Path of Exile · Passive node
Masteries
A Mastery lets a character select one passive effect from the category associated with an allocated cluster.
How it works
Masteries are available in clusters outside a class’s starting area. The player can allocate a Mastery after allocating that cluster’s Notable through the normal tree route. Each category offers a shared set of effects; after selecting an option, the same option cannot be selected again through another Mastery in that category. A Notable acquired through anointing or Intuitive Leap does not enable a Mastery.
