There’s a new kind of challenge in Diablo III with the advent of Set Dungeons, specific challenges with pre-determined sets. The latest entry on the official site explains how these set dungeons came to be, with the overall design intent being similar to the goal behind the game’s season progression: a new way to play and experience the game for players eager for a new challenge.
Senior game designer Alex Sulman came up with the basic idea for Set Dungeons during a team-wide brainstorming session, with the whole Diablo III team trying out new passion projects and seeing how they worked in the game. The original intent was to make them solo-only experiences, but ultimately having them be available for multiple players provided a better overall experience, even though the dungeons are possible to complete while solo. If you’re curious about the steps between the concept and the final execution, give the full entry a read-through.
