Working out how to earn Resplendent Sparks in Diablo 4 can be a bit confusing, especially as Blizzard has changed the game quite a bit since this rare resource originally appeared. If you didn't know, you can use Resplendent Sparks to craft Mythic Uniques—what Uber Uniques are called nowadays—but you can only get a limited number via certain endgame activities.
It used to require four Replendent Sparks to craft one of these powerful items, but since then the crafting cost has decreased, as well as the number of ways you can actually get the resource. They no longer drop from defeating Tormented bosses, for example.
