A big list of available Perks that you can buy to progress your characters, split into paths. Each World has a separate list.
It’s recommended that you browse the available paths’ descriptions to progress in and pick perks fitting for your character’s roleplaying.
A traveling merchant, for example, can advance in the Social and Intellect Paths, for good prices, connections, navigation and market study. Whereas a traveling con artist might favor more Finesse perks for quick escapes.
