Sourcebook: Debateable Actions

From publisher blurb:

Debatable Actions brings some of the tactical depth of 5e martial combat into the realm of verbal exchanges. It’s perfect for situations where you want the act of persuasion to be center stage and to involve more than a simple skill check. These rules are designed to encourage deeper role-playing and help GMs create intense verbal sparring matches between players and NPCs outside of combat. Even players who aren’t really into debates or social encounters can enjoy the strategic gameplay of verbal combat.
