The Hunting Grounds in Horizon Zero Dawn offer players a chance to test their archery and tactical speed against dangerous machine herds. Among these challenges, the Parts Alone Trial stands out as a test of precision and component removal under a strict time limit. Completing this trial and earning a Blazing Sun reward requires full understanding of your equipment and enemy weaknesses.

Location and Objectives of the Parts Alone Trial

The Parts Alone Trial is located at the Valley-Meet Hunting Grounds, which players encounter relatively early in their journey through the Carja Sundom. The primary objective is to detach processing units from the undersides of Tramplers using specific weaponry before time runs out. To achieve the top Blazing Sun mark, Aloy must remove four processing units within one minute and thirty seconds.

Preparation is crucial because Tramplers tend to move in tight groups alongside other aggressive machines like Scrappers. Entering the arena without the proper weapons or modification coils makes hitting the small component targets significantly harder. Ensuring you have the proper gear equipped before sliding down the rope will save precious seconds.

Essential Equipment and Ammo Requirements

To successfully shoot off the processing units, players should rely heavily on Tearblast Arrows fired from a Sharpshot Bow. Tearblast Arrows emit a high-frequency sonic blast that strips components instantly without dealing heavy lethal damage to the machine body. Standard arrows or elemental attacks are far less efficient and will likely cause you to fail the time limit.

It is also beneficial to equip armor that offers fire resistance or melee protection to absorb incoming damage while aiming. Modifying your Sharpshot Bow with handling coils increases reload speed, allowing you to fire multiple Tearblast Arrows in quick succession. Fast weapon handling ensures you can target several Tramplers before the herd scatters across the valley floor.

Step-by-Step Execution for a Blazing Sun

Begin the trial by sliding down the zipline nearest to the dense cluster of Tramplers. As soon as Aloy drops to the ground, use Focus or Concentration mode to slow down time and pinpoint the glowing processing unit beneath a Trampler's belly. Aim a Tearblast Arrow directly at the underbelly container to strip the component in a single blast.

Once the first component drops, quickly dodge away from the Trampler's counterattack and target the next nearest machine in the area. Repeat the process immediately on four different Tramplers while ignoring any surrounding Scrappers that attempt to intervene. Maintaining momentum and staying mobile prevents the herd from surrounding you during the trial.

Overcoming Common Challenges and Herd Aggro

One of the biggest obstacles during this challenge is managing the aggressive responses of the entire herd once combat begins. Detaching a processing unit causes the Trampler to ignite in flames and burst into a furious melee charge. Staying light on your feet and rolling sideways helps you avoid flame trails while setting up your next shot.

If the herd spreads out too far, restart the trial at the groundskeeper to reset machine positions for optimal grouping. With clear aiming, proper Tearblast ammunition, and swift dodging, earning the Blazing Sun tier becomes a straightforward task for any skilled hunter.
