Diablo 4 patch 3.2.1 is live, and it is the biggest content drop of the year: the 30th-anniversary Season of Hell's Legacy. The update went out on September 14, 2026 (labelled update 2.18 on PlayStation and 1.118 on other platforms), and the season itself went live on September 15, 2026 at 9:30 a.m. PT. Below is the full, source-verified breakdown of every major change — the new seasonal systems, the endgame reworks, the nine returning Legacy Uniques, and the class balance numbers that actually matter before you re-roll your build.
Quick answer: Patch 3.2.1 launches Season of Hell's Legacy. It adds the Prime Evil Splinter seasonal mechanic, Waking Nightmares dungeons, eight new Soul Splinter gems, the Rebirth system (convert an Eternal character to Seasonal), shared War Plans reputation, more deterministic Mythic Unique crafting, two new Horadric Cube reroll recipes, and nine returning Legacy Uniques. Barbarian was nerfed across the board; Druid received large buffs.

What is the new Prime Evil seasonal questline?
The centrepiece of Season of Hell's Legacy is the return of Deckard Cain — "the lost soul of the legendary Horadrim Deckard Cain returns with dire news." Three dark wanderers have come back, and the seasonal questline sends you into the nightmares of their pasts.
You collect the three Splinters of Evil by defeating:
- Diablo beneath Tristram Cathedral
- Baal at Arreat Summit
- Mephisto within the Durance of Hate
You then choose which Prime Evil's power to bear, build reputation through that Splinter's activities, and unlock modifiers and upgrades through War Plans. When you want to switch, you return to the largest Waking Nightmares to change the Splinter you wield.
Bearing a Splinter turns you into a dark wanderer: an Iconic Power periodically erupts from you in combat — Fire damage for Diablo, Cold for Baal, Physical for Mephisto — but it also makes you more vulnerable to that same Prime Evil. Each reputation track has eight activity modifiers and six upgrades to the Iconic Power.
Which activities each Splinter modifies
Which content should I run for each Prime Evil Splinter? Each Splinter reshapes a different slice of the endgame, so pick the track that matches the content you already grind:
| Splinter (Prime Evil) | Iconic damage | Modifies these activities |
|---|---|---|
| Splinter of Terror (Diablo) | Fire | Helltide, Infernal Hordes |
| Splinter of Destruction (Baal) | Cold | The Undercity, Lair Bosses |
| Splinter of Hatred (Mephisto) | Physical | The Pit, Nightmare Dungeons |
| All three | — | Tree of Whispers |
You can only bear one Prime Evil Soul Splinter at a time; acquire another from the largest Waking Nightmares to swap tracks.
Waking Nightmares: three tiers of throwback dungeons
Waking Nightmares are memory-dungeons rebuilt from Diablo's history, and they come in three sizes:
- Largest — multi-level, Capstone-type dungeons recreating the historic Prime Evil showdowns. First seen in the questline, then replayable on Torment. Like all Capstones they have a fixed difficulty, and they also appear as pinnacle Capstones at Torment 10+ for bigger loot.
- Standard-length — normal-dungeon-sized recreations (for example the Den of Evil from Diablo II) with fixed world locations.
- Smallest — one-room open-world encounters that appear suddenly, throwing you against a past boss like Queen Araneae or waves of Flayers.
Soul Splinters: eight new seasonal gems
Separate from the three Prime Evil Splinters, Soul Splinters are demonic gems you slot into jewelry — up to three at once — each with a boon and a liability. The eight introduced this season:
- Splinter of Anguish (Andariel)
- Splinter of Sin (Azmodan)
- Splinter of Lies (Belial)
- Splinter of the Black Soulstone
- Splinter of Pain (Duriel)
- Splinter of the Mother (Lilith)
- Splinter of Hellfire (Na-Krul)
- Splinter of Damnation (Skarn)
They drop as Magic, Rare, Legendary, or Unique, and you can Amalgamate same-type, same-rarity Splinters in the Horadric Cube to push them to the next rarity.
Endgame changes you'll feel immediately
Shared War Plans reputation
War Plans reputation now shares across your alts as long as they match on all three partitions: Eternal/Seasonal, Non-Hardcore/Hardcore, and Normal/Solo-Self-Found. Each character still allocates its own plan points separately, similar to shared skill or Paragon points.
Hardcore players, read this carefully: only living characters at the end of Season 14 transfer their War Plans points to Eternal. A Hardcore character that dies before the changeover loses its progress. Starting in Season 15, to carry a dead Hardcore character's progress to Eternal you must keep at least one other living Hardcore character in the same partition — even a level 1 "storage" character — to deposit the accumulated points.
More deterministic Mythic Unique crafting
The three ways to make a Mythic Unique are unchanged, but the outcomes are far more controllable:
- Horadric Cube — Upgrade Direct Item to Mythic: more expensive, but a true 1:1 transfer — put in a perfectly tempered and masterworked item and get a Mythic-ized version with every affix retained. These carry a Crafted tag, and you can equip only one Crafted-tag item at a time.
- Jeweler — Rune Crafting → Mythic Uniques: no Crafted tag.
- Blacksmith — Forge → Mythic Cache: no Crafted tag.
After PTR feedback, Iconic Mythics stay Mythic-quality only (the planned Unique-tier versions were scrapped for cheapening them), and the Blacksmith now has a second cache that rolls only Iconic Mythics at the same cost as the standard Mythic Unique cache.
Two new Horadric Cube reroll recipes
- Affix Value Reroll: rerolls all base affixes on equipment and Talisman items (Charms and Seals) while protecting Greater Affixes, Enchanted affixes, Tempers, and Transfigurations.
- Horadric Reroll: for Legendary+ Charms and Seals, fully randomizes base affixes without touching Set Bonuses or Unique/Mythic charm powers.
Nine returning Legacy Uniques
Season of Hell's Legacy adds nine legacy Uniques as permanent additions to both Seasonal and Eternal realms. Items marked (*) also come as Unique Charms.
All classes:
- Leoric's Crown (Helm)
- Nemesis Bracers (Gloves)*
- Stone of Jordan (Ring)*
- Sirloin of the Bovine (Legs)
Multiple classes:
- Arioc's Needle (2H Polearm)* — Barbarian, Druid, Spiritborn
- Henri's Perquisition (Offhand Focus)* — Sorcerer, Necromancer, Warlock
- In-Geom (1H Sword)* — Barbarian, Druid, Rogue, Necromancer, Paladin, Sorcerer, Warlock
- The Furnace (2H Mace)* — Barbarian, Druid, Necromancer, Paladin, Warlock
- Messerschmidt's Reaver (2H Axe) — Barbarian, Druid, Necromancer, Paladin, Warlock
Yes, the Stone of Jordan — "a ring so coveted it once served as currency" — is back.

Quality-of-life and Rebirth
- Rebirth: convert an Eternal character to the Seasonal realm, resetting to level 1 but keeping class, name, appearance, Normal/Hardcore state, and a running tally of hours played across all Rebirths. Move every item to your Eternal stash first — Rebirth will not run until the character has no equipped or inventory items, and you'll be warned that retained items are destroyed.
- Horadric Post: a new one-way "postal box" the dev team uses to deliver rewards, supplies, and commemorative items straight to your account.
Season progression and the 30th Anniversary Battle Pass
Season Rank has nine ranks and 125 objectives, rewarding up to 14 Skill Points, up to 42 Paragon points, up to 10 Resplendent Sparks (plus more in Mythic Caches), 5 Mythic Unique Caches, the Dark Wanderbear pet, the Banner of the Three mount trophy, and more. Note Blizzard's asterisk: ~15% of Seasonal Objectives require the Lord of Hatred expansion, including objectives needed to finish Rank VIII.
The Battle Pass Reliquary is free to all and, for the first time, includes class-specific armor sets. The Deluxe Battle Pass Bundle costs 2,800 Platinum and grants instant access to the Archangel of Justice armor set plus the Lordling of Terror pet and Wings of Justice.

What is the biggest new feature in patch 3.2.1? The Prime Evil Splinter seasonal mechanic — you defeat Diablo, Baal, and Mephisto, then choose one Prime Evil's power to bear, which reshapes a slice of the endgame and grants a periodic Iconic Power at the cost of extra vulnerability to that same evil.
How does Rebirth work in Season 15? Rebirth converts an Eternal character to the Seasonal realm, resetting it to level 1 while keeping class, name, appearance, and Hardcore/Normal state. You must empty the character's equipment and inventory into your Eternal stash first — any retained items are destroyed on Rebirth.
Did War Plans reputation carry over to Eternal? Yes. At the September 15 changeover, War Plans progress from living Season 14 characters carried over to matching Eternal characters. Hardcore characters that died before the changeover did not transfer their points.
Was Barbarian nerfed in patch 3.2.1? Yes. Barbarian's core stat scalar dropped from 1.1 to 0.8, and several key skills, glyphs, and aspects were reduced. Druid, by contrast, received large buffs including a core stat scalar increase from 1.25 to 1.625.
How many Legacy Uniques were added? Nine, including Leoric's Crown, the Stone of Jordan, and Messerschmidt's Reaver. They are permanent additions to both Seasonal and Eternal realms.
