Adventure Mode is available to all Seasonal Diablo 3: Reaper of Souls characters by default. If you don't have a character yet, consider creating a Seasonal one. After season concludes, you will get access to Adventure Mode.
To unlock Adventure Mode for non-Seasonal characters you need to finish the last Campaign quest on any difficulty.
- Ask a friend or a random player to help you defeat Malthael. Your friend should create a Campaign game and select Act V quest 8 (Angel of Death) part 3 (Malthael).
- Defeat Malthael and enjoy Adventure Mode!
