"Return of Evil" takes players on a journey through Sanctuary as ancient evils resurface, drawing inspiration from Diablo II: Lord of Destruction and Diablo Immortal. The treacherous lands, such as the desolate wastelands of Aranoch and the corrupted jungles of Kurast, become arenas of conflict. Players confront formidable adversaries like Baal, Mephisto, and Skarn, Lord of Damnation. Heroes must delve into forbidden tombs, uncover lost relics, and harness the power of the Nephalem to prevent the resurgence of ultimate darkness.
