Diablo 4 Season 15: Season of Hell's Legacy

• Power Leveling: Desired Level Range
• Starter Pack: Ready to Start Playing
• High Tier Bundle: Strong Character
• Uber Tier Bundle: Powerful Character
• Torment Tier Bundle: Excellent Minmax Equipment

The questline is led by the spirit of Deckard Cain and sends you after echoes of three Prime Evils: Diablo beneath Tristram Cathedral, Baal at Arreat Summit and Mephisto in the Durance of Hate. Each fight yields a Splinter of Evil. You bear one at a time, and an Iconic Power of that Prime Evil erupts from you in combat: Fire for Diablo, Cold for Baal, Physical for Mephisto. The Splinter also makes you more vulnerable to its own Prime Evil.

• Splinter of Terror (Diablo): modifies Helltide and Infernal Hordes.
• Splinter of Destruction (Baal): modifies The Undercity and Lair Bosses.
• Splinter of Hatred (Mephisto): modifies The Pit and Nightmare Dungeons.

All three also modify the Tree of Whispers, and every track holds eight activity modifiers and six upgrades to the Iconic Power. Prime Evil Power Leveling raises one of these tracks.

Waking Nightmares are encounters rebuilt from Diablo's past, in three sizes. The largest are multi-level Capstone dungeons that recreate showdowns with the Prime Evils; they come back as pinnacle Capstones at Torment 10 and higher. The second kind are standard-length dungeons at fixed locations, such as the Den of Evil from Diablo II. The smallest are one-room fights in the open world, against a past boss like Queen Araneae or waves of monsters like Flayers. Waking Nightmares Boost sells runs of these dungeons.

Soul Splinters are the season's special gems, each tied to a demon or an artifact, such as the Splinter of Anguish for Andariel or the Splinter of Pain for Duriel. They give a boon and carry a liability, up to three can sit in jewelry slots, and the Horadric Cube can raise them to the next rarity. See Soul Splinters Farm.

War Plans came with Lord of Hatred, and this season the reputation you earn in them is shared across the characters of one account that sit in the same realm type, mode and Solo Self-Found setting. Each character still allocates points in its own planner. War Plans Boost, Echoing Hatred Boost and the Lord of Hatred Campaign Boost cover the systems the season relies on. Blizzard notes that about 15% of the Seasonal Objectives need the expansion, including those required for Rank VIII and for all Season Rank rewards.

Nine legacy Uniques arrived with the season as permanent additions on both Seasonal and Eternal realms. Leoric's Crown, Nemesis Bracers and Stone of Jordan are among the pieces that suit every class; Arioc's Needle, Henri's Perquisition, In-Geom, The Furnace and Messerschmidt's Reaver are open to several classes. Lots exist for Leoric's Crown, Stone of Jordan, Nemesis Bracers, Arioc's Needle, Henri's Perquisition, In-Geom, The Furnace and Messerschmidt's Reaver. Since patch 3.2.1 every Unique can drop from level 1 and on any difficulty.

Mythic Uniques can be made in three ways this season: the Horadric Cube recipe that upgrades a chosen item directly to Mythic, the Jeweler's rune crafting, and the Blacksmith's Mythic cache, which has a second version that rolls only Iconic Mythics. An item made through the Cube recipe carries a Crafted tag, and only one such item can be worn at a time. Mythic Unique Gear and the Mythic Items section cover the results.

The Season Rank has nine ranks and 125 objectives. Its rewards include up to 14 Skill Points, up to 42 Paragon points, up to 10 Resplendent Sparks and five Mythic Unique Caches. Smoldering Ashes, earned from objectives and chapter rewards, buy Season Blessings: the Urns of Curiosities, Reclamation, Masterworking, Glyphs and Ancestral Whispers. Rebirth turns an Eternal character into a Seasonal one at level 1, keeping its class, name, appearance and mode. See Season Rank, Favor Tokens and the Season Starter Bundle; leveling lots such as Power Leveling and the Torment Difficulties Unlock sit in this section as well.

When did Season 15 start?

On 15 September 2026, with patch 3.2.1. Characters of the previous season moved to the Eternal realm when the season changed.

Do I need Lord of Hatred for Season 15?

Not for every part, but about 15% of the Seasonal Objectives need the expansion, including those required for Rank VIII and for all Season Rank rewards. War Plans and the Talisman are Lord of Hatred systems.

Are the Legacy Uniques seasonal?

No. Blizzard describes them as permanent additions, available on both the Seasonal and the Eternal realm.

Which lots in this section depend on the season?

The Prime Evil, Waking Nightmares, Soul Splinters and Season Rank lots belong to Season 15 itself. They are reviewed when the next season is announced.
