In Path of Exile 3.28 (Mirage League), the Atlas Passive Tree for Blight has been reworked to focus more on juicing final rewards and less on simply spawning additional monsters.

Recommended 3.28 Blight Farming Strategy
The "Invigoration" or "magic monster" farm from previous leagues was heavily nerfed and is likely no longer viable. Instead, focus on "Normal" Blight farming for chest loot:
Essential Nodes: Prioritize all Blight wheels for increased chance of encounters, Oils, and Blighted Maps.
Tower Power: Use the Amber Oil strategy (3x Amber Oils on Blighted Maps) to reduce tower costs by 75%, allowing any build to clear them with minimal gear.
Map Selection: Toxic Sewer remains the top choice for forcing tight, efficient Blight lanes that are easier to defend.
Atlas Links: You can find updated 3.28 Atlas planners on community tools like PoePlanner or Path of Pathing.
