PFS StandardMultifarious Muse Feat 2

Source Player Core pg. 101

Your muse doesn’t fall into a single label. Choose a type of muse other than that of your own. You gain a 1st-level feat that requires that muse, and your muse is now also a muse of that type, allowing you to take feats with the other muse as a prerequisite. You don’t gain any of the other effects of the muse you chose.

Special You can take this feat multiple times. Each time you do, you must choose a different type of muse other than that of your own.
