Outriders: Worldslayer has introduced multiple new progression systems to keep players busy in Expeditions and the new Trial of Tarya Gratar endgame dungeon. One of the first new systems you'll be introduced to is your class' second skill tree, known in-game as your PAX Tree.

Each class in Outriders has access to a second, unique skill tree that provides some build-enabling benefits. While it's smaller than your standard character tree, the choices you make in your PAX Tree can fundamentally make or break a build in higher Apocalypse Tiers. Here is a complete guide to Outriders' PAX Tree system.

What Is A PAX Tree?

Outriders PAX Tree Example

A PAX Tree is a secondary skill tree you unlock during the Worldslayer campaign. Every class in Outriders has access to a unique PAX Tree that branches into two distinct paths. Each node in a PAX Tree is significantly stronger than a typical skill tree node, providing effects on par with Legendary sets and T3 mods.

As strong as these nodes can be, you may only have five nodes allocated in your PAX Tree at a time. Respeccing your PAX Tree can be done at any time for no cost.

Unlocking Your PAX Tree

Outriders Character Cinematic

Your PAX Tree unlocks upon completing the "Trepedition" quest during the Worldslayer campaign. By default, you'll only have access to one PAX Point, acting as this tree's version of skill points. Subsequent PAX Points may be earned by completing the following Worldslayer quests:

  • Pilgrimage
  • Shards
  • Wrath
  • Trial of Tarya Gratar

A maximum of five PAX Points are available in Worldslayer. All of these quests are tied to Worldslayer's main questline and endgame activity, so don't worry about missing any during your playthrough.
