Necromancer — Skill Tree

The shape of a class's power — every node of its skill tree set where the game places it, joined as the game joins them.

This is a map of the tree's shape, not a point-by-point planner. Nodes are marked by kind; the skill nodes of the six core classes are named, while Spiritborn and Warlock — whose trees are built differently — are shown by shape alone.

Tree layout datamined from the community DiabloTools/d4data (game build 3.1.3.73224). An unofficial reference; the live game is the final word.
