Congratulations! You’ve made it to Inferno difficulty Act 4. In Act 4, the mobs are still level 63. Thus, you will not experience the brick wall that you experienced between Act 1 and Act 2 Inferno. If you are simply looking for sick gear on runs, I recommend you stay in Act 3. It’s trickier to get 5 stacks of Nephalem Valor when you’re facing bosses like Rakanoth or Izual because Act 4 is much shorter (although it could be an idea to continue an Azmodan run all the way through Act 4). As a Demon Hunter, this act is very much doable. But, if your goal is to beat Diablo in the highest difficulty, you’ve come to the right place!
