Another idea! I was reading a master list of homebrewed martial disciplines over on the Homebrew Design section of the forums, and I saw this logically devastating discipline. Way back when I started this setting, I wanted to incorporate political intrigue, and I this discipline gave me an idea.

In an attempt to make use of the magic mechanics of the Warrior, Rogue, and Mage--and to provide non-magic options in the game--I think I'd like to come up with a few "spells" that are flavored as rhetoric, and can be used to persuade and maneuver in a court setting. The character that would get the most use out of these spells would be some sort of court official, but they could just as easily be used by a witty combatant or a trickster character.

I don't have any specific examples at the moment, but I'll be thinking about this for the next few days. I'll post my ideas here.
