Wait for a readable scene
Finish the game action that needs your attention before using the companion. Where practical, let large combat effects clear and move menus or tooltips away from the intended target. The scanner receives an image, not your intention or the full history of the encounter.
Choose one visible subject near the capture centre. An eligible object near the edge can be less useful than an unambiguous central target. A decorative prop that resembles storage is not necessarily a loot-bearing container.
Check the capture position
Know whether your configuration follows the cursor or the screen centre. If a scan repeatedly lands beside the target, review the position mode and saved offsets in scanner settings rather than compensating blindly with repeated paid captures.
Use trial mode when testing a new resolution, monitor arrangement or capture setting. Look at the returned image to confirm that the intended subject is present. A clear capture can still return no loot when the subject is ineligible or has already been scanned.
Read the outcome before the next run
Companion rewards are separate from the ARPG's own item drops. A successful in-game fight, chest interaction or lucky in-game drop does not guarantee a companion reward or improve its result.
If you receive a fulfillment error after a charge, stop repeating paid scans of the scene and check inventory, email and transaction history. Keep the approximate time and scan reference for support. Distinguishing image quality from service failure is more useful than simply increasing the number of attempts.
