How do I use the Convincing persona feat without dual identity or masked persona

Question

People seem almost willfully ignorant of the connection between your masked persona and your real identity. Prerequisite(s): Bluff 5 ranks, Perform (act) 5 ranks, or dual identity class feature. Benefit(s): Your dual identity is never considered publicly compromised barring some massive, public unmasking, allowing you to benefit from your dual identity or masked persona regardless of how many people know your true identity. You gain a +5 circumstance bonus on Bluff skill checks to convince people your masked persona and your true identity are entirely different people, and on Disguise checks to maintain your masked persona.

The feat reads as such, from that I can’t see anything that can be gained from the ability without that class feature. Am I wrong on that. Maybe the “or” is a typo and they meant “and” instead?

I took it by mistake on a previous character not realizing it went with a class feature. Then again that character was an optimization nightmare and I ended up just rerolling first chance I got. So doesn’t really matter now. I might make a vigilante some day once I get over my obsession with casters.

Answer 1

The feat Convincing Persona is useful not only to those who possess the extraordinary ability dual identity (a level 1 vigilante class feature) but also to those who've undergone the ritual of creating a masked persona, an "option available to all classes."

However, the Convincing Persona feat is pretty much useless if a creature doesn't possess the extraordinary ability dual identity and hasn't undergone the masked persona ritual, but Pathfinder has many feats like this. (For example, the feat Quicken Spell can be taken by a creature that can't cast spells.)

A creature that meets the Convincing Persona feat's prerequisites yet possesses neither a dual identity nor a masked persona may take the feat in anticipation of realizing its benefit later, for example.
