Dive straight into Diablo 4's Lord of Hatred campaign without finishing prior chapters

After purchasing the Lord of Hatred expansion, you can start its campaign immediately by choosing it when you begin Diablo 4 with a new character on the Eternal/Seasonal Realm or an existing Eternal Realm character. You’ll head to the Skovos Isles to begin the new content, and while playing through the base game and Vessel of Hatred is recommended for context, it isn’t required to access the Lord of Hatred campaign.
