A new map is open with the patch, the Ruins of Sescheron. This icy wasteland not only gives more fodder for your mighty hand of destruction but also adds a story surrounding a mystery of the absent barbarians who used to live there.
Players will want to venture into the Ruins since it’s the only place in the game to obtain Kanai’s Cube, a sort of successor to Diablo II’s Horadric Cube. Kanai’s Cube allows for further item customization and ways to extract and forge legendaries.
Patch 2.3.0 also contains a new season journey which will kick in when Season 4 begins and updates to Diablo III’s adventure mode.
