Otherworldly Artefacts is another new Breach-related Notable Passive on the Atlas Tree.
Otherworldly Artefacts
The Otherworldly Artefacts Notable Atlas Passive no longer has "Rare Breach Monsters in your Maps have 0.5% chance to drop an additional Breach Blessing". Instead, it now has "Breaches in your Maps have 20% increased Monster density". It also now causes Breach Monsters in your Maps to have 50% increased chance to drop a Breach Unique item (previously 100%).
