So finish up what you were doing before switching your quests!Īfter clicking OK, then you should notice your current quest change in the main menu:Īnd now when you start the game your friend can join you. Note the warning: the only drawback to this is you lose all progress for your current quest. Then select Normal Difficulty from the drop list:Īnd finally select the any quest (here I select Prime Evil) and click the Select Quest button: Note that this doesn't mess up your save file or anything you will be able to return to your previous quest and difficulty after you've played with your friend.įirst click the Change Quest button in the main menu (notice I am currently on Hell difficulty):

So if you want your friend to play with you, change your quest to a quest on their difficulty. Unlocking quests doesn't matter only unlocking the difficulty does. One important thing to note is that the only restriction for friend joining you is that they have unlocked the difficulty you are playing on. If your friend just buys the game you can join him in his quests, but he cannot join you until he has unlocked the difficulty you are playing on. If it is private, message them asking for an invite. You can join a friend's game without invitation unless it is private. You must be online when playing Diablo 3, so you can join your friends whenever you want. Edit: There are now level restrictions: you must be 25 to advance to Nightmare, 50 to advance to Hell, and 60 to advance to Inferno. This follows for other difficulties as well.

You'll have to defeat all 4 act bosses and complete the Prime Evil quest on Normal difficulty to go to Nightmare and play with your friend who is on Nightmare, and you'll have to redo this process for any character you create. You can only create a character starting on Normal difficulty.
