Battle passes will also refresh every three months, timed to new seasons. Objectives reward you with things like crafting materials and legendary aspects for the Codex of Power (which enhance your character’s skills in a similar manner to legendary loot items) - and also Favor, the resource that levels up Diablo 4’s battle pass. One change here is that you will no longer have to complete every single objective in a chapter to progress to the next one, allowing you to pick and choose somewhat based on your playstyle.
DIABLO IV SINGLE PLAYER SERIES
Guiding you through each season will be a Season Journey similar to Diablo 3’s, which is basically a series of achievement-style objectives to complete, organized into chapters.
DIABLO IV SINGLE PLAYER PATCH
Each season will also bring standard patch content like balance changes and quality-of-life improvements.

Your seasonal character, however, will be moved to the Eternal Realm at the end of the season, where it will remain playable. The season will introduce fresh questlines, separate from the campaign narrative, as well as new gameplay features that will change the experience of leveling and developing your new character - all of which will be exclusive to the season and will be retired at the end of the three months. You’ll need to complete the game’s campaign on one character before you can access it. Seasons in Diablo 4 will be quarterly, with the first coming in “mid to late July” - a matter of weeks after the game’s launch on June 22. Oddly, Blizzard does not go out of its way to explain this, perhaps assuming that it will be taken as read by the Diablo community, but it has been confirmed in previous interviews. The takeaway is that it all sounds pretty standard for a live service game, with one twist - there’s a heavy focus on seasonal content that, as per Diablo tradition, can only be accessed by starting a fresh seasonal character. It's a bit disappointing to hear the threshold for items being save is legendary, but it's also nice to know that we don't have to worry about losing progress or the best stuff in the upcoming very promising game because of minor server issues or problems on our own side.Blizzard has detailed its plans for the post-launch Diablo 4 experience in a fresh livestream and developer blog, focusing on seasons, battle passes (including pricing), and the shop. The same applies to story progression and such. He also specified that items you pick up and collect will be saved the very second you pick them up, so stuff in your inventory will never be lost due to connection errors or something like that. The really valuable things won't be gone forever". The rare or magic items that were around will be missing at that point, but any legendary items will be back at your stash. So let's say a legendary items drops on the ground and you have a random disconnect happen to no fault of your own and you're not able to reconnect for like five or ten minutes. But items that you have "lost" because of a disconnect are sent to your stash if they are of a certain quality. I believe they are set at three minutes right now, so you can reconnect to the game you were disconnected from in its current form. Piepiora's answer was fortunately a bit reassuring: That's why I had to ask about this when I got the pleasure of talking with John Mueller and Joseph Piepiora, the art director and associate game director respectively.

I was far from the only one that got a bad feeling when Blizzard confirmed Diablo IV will be an always online game last year, as many of us have lost a lot of progression and/or items because of power outages, a bad provider or something in games through the years.
