Diablo 4 Season 5 Infernal Hordes started on August 6 and will end on October 8. It is accompanied by Patch 1.5.0, which adds Infernal Hordes endgame activity, 50 new Uniques, and various quality-of-life changes. A new season signifies a clean slate for those eager to conquer their seasonal battle pass and claim its rewards, but this patch has many benefits for Eternal Realm players too.
