⚠️

Critical: Permanent Loss Risk

The ESR Analyzer is a Quest Item. It cannot be sold, recycled, or used in crafting. If you die during extraction without a Safe Pocket augment equipped, the item is permanently lost and you must re-farm it. There is no trader backup, no insurance, no second chance.

ESR Analyzer Spawn Points

💊

Piazza Arbusto Pharmacy

Buried City — Southeast Quadrant

Likely spawn point. Search all tables inside the building.

🏛️

Plaza Rosa Pharmacy

Buried City — Central Plaza

Secondary location near the main plaza. ARC foot traffic is higher here.

The ESR Analyzer only appears in Pharmacy buildings marked with a green cross inside Buried City. Generic supply crates do not contain this item.

Completing "A Reveal in Ruins"

Unlike other high-value loot, the ESR Analyzer is entirely tied to quest progression. It weighs only 0.25kg, cannot be sold to vendors, and cannot be broken down for materials.

"Critical Warning: The ESR Analyzer is NOT protected by standard insurance. Equip a Safe Pocket augment before attempting this run, or you will lose the item permanently on death."

Buried City Extraction Plan

This item does not spawn in regular weapon lockers. It exclusively spawns inside Pharmacy buildings (marked with a green cross) within the Buried City underground dungeon.

  • Piazza Arbusto: The southeast quadrant Pharmacy. Often heavily patrolled by basic ARC units.
  • Plaza Rosa: Central plaza Pharmacy. High risk area with frequent drone activity; bring EMPs.

Once acquired, move directly to a Metro Station extraction point. Do not detour for side loot. Upon successful extraction, return directly to Lance at the faction hub to trigger the delivery dialogue and complete the quest.
