Auxiliary Levels

You have the option of gaining an auxiliary level whenever you advance in level after 1st, instead of gaining a level in your current class. An auxiliary level follows the general rules for multiclassing and might require that you meet a prerequisite before taking it. Sometimes these prerequisites are class features which you must gain from a base class, and some are narrative prerequisites that you must work with the GM to accomplish before taking the class.

HIT POINTS AND HIT DICE

Like any base class, auxiliary levels grant you additional hit points and Hit Dice. You add together the Hit Dice granted by all your auxiliary classes to determine your pool of Hit Dice.

PROFICIENCIES AND LANGUAGES

An auxiliary level specifies if it grants additional proficiencies or languages when you take it. Your proficiency bonus is always based on your total character level, not your level in a particular class.
