PoE Incursion Atlas Tree 3.28

In Path of Exile 3.28 (Mirage), the Incursion (Alva) Atlas passive tree focus remains on efficiently generating "Double Corruption" temples (Doryani's Institute and Locus of Corruption) for high profit. The 3.28 patch introduced a significant Atlas Rework and the removal of Chisels, which shifted some node locations, though the core Incursion mechanics remain consistent.

Quick Incursion Tips

Priority Rooms: Always prioritize Locus of Corruption (Corruption Chamber tier 3) and Doryani's Institute (Lapidary Lens tier 3) as these sell for the most currency to other players.
Speed Management: Incursion is considered a "fast" mechanic. Pairing it with other fast mechanics like Essence or Shrines is recommended for efficient mapping.
Respecs: If you need to change your tree, you can now use Gold to respec Atlas points through Commander Kirac.
