On top of upgrading your characters the Naku Weeds are often used in Genshin Impact, while not that hard to find you'll still need a lot of them so here's a guide to where you can get your hands on a bunch.
Naku Weeds Location Genshin Impact
You will be able to find Onikabuto on the following four islands:
- Seirai Island
- Narukami Island
- Yashiori Island
- Kannazuka Island
If you're looking for a more precise location for all these Onikabuto I'd advice checking the official interactive map where you'll be able to zoon as you see fit.
You can find the map on the Hoyolab website here.
If you're looking to upgrade your characters in Genshin Impact some of them will require Amakumo Fruits and here where to find them
