Diablo 3 Season 40: What to Prepare Before Launch 

Diablo 3 Season 40 is almost here, giving players another chance to start fresh in Sanctuary and work through a new Seasonal Journey. Blizzard has confirmed that Season 39 ends on September 27, 2026, while Season 40: Light’s Calling begins on October 2 at 5:00 p.m. PDT. The new season brings back the Light’s Calling theme from Season 27, along with Angelic Crucibles, returning cosmetic rewards, new End of Journey cosmetics, rotating Conquests, and a new selection of Haedrig’s Gift sets.

For players who are planning to jump into the new season, the days before launch are a good time to organize their account, finish anything important in Season 39, and decide how they want to approach the opening hours of Season 40.

This guide explains what you should prepare before Diablo 3 Season 40 starts, what changes when the new season begins, and what to know before creating your new Seasonal character.
