All Sub-Discovery Unit Locations in Genshin Impact

Sub-Discovery Block is a local delicacy of Fontaine that can be found in the northern parts of the region. It is an artificial component created by the Fontaine Research Institute to monitor environmental data that visually appears as a mechanical error. Sub-detection modules are used as Ascension materials for Wriothesley and possibly other Fontainean characters in the future. There are a limited number of them in the wild, so I recommend collecting them whenever you come across them.

The sub-detection unit looks like a mechanical error that glows blue and red, but it is still difficult to detect because it is so small. Although visually similar to a scarab, it doesn’t move or run away, so you won’t have too much trouble picking it up.

Most of the Sub-Discovery units are scattered across the northern Liffey Fontaine region, and there are not enough of them to fully Ascend a character in one day. If your world has run out of them, I recommend entering a friend’s world through co-op mode and asking them if you can farm in their world.
