At BlizzCon 2026, Blizzard detailed the next major Diablo IV update: the Season of Hell's Legacy. Marking the pinnacle of the franchise's 30th-anniversary celebrations, the new season kicks off on September 15 in the US (September 16 in Japan). But the release date isn't the only headline-grabber. We're looking at the return of Deckard Cain, brutal showdowns against echoes of Diablo, Baal, and Mephisto, and the official confirmation of the Amazon class for 2027.
What's Happening?
During the Diablo IV: What's Next panel and the official Blizzard News post, the studio described the season as a nostalgic deep dive through Sanctuary's storied history. Deckard Cain's soul returns—not as a simple ghost, lead designer Daniel Tanguay explained in an interview with 4Gamer, but inhabiting a borrowed vessel—to warn players that three Dark Wanderers have reawakened, each once serving as a host to one of the Three Prime Evils.
Players will plunge into these characters' darkest nightmares, defeat the echoes of Diablo beneath the Cathedral of Tristram, Baal at Mount Arreat, and Mephisto in the Prison of Hatred, while collecting Splinters of Evil. You can only carry one splinter at a time, and each unleashes an iconic combat power—fire for Diablo, ice for Baal, physical for Mephisto—while dynamically altering specific endgame activities.
How It Works in Practice
The new Waking Nightmares come in three scales. The largest are multi-tiered, capstone-style dungeons featuring reconstructed classic encounters. Medium-sized ones revisit legendary locations like Diablo II's Cave of Evil. The smallest manifest in the open world, pitting players against classic bosses like Queen Araneae or waves of Flayers.
Alongside the Prime Evil splinters, we have Soul Splinters, seasonal gems tied to Andariel, Lilith, the Black Soulstone, and other series legends. You can equip up to three at once. Nine legacy Uniques are also joining the game permanently, including the Crown of Leoric and the Stone of Jordan.
Quality-of-life updates include Rebirth: converting an Eternal realm character straight to Seasonal, dropping back to level 1 without grinding a brand-new character from scratch. War Plans now share progress across alternate characters on the same realm. Meanwhile, the Horadric Cube gains new recipes to reroll affixes and instantly transform a Unique straight into a Mythic while preserving your hard-earned affixes.
The Amazon Returns in 2027
Diablo II's legendary female warrior class makes her triumphant return to Diablo IV in early 2027 via a paid class pack. Tanguay outlined four distinct archetypes: two classics—bowzon and javelin—alongside two brand-new playstyles. Javelins act as a ranged one-handed weapon that can now be paired with a shield for brutal close-quarters combat. Game director Brent Gibson noted the goal is to bridge the gap for players who joined the franchise with Diablo IV and those who remember what made the Amazon truly iconic in Diablo II.
What This Means for the Game
Blizzard recently announced Diablo 5 for 2029 alongside the Age of Hatred collection for Nintendo Switch 2. Even so, Diablo IV continues to receive massive, content-heavy seasons, brand-new classes, and permanent system overhauls. The Season of Hell's Legacy is intentionally nostalgic: Cain, Tristram, the Prime Evils, and legacy items that veterans will instantly recognize.
For players whose journey started with Diablo IV, it serves as a guided tour through the series' rich mythology. For those who grew up playing Diablo II, it's a golden chance to revisit those defining moments under modern mechanics. While it doesn't replace the hype for Diablo V, this season delivers immediate high-impact content while the next numbered entry is still years away.
