LPJ Design has released Debatable Actions, a sourcebook to resolve verbal conflicts for the Pathfinder RPG.
This 23 page PDF, written by Louise Porter Jr. and Jonathan Palmer, introduces three systems to rule debates that are central to the plot of a campaign.
There are also simpler debate rules to resolve 'sidetrack' discussions, aside from the new feats, skills use, spells and wondrous magic items to give your characters an edge on the debate.
The sourcebook also comes with a 36-card deck for use to enhance gameplay.
Debatable Actions is now available at RPGNow and DriveThru RPG for $4.99.
