In ARC Raiders, your success hinges on the gear you bring to the surface. Among the tactical items available, the Trailblazer Grenade stands out as a top-tier choice for clearing heavy machine threats. However, getting your hands on one isn't as simple as checking a supply crate.

If you want to add this explosive tool to your arsenal, you will need to hunt down its schematic, extract under heavy fire, and gather specific components. Here is exactly how to farm, craft, and utilize the Trailblazer Grenade effectively.

1. Track Down the Blueprint (Night Raids Only)

The first step in your crafting journey requires a trip to Stella Montis. Keep in mind that the Trailblazer blueprint is a night-raid exclusive drop, meaning you'll need to brave the dark when the mechanized threats are at their most aggressive.

Where to look: Focus your search around the Western Tunnel train tracks. If you have the firepower, hunting down massive ARC units like Bastions on this map also yields a high drop rate for the schematic.

Secure the extract: The moment you find the blueprint, immediately drag it into your safety pockets. If you get wiped by a rogue drone or an enemy squad before reaching the extraction point, anything left in your standard backpack is gone.

Unlock the recipe: Once you successfully extract and return to the safety of Speranza, open your inventory, select the blueprint, and hit "Learn and Consume." This permanently unlocks the item at your workbench.

2. Gather the Materials: The Crafting Cost Breakdown

With the blueprint unlocked, head over to the Explosives Station in your workshop. To assemble a single Trailblazer Grenade, you will need to combine three distinct types of components:

1x Firefly Burner: Dropped exclusively by destroying Firefly models floating around the topside ruins.

1x Synthesized Fuel: A high-tech component found near industrial zones, though it can occasionally be purchased directly from Celeste if you have the spare currency.

2x Crude Explosives: A common junk item found throughout the world, which can also be manufactured by processing raw scrap at your Refiner.

For players looking to skip the intense grind of scavenging or who want to gear up their squads instantly without spending dozens of hours hunting specific robot spawns, third-party marketplaces can be a massive time-saver. You can utilize platforms likeU4N to buy arc raiders pc items cheap, allowing you to bypass the resource loop entirely and keep your inventory stocked with high-grade explosives and ammunition for your next deployment.

3. The Best Farm Loop: The Rocket Assembly Building

If you prefer to hunt for the materials yourself, the single most efficient route is located on the Spaceport map. Head directly to the Rocket Assembly Building situated on the southeast side of the complex.

A quick run through this specific building can fully fund multiple grenades:

The Fuel Truck: Check the bed and the ground around the parked truck inside the main hangar. Two to four units of Synthesized Fuel reliably spawn here every match.

The Thruster Trick: Look closely at the metal shelves near the truck. Grab the massive Rocket Thruster item if it spawns. While it takes up significant inventory space, taking it back to Speranza allows you to recycle it for an automatic bonus of two Synthesized Fuels.

Explosive Crates: The green and gray military crates scattered around the perimeter of this hangar have an incredibly high drop rate for basic oil and crude explosives, easily covering your crafting minimums.

4. Combat Application: Melting Heavy ARC Units

The Trailblazer isn't a standard fragmentation grenade; it functions as an area-denial weapon. When thrown, it leaves a dense trail of explosive green gas that hangs in the air for a brief moment before detonating in a massive chain reaction.

Because heavy ARC units like Bastions, Bombardiers, and Leapers have predictable, slower movement paths, you can throw the Trailblazer directly into their incoming trajectory. The gas cloud inflicts continuous damage ticks, stripping away outer armor plating before the final explosion deals its massive burst damage. A single well-placed grenade can completely trivialize an encounter with a heavy machine squad, making the farming loop well worth the investment.
