A Battledancer Swashbuckler can have Fascinating Performance and Focused Fascination at level 1. In short, Fascinating Performance allows them to Fascinate a target when they make a Perform check, and Focused Fascination makes it so they don't need to critically succeed to apply this effect on combat.
However, the Fascinate condition "ends if a creature uses hostile actions against you or any of your allies." In combat, this will be happening more or less constantly, so it seems like the Fascinate status won't last very long, possibly just a single character's turn.
Am I missing something, or will the condition applied by Focused Fascination only be relevant in very rare circumstances? For context, I'm asking because a player of mine expressed frustration at how limited the use of this feat is, and I'm trying to understand if the feat is better than I think or not.
