Blizzard outlines more details on what to expect from the Diablo franchise's first ever paid battle pass.

Diablo IV will have a paid battle pass complemented by a rotating seasonal structure of content. Blizzard has confirmed that Diablo IV will not go live with a season--instead, season 1 will release weeks after the game launches in June 2023. So that early access pre-order bonuses will not give players an extra lead over others.
"The battle pass will last for the entire duration of a season. That season is 3 months, so you'll have plenty of time to work your way through the battle pass. Active players will have no problem with that. You're not going to run out of time," game director Joe Shely said.

Luckily gamers won't have to do specific battle pass objectives in order to rank up. Diablo IV associate game director Joseph Piepiora explains:
"You'll be earning progress by completing content in the season journey, but also buy killing monsters, going through dungeons, completing quests--everything you do is going to be slowly earning progress towards your battle pass."
"The season journey is an opportunity for people who don't even have the battle pass to actually go through and have something similar to what they experienced in Diablo III in earning things and so forth," Diablo community lead Adam Fletcher said.


The team will reveal much more info about the battle pass and seasons in upcoming live stream updates in the coming months.
Diablo IV releases on June 6, 2023 for PS4, Xbox One, PS5, Xbox Series X/S, and PC, complete with couch co-op play on consoles.
