Tips & Tricks for PoE 3.23 Passive Skill Tree:

Use the search bar to find passive bonuses related to specific damage types or defenses. This simplifies targeting specific nodes.

Zoom in and out of the tree using the mouse wheel or slider for better navigation and focus.

Be cautious of "dangerous" keystones like Chaos Innoculation and Blood Magic, as they can drastically alter your character's abilities.

Recognize the attributes associated with regions of the tree (red for strength/melee/armor, green for dexterity/ranged/evasion, blue for intelligence/spells/energy shield) to understand the layout better.

Consider following a build guide to minimize wasted points and avoid unnecessary respeccing later on.

Note that notable passive skills at the ends of clusters unlock mastery bonuses in the middle, which are shared across the tree.

Utilize jewel sockets to socket jewels for additional bonuses once the socket node is taken.
