Well to be honest, no one should be out there all day grinding for them. Should be breaking up the grind with other activities regularly to give yourself a break from it. People could probably try to pass off doing a dungeon once an hour as a method for making atma grinding easier, and people would believe it lol.
Go back and look at everything. It's never obvious, but there is always something there to assist you in figuring things out. If it's not left totally to an RNG, then they will drop subtle hints at things.
