Diablo 4 Rebirth & War Plans: Carry Into Season 15

Diablo 4‘s Rebirth system, per Blizzard’s official Season of Hell’s Legacy overview, lets you convert an existing Eternal character into a fresh Seasonal one instead of rolling a new hero every three months, and Shared War Plans lets that character’s reputation grind help your other saves instead of starting from zero each time, per the same overview. Both features shipped as permanent account systems in patch 3.2.1 alongside Season 15, Season of Hell’s Legacy, which went live on September 15, 2026. This guide walks through exactly what Rebirth keeps, what it destroys, how the War Plans partitions work, and the one Hardcore rule that decides whether a dead character’s reputation survives into Eternal.

Rebirth converts a character from the Eternal realm into the Seasonal realm, transferring it to Season 15 and resetting its level back to 1 . Instead of creating a brand-new Seasonal character from scratch, you pick an existing Eternal character to continue its story for the season . Blizzard also tracks a running tally of hours played across every Rebirth that character goes through, so the time cost of repeated Rebirths is at least visible on the character sheet even without a published average .

The Rebirth conversion sits alongside the rest of Season 15’s launch package — the Prime Evil Soul Splinters, the returning Legacy Uniques, and the new Horadric Cube reroll recipes all shipped in the same 3.2.1 build. If you’re still deciding which of the season’s systems to touch first, the Season 15 Splinters of Evil guide covers the reputation-and-power layer Rebirth doesn’t touch.

If the character isn’t empty, the game simply won’t let the conversion happen — this is a hard block, not a suggestion . Readers coming from an older character who also want the broader pre-season housekeeping — stash space, Season Journey resets, and so on — can check the Season 15 prep checklist for the rest of that list.

Shared War Plans is the other permanent system arriving with Season of Hell’s Legacy. Reputation points earned by one character now carry over to any alt on the same account that matches that character across three separate categories . Each character still keeps its own planner for spending those shared points, similar to how shared skill points or Paragon points already work, so sharing progress doesn’t force every alt into the same build .

Blizzard’s own example makes the boundary concrete: a Seasonal Non-Hardcore Non-SSF character shares War Plans progress with another Seasonal Non-Hardcore Non-SSF character, but does not share with a Seasonal Non-Hardcore SSF character, because the ruleset partition doesn’t match .

For anyone returning to characters that were active before the season changeover, War Plans progress from Season 14 characters carried over to Eternal when the season changed on September 15 . All accumulated reputation points earned on characters within the same partition add together into the corresponding Eternal characters, rather than replacing one another .

Hardcore introduces one condition that changes the plan above. Only the War Plans progress of characters that are living at the end of a season transfers — a dead Hardcore character’s accumulated points are not picked up at the changeover .

If your Hardcore character survives the season

Nothing extra to do. A living Hardcore character’s War Plans points transfer to Eternal on their own at season end, the same way Season 14’s did on September 15 .

If your Hardcore character is already dead

From Season 15 onward, moving a dead Hardcore character’s War Plans progress into Eternal requires one other living Hardcore character in that same partition to go through the seasonal changeover — Blizzard states plainly, “It can even be a level 1 ‘storage’ Hardcore character” . Once that living character moves to Eternal, it deposits the accumulated points into the account’s Eternal Hardcore War Plans progress .

A few practical questions aren’t answered in the official overview or the 3.2.1 patch notes: how many times a single character can use Rebirth per season, whether Paragon points, Paragon boards, or Renown carry over with the conversion, whether a Rebirthed character can be converted back to Eternal before the season ends, and whether the level 1 restart comes with any catch-up XP mechanic . A couple of community guides have filled in guesses here — one speculates Blizzard may cap Rebirths per season, and another states outright that Paragon points do not carry over — but neither claim comes from Blizzard’s own text, so treat them as unconfirmed rather than settled . Whatever the answer turns out to be, the level 1 restart means walking back through the leveling arc that gets a character to endgame Paragon progression, the same climb covered in the guide to where power comes from after level 70.
