As Genshin Impact’s latest limited-time challenge pits Travelers against a relentless automaton in 2026, the community is quickly drawing parallels to the classic Version 2.2 Shadow of the Ancients event. The final phase, known as Live Testing, featured an Anomalous Model Ruin Grader with terrifying regenerative abilities – a blueprint that HoYoverse has clearly revisited. For both veterans and newer players facing this revived threat, the original strategies remain surprisingly effective. Here is a comprehensive walkthrough, updated with modern roster options, to conquer the Live Sample quest and its demanding achievements.
Phase 3 Unlock Requirements – Completing the Prelude
Before you can challenge the regenerative Ruin Grader, the preliminary stages must be fully cleared. Adventurers must first wrap up the Phase 1 Investigative Surveys and then finish all Phase 2 Data Sampling objectives. These missions set the stage by reintroducing the Pursina’s Spikes mechanic and the Ayesha’s Chaos Prospector gadget. If you are stuck on any earlier phase, remember that the Journal of the event still offers a detailed progress tracker. Once the prerequisites are met, the final quest – Autonomous Mechanical Energy Source: Live Sample – becomes available.
Deploying Pursina’s Spikes on Tsurumi Island
After activating navigation via the event menu, make your way to Ritou and speak with Hosseini. He will direct you back to Tsurumi Island, the misty land where you originally encountered the Ruin Grader. Your first task mimics the investigative surveys: equip the Ayesha’s Chaos Prospector and scan the area to locate three optimal spots for placing the Pursina’s Spikes. The gadget will pulse when you are near a valid location, making the search straightforward. Once all three spikes are anchored, report back to Hosseini to formally unlock the Live Testing showdown.
Live Testing Battle Strategy – Neutralizing the Anomalous Model Ruin Grader
The central mechanic revolves around keeping at least one Electro character in your party. The Pursina’s Spikes must be fully charged with Electro energy to deliver a final discharge that ends the fight. If any spike is destroyed by the Ruin Grader’s attacks, it is an immediate loss. The Grader itself is relentless, frequently launching powerful laser beams from its legs – the exact moment when its weak points are exposed. A well-timed shot to these glowing weak points will briefly stun the machine, giving you a critical window to charge the spikes or reposition.
An aggressive but controlled approach works best: constantly monitor the spikes’ HP indicators on the left side of the screen. When the Grader targets a spike, you can interrupt it by stunning the machine or by applying consistent Cryo and Hydro to freeze it. The freeze reaction is especially valuable here because it locks the automaton in place, preventing spike damage and letting you hammer at its exposed legs without fear of retaliation.
Achievement Guide and Primogem Rewards
The event offers multiple achievements, but the most lucrative one in terms of Primogems is “Destroy the Anomalous Model Ruin Grader’s weak points 8 times.” This achievement alone demands that you deliberately aim for the legs during its laser attack phase, so build your team around archers or catalyst users who can hit those spots reliably. Another notable challenge asks you to complete the entire fight with all Pursina’s Spikes maintaining over 50% structural integrity. This requires near-perfect crowd control: freeze the Grader, stun it the moment it turns toward a spike, and defeat any accompanying mobs quickly.
Here is a quick reference table for the key battle achievements and their reward types:
| Achievement | Requirement | Reward Type |
|---|---|---|
| Live Testing: Lightning Charge | Clear the event once | Primogems, Event Currency |
| Live Testing: Structural Integrity | All spikes over 50% HP | Enhancement Materials |
| Live Testing: Weak Point Breaker | Destroy weak points 8 times | Primogems |
| Live Testing: Flawless Victory | No spike destroyed | Mora, Talent Books |
Since only the first-time clear and the weak point achievement grant Primogems, you can prioritize those and treat the others as optional. Realistically, most players will need at least three separate runs to collect all rewards.
Optimal Team Composition and Modern Twists
The classic lineup still shines: one Electro, one Cryo, one Hydro, and a flexible fourth slot. A character like Raiden Shogun or Fischl can provide consistent off-field Electro application to charge the spikes while you focus on combat. Cryo options such as Ganyu, Ayaka, or even the ever-reliable Kaeya work wonders for controlled freezes, while Hydro can come from Xingqiu, Yelan, or Kokomi for sustained application and healing. With the expanded roster in 2026, you might also consider a Dendro healer or shielder to add bloom reactions, but be cautious – you don’t want to accidentally overload the Grader and push it out of freeze range.
For the fourth member, an Anemo crowd controller like Kazuha or Sucrose can gather any smaller mechanical adds, or a second strong DPS such as Alhaitham can speed up the fight. If you struggle with survivability, drop the Anemo and bring Zhongli; his shield will let you ignore the Grader’s sweeping attacks while you aim for the legs.
Additional Pro Tips for a Smooth Run
-
Consumable buffs are allowed: this is not a rogue-lite event, so bring Adeptus’ Temptation, Jade Parcels, or your dish of choice. Pop food buffs right before the encounter begins to maximize uptime.
-
Stun the eye when it glows: identical to standard Ruin Guards, the Grader’s central eye flashes before large attacks. A charged arrow or a precise hit with a catalyst can temporarily disable it, buying precious seconds.
-
Leg targeting rhythm: wait for the Grader to initiate its spinning laser or a stomp animation. That is when the weak point indicators appear clearly. Fire off a few quick aimed shots – even a single hit counts toward the 8-time achievement.
-
Freeze chain management: don’t apply Cryo and Hydro all at once; let the freeze duration run out before reapplying. This staggers your stuns and prevents the Grader from building up resistance too quickly.
-
Respect the spikes: if a spike drops below 25%, drop everything and use your burst to immediately push the Grader away. A single Electro-charged spike can win the fight even if the others are low.
Back when Shadow of the Ancients first arrived in November 2021, the community learned that patience and precision were far more valuable than raw damage. As Genshin Impact revisits this style of event in 2026, those same principles hold true. Take your time, lock down the Grader with freezes, and methodically dismantle its weak points. With the strategies outlined above, you will secure every Primogem reward and walk away with a satisfying victory over the regenerative machine.
