skilltree05

This project is a single-file HTML viewer for the passive skill tree in Path of Exile 2, a complex action role-playing game. The passive skill tree is a large map of character upgrades that players navigate to shape how their character plays. Version 0.5.0 of the game has over 5,000 nodes on that tree, and this tool lets you explore all of them without installing anything.

To use it, you download one HTML file and open it in any web browser. There is no server to set up and no software to install. Once open, you can pan across the tree and zoom in and out, search for nodes by name or by what they do, and jump directly to the section of the tree that belongs to a specific character class or subclass.

The viewer highlights three groups of nodes in different colors: nodes that are brand new in version 0.5, nodes whose numerical values changed compared to version 0.4, and nodes that only the Druid character ascending into the Oracle subclass can access. When you hover over a changed node, the tooltip shows the old stat crossed out next to the new one, so you can see exactly what shifted between the two versions.

The data behind the viewer comes from official exports published by Grinding Gear Games, the developer of Path of Exile 2. The author pulled in both the 0.4.0 and 0.5.0 exports to produce the change comparisons. The entire thing is self-contained in that single HTML file, which means you can save it locally and use it offline without any dependencies.
