To the Edge of the Abyss is the third and final quest required to unlock Diablo 4‘s new Infernal Hordes mode, so it’s a pretty major part of the new season.
This third Diablo 4 season five quest tasks you with delving all the way into Hell, battling huge hordes, and then defeating the Fell Council. While it sounds easy, there’s a lot that can go wrong if you don’t prepare or know what to do. With this guide, you should hopefully make it out of the depths of Hell without (too much) trouble.
