The ARC Raiders Week 18 Trials are now live, and this set is one of the easiest opportunities to prepare for the upcoming third expedition. 

If you’re looking to buy ARC Raiders Items or want to know where to buy ARC Raiders Items safely, understanding and completing weekly trials efficiently will save you both time and resources.

Week 18 Trials are designed around enemy interaction, exploration, and smart route planning. With the right strategy, you can clear all objectives in a single run while gathering valuable materials and coins.

Trial 1: Damage Leapers Efficiently

Leapers are mid-tier ARC enemies that rely on jumping and shockwaves. The safest way to damage them is to stay mobile and target their eyes or leg joints.

For fast progress, enter zones with high enemy density during large map events, which grant double trial points. Dam Battlegrounds and Buried City are especially effective.

Recommended locations:

• Water Treatment Control Elevator (Dam Battlegrounds)

• Marano Park (Buried City)

• South of Launch Towers (Spaceport)

Defeating Leapers also yields valuable crafting materials like ARC Alloy and Motion Cores, which can be sold or used to upgrade gear.

Trial 2: Loot Bird Nests in Bird City

This task requires the Bird City map condition on Buried City. While the event isn’t dangerous, it rewards exploration.

Use ziplines across rooftops to move quickly and search near chimneys. Watch out for flying ARC units while looting. Most nest items are best sold for coins, making this trial ideal for economic progression.

Trial 3: Damage Spotters Without Overcommitting

Spotters don’t attack directly but mark your position for Bombardiers. Focus on destroying their thrusters.

Once you damage enough Spotters, disengage instead of farming endlessly, as they respawn in pairs if Bombardiers remain alive.

Trial 4: Open ARC Probes Quickly

ARC Probes emit black smoke and sound cues, making them easy to find. Blue Gate has the highest spawn rate during Prospecting Probes events.

Stick to elevated terrain to spot probes quickly, and prepare for minor enemy reinforcements after activation.

Trial 5: Search Containers in Stella Montis

The Medical Research Wing in Stella Montis is PvP-heavy. Bring low-risk gear and loot during events like Night Raid to maximize rewards without attracting hostile players.
