There are a few materials in Monster Hunter Wilds that are just easier to find than others. This could be due to their chances of dropping from slaying a certain creature or their abundance when found out in the open world. It also could come down to being found consistently in the same place, meaning that once a player knows where it is, they won't ever have to worry about finding it somewhere else. The Regal Jewel Scarab falls into this category and is a breeze to come across once you know where you need to go in order to find it.
