether it’s actually worth keeping in your stash or better off selling once you manage to extract it.

Where To Find Fossilized Lightning

Fossilized Lightning is one of the most situational materials you can find in Arc Raiders, and it only appears during the Electromagnetic Storm weather event. You won’t find it inside containers, buildings, or specific points of interest. Instead, this material has a small chance to spawn only after a lightning strike hits the ground during the storm.

When lightning crashes down, there’s a slim chance a large, jagged stone formation will appear right at the impact point. This twisted rock is Fossilized Lightning. The spawn rate is extremely low, so don’t expect one to show up often. Even after dozens of lightning strikes, you might only see a single spawn, making it more of a rare bonus than something you actively grind.

You can tell a strike is coming when bright blue sparks and electrical effects start flashing on the ground. Once you see that warning, you have roughly two to three seconds before the bolt hits. Getting caught in the blast is dangerous, as it can instantly wipe your shields and chunk your health, so staying alert is key.

If you want to slightly increase your odds, stick to open areas with nearby cover, like rock overhangs or broken structures. Let the storm do its thing in exposed spots, then quickly move under cover before the strike lands. That said, Fossilized Lightning isn’t something you need to deliberately farm. You’ll usually stumble across it naturally while moving through the map during an active storm.

The Electromagnetic Storm itself doesn’t last long, typically just over an hour, which translates to two or three raids depending on how long you survive each run. Because of that limited window and the low spawn chance, it’s best to treat Fossilized Lightning as a lucky find rather than a main objective.

Right now, Fossilized Lightning doesn’t have a dedicated crafting use. You can recycle it for three Explosive Compounds or sell it for around 4,000 credits, which makes it a decent cash pickup. If you’re preparing for early progression or stacking currency, selling it is usually the smarter move. Otherwise, holding onto one or two in your stash could pay off later, especially with future updates and wipes potentially giving this rare material a real purpose.

Conclusion

Fossilized Lightning is one of the rarest and most unpredictable materials you can come across in Arc Raiders. Since it only appears during the Electromagnetic Storm and has a very low spawn chance after lightning strikes, it’s not something you should actively grind for. Instead, it’s best treated as a bonus find while you’re already looting or moving through the map during the event. For now, selling it or recycling it makes the most sense, especially if you’re focused on progression or stacking credits. Still, keeping one or two in your stash could be a smart long-term play, as future updates may give Fossilized Lightning a much bigger role in the game.
