Whenever a new region launches, the first task I do is to collect that region's related oculis. Whether it's a Lumenspar in case of the chasm or electroculi in Inazuma, I head over to the official genshin interactive map or Genshin map sample map to hunt for the oculis or collectibles of that region. Inazuma launched, and some speedrunners in a discord group started collecting Electoculi. Most of the time, the official map updates a bit later, and third-party maps update faster.  A resource I follow is the official Hoyolab app. The community makes posts regarding the game and posts beneficial articles. There are some awesome artifact routes, tips, and tricks about the game that members post, and you can also get your hands on hidden achievements. So, I highly recommend you to check these resources.
