Since the Maalum setting has several idiosyncracies, most classes will need adjustment to fit in the setting. These adjustments will range from somewhat involved to severe. Some guidelines on such adjustments are given here, consult with your GM for further details on the applicability of class features in the setting.

Focus Both base classes and prestige classes in the setting are more focused on their role than the Core base classes. The adventurers of the setting are specialists, instead of generalists.

Alignment Removal If the class has a lot of alignment-related class features, it might not be a good fit for the setting. See Alignment Adjustments for further details.

No Negative/Positive Planes Channel Energy is not a standard feature of cleric-like classes. The ability to channel energy freely in this manner is rare, and called an 'Energy Conduit', if a class has this option, and invokes different energies.

Divine Magic is different Cleric-like classes never need a Divine Focus, and any spell with the Divine Focus components no longer requires this component.
