Key Changes in 3.28
- Multiple Modes: Breach can now be played in different "modes" (e.g., Unstable Breach or Hive farming), allowing you to tailor your strategy.
- New Clusters: Several new Breach clusters have been added to the Atlas Tree.
- Reward Rework: The Breach reward "tree" no longer generates rare weapons or quivers but can still produce Foulborn unique weapons.
- Fortress Mechanic: Accessing the "Fortress" now requires investment through specific Atlas nodes or scarabs; it is no longer a guaranteed part of the encounter.
- Investment Cost: Unlike in 3.27, Breach is no longer "free." To make it profitable, you must invest points into the Atlas tree and use Breach Scarabs.
