Question

What is the Performance DC for feats with the "Combat Performance" tags?

Example: Dramatic Display feat

What is the Performance DC that you add the +2 to skill check from the feat that gives you a +2 to attack rolls till the end of your next turn?

Answer 1

Performance feats are specifically for performance combat, e.g. sparring, an exhibition match, gladiatorial combat, etc. In such a fight, you get an option to use a swift action to make a “performance [combat] check” to hype up the crowd. The effects and DCs for doing so are part of the performance combat rules. Performance feats only apply to such fights, and often revolve around this check, making it do more or giving alternate options to just amping up the crowd.

In particular, Dramatic Display says that when you make that performance check, you get +2 on that check as well as some other bonuses for the rest of the round. It doesn’t care if you succeed or not, and you’re not making a separate check just for Dramatic Display. You’re making a performance check for some other reason, as described in the performance combat rules and/or some other performance feat, using the DC that’s appropriate for the check you’re making, and then you’re getting extra bonuses above and beyond whatever the original effect of the check was.

Since these feats only apply during performance combat, they’re worthless for most Pathfinder characters. Only in highly themed games where every combat is in front of a crowd are they worth even considering. Even in such a game, Dramatic Display is a mediocre feat.
