In Atlas Skills, Pick Waystone Rarity & Drop Chance First

Once you progress into the Atlas and complete your first 10 Tier 1 or higher Waystones, Doryani will give you a book that grants 2x Atlas Passive Skill Points. This Passive Skill Tree is separate from the regular PoE 2 Skill Tree and only applies to Path of exile currency maps in the Atlas.

The nodes on the Atlas Skill Tree affect mapping in a variety of ways, but there are two that should be prioritized first: Waystone Rarity, and Waystone Drop Chance. There are a few Passive Skill Nodes to the right and bottom-right of the starting point in the Atlas Passive tree that buff the Rarity and Drop Chance of Waystones.

Pick up as many of these Atlas Passive Skills as you can in the early stages of the endgame to make the process of acquiring more Waystones, and acquiring useful Waystones, much more rewarding. Later on, other Atlas Passive Skill nodes can be useful for different situations or preferences, but the Rarity and Drop Chance nodes are practically required to POE currency for sale map efficiently.
