We are using the base Pathfinder classes and the variants allowed. Please see the house rules page for details. As always, all classes, even those in the books, must be discussed with the DM before final approval is given. There are allowances for almost every class created in all of D&D in the game, not just pathfinder, but understand that not every class and every race are available in every place. e.×. There is only one place in the world that trains Bladesingers.
All classes, even those in the books, as listed, are subject to change based on out of game balance issues, or in game changes based on world events.
Relax, all that is just a disclaimer because sometimes players rock the world boat and serious shit goes down.
