Daring Performer is like getting an extra encounter power. It lets you make your 1/encounter bluff check to gain CA instead of Deft Strike's movement. Useful.
All of the fighting style feats were introduced in different Dragon magazine issues. They're available in the D&D Compendium and the Charater Builder.I didn't know about all of those powers, feats, or whatever they are. Is that all Dragon material?
