Version history

Version	Changes
3.24.0	The Mycelial Swarm Notable Atlas Passive has been removed, along with the two small Blight Crafting Option Passives in this cluster.
3.20.1	The Blight Atlas Passives that provided your Maps with Blight Encounters a chance to contain an additional Blight Encounter have irreconcilable issues that result in areas with two Blight Encounters failing to generate reliably, so we have replaced these stats. The Mycelial Swarm Notable Atlas Passive now provides "Blight Map Crafting Option is always available" and "50% reduced cost of the Blight Map Crafting Option." [Ruthless-specific This patch note only applies to Ruthless mode and does not affect the main game mode.] The Mycelial Swarm Notable Atlas Passive now provides "Lanes of Blight Encounters in your Maps have 20% chance for an additional Reward Chest".
3.17.0	It is now possible to have multiple Blight Encounters in a single Area through the new Blight Atlas Passive Skills.
