I love the exploration and collection aspect of the game but I can't tell if artifacts are completely random or not. For example, some artifacts spawns are far off the beaten path, do these tend to drop more rare artifacts than an easier spawn? I thought so at first as I got a rare the first time finding an especially hidden spawn point, and several greens in a not-as-hidden but still out of the way area. Since coming back there though I've only gotten whites.
If this is the case, however, do certain artifacts ONLY spawn in certain locations, or does every artifact have at least a tiny chance of dropping anywhere?
I ask if it's not completely random because I love exploring out of the way areas but if you aren't really rewarded in some way for finding more hidden spawns it would seem kind of pointless.
