Wytchwood does a pretty good job of explaining where to go to find resources, but it does not list every place you can find everything. Hopefully this guide covers that. What you will not find here are maps showing where exactly things are, even the rare ones. Most resources do not spawn in exactly the same spot on the map, but the rarer ones are pretty localized and not difficult to find within their area.

Locations sorted in order of availability while playing the game. Please note that some resources are found in side areas but not the main area. I have done my best to delineate these cases. Also, some resources which require tools or interaction to access (e.g., hacking away at a log to uncover what's within) will not always result in every possible resource. Thus, some resources are more common in some areas and less common in others.

If you have any corrections to submit, please let me know! At this point I consider this guide complete. I had mostly finished it when I discovered there's a fan wiki with this information and more out there, albeit not all in one list like this.

Thanks for reading. Happy hunting!
