Grinding away at dungeons in Diablo 4 will have you mindlessly slaying enemies as you slowly level up and find useful loot. While there are dozens of dungeons to dive into, you will likely find some that you prefer over others. If it is filled with more challenging enemies to expedite your gains, you likely will want to keep running through them. Here is how to reset dungeons in Diablo 4 so you can do that.
How to reset a dungeon in Diablo 4
To reset dungeons in Diablo 4, you must pull up the world map and open the quest journal by pressing the left d-pad on a controller or Q on a PC. At the bottom of the side quest section, you will see an option to Reset Dungeons. You must be outside of a dungeon for it to happen. Hold the indicated button, and the game will ask you to confirm if you want it to happen. This will completely reset any side or Nightmare Dungeons but will not affect campaign ones.

Why should I reset dungeons in Diablo 4?
People like to reset their dungeons in Diablo 4 so they can start from the beginning and grind out kills on enemies within that same dungeon quickly. Whether you are trying to get better gear or stack XP to level up, this is a good method to quicken that process. For the best results, you will want to run through the main parts of the dungeon, killing any elite enemies and big groups.
Once you reach the entrance to the boss arena, leave the dungeon, reset, and go through again. If you really want to fight the big boss at the end, you can, but purely on a time-invested model, it’s faster to skip that, especially when playing solo. If you don’t do this, the dungeon will reset itself after a certain amount of time.
