Blizzard restores immunity sphere in Diablo 4, nerfs two farm methods

Blizzard released a hotfix for Diablo 4 on 28 July 2026 that reintroduced the “immunity sphere” at the end of pit runs. The change was omitted from the German patch notes but appears in the English version, prompting excitement on Reddit and among German players who praised the return of the feature that prevents harmful end‑run effects.

The same hotfix also nerfed two popular farming methods: the gemstone‑and‑gold grind and the large shelter‑key exploit. A bug that allowed players to loot the season‑boss reward in the Blood‑Sole chamber via group‑finder hopping was fixed, reducing the availability of large shelter keys. Players must now adjust their end‑game farming routes, as the undocumented adjustments demonstrate that Blizzard’s updates can affect gameplay outside the official notes.
