Subdetection Unit in Genshin Impact: where to find and buy

In Genshin Impact The Subdetection Unit is local curiosity of Fontaine, which is required to ascend some heroes. You will need quite a few of these detection sub-units, so in this guide we decided to show you where you can find and buy them.

What is the Subdetection Unit for in Genshin Impact ?

At the moment, it is needed to level up only one character - Wriothesley. However, even to raise just one hero you will need 168 pieces of these metal bugs, so you should prepare for their long-term farming and collect the required amount of materials in advance.

Preparing to assemble the Miniature Detector

Featured Characters

You can collect these miniature detectors with any heroes, but if you plan to seriously engage in their farming (that is, make not a 5-minute sortie, but arrange a real Into the Woods for 30-40 minutes), then we recommend taking several characters into your squad who will allow you to significantly reduce the time it takes to collect this wonder. All of them are listed in the table below.

Don't forget to also bring plenty of dishes for endurance and add them to your NRE so you can use them instantly.

How long does it take for the Miniature Detector to respawn?

As is the case with other types of local curiosities, these robobugs, once collected, are restored exactly after 48 hours real time. Therefore, after visiting the best places for farming, just wait a couple of days, and then follow these routes again or ask to go to your friends’ worlds.
