Diablo IV's anniversary season starts September 15

Blizzard will launch Diablo IV's Season of Hell's Legacy on September 15, using the new season to mark the Diablo series' 30th anniversary.

The season brings back Deckard Cain and the Echoes of Mephisto, Baal, and Diablo. As outlined in Blizzard's panel recap, its Waking Nightmares dungeons revisit battles, encounters, and recreated locations from earlier Diablo games. Nearly 20 returning bosses are included, among them Nihlathak and the Maggot Queen, alongside returning characters such as Leah.

Nine legacy Uniques, including Leoric's Crown and the Stone of Jordan, will make their permanent debut during the season. Players will also be able to use the Horadric Cube to upgrade a Unique item into a Mythic while retaining its affixes.

Less starting over

Rebirth returns, allowing players to carry a character's identity and legacy between seasons. War Plans progress will also be shared between account characters within the specified Seasonal/Eternal, Hardcore, and Solo Self Found partitions. For players who maintain multiple characters, that should mean less repeated progress within those boundaries.

Amazon planned for 2027

Blizzard also confirmed that the female-only Amazon class is planned to arrive through a Class Pack in the first half of 2027. The class will have four archetypes: Champion, Skirmisher, Ranger, and Commander. Blizzard has not announced a release date beyond that window or a price for the pack.
