World map size

Players can expect the thrill of finding chests while exploring. Some, like Silent Chests, are locked with keys.
Local Events occur randomly across Sanctuary and vary in difficulty. Random players may join in to help.

A huge, diverse world to explore
The Diablo 4 map is 10-20 times larger than past Diablo games, dotted with hundreds of interesting destinations to explore, including Dungeons, Strongholds, and towns. Mounts and Waypoints are vital in quickly traversing the huge world.
See other players in the Open World
Sanctuary is now an Open World, meaning that players can chance upon dozens of other players (mostly in larger towns, like Kyovashad, but sometimes while out exploring). Random players can join forces to complete Events and take down massive World Bosses for big rewards.
Open World map is fixed
Although the layout of the Open World is fixed (i.e., landmarks are in the same spot each time a player visits), players can expect lots of serendipitous occurrences, like random Events, Helltide areas, and Elite Monster sightings.
Exploration rewarded with Renown system
Blizzard created the Renown system to encourage players to explore the off the beaten path areas of the map. Players are given Renown Points for discovering new areas, completing Dungeons and Side Quests, and more. The rewards are significant, like extra Skill Points and Paragon Points.
