Blizzard has finally revealed all of the Diablo 4 Season 15 content and seasonal mechanics, together with a new battle pass with free and premium rewards. We also know it’s titled Season of Hell’s Legacy.
“Three dark wanderers have returned from Pandemonium—each a former vessel of a Prime Evil, bringing with them the nightmares of their past. Guided by the soul of Deckard Cain, enter their fractured memories, confront the horrors that shaped their fate, and uncover the legacy of Sanctuary’s darkest legends.”
Ahead of the launch date, you can learn all about it via Blizzard, but we’ve put together a quick rundown right here if you want an easier-to-digest version:
- Echoes of Prime Evils can be battled via fractured memories to obtain “rewards infused with the essence of Sanctuary’s most infamous villains”
- Rebirth mechanic to use existing characters (Eternal) in the new seasonal journey
- Channeling the powers of the Prime Evils against the echoes of the Burning Hells, with the new abilities and seasonal rewards based on the series’ past
- Waking Nightmares dungeons drawn from Sanctuary’s past
- Souls Splinters can be found; they contain the essence of iconic foes and grant powerful unique abilities and other benefits
- New unique items from past games return
- New battle pass with additional rewards and currency that can now be carried over from past seasons
