How to use the Subdetection Unit item in Genshin Impact

The Subdetection Unit item is currently only used as a character enhancement material. The only character who can use the Subdetection Unit is Wriothesley, releasing in the second half of Version 4.1. Wriothesley requires the Subdetection Unit for character ascension, so you’ll need to farm these items if you want to level him up to level 90. Other characters will likely use this item in the future, so it’s a good idea to establish these items as a part of your farming route.
