Prerequisite(s) legendary in Diplomacy
You can negotiate incredibly quickly in adverse situations. You attempt to Make an Impression and then Request your opponent cease their current activity and engage in negotiations. You take a -5 penalty to your Diplomacy check. The GM sets the DC of the Request based on the circumstances—it's generally at least a very hard DC of the creature's level. Some creatures might simply refuse, and even those who agree to parley might ultimately find your arguments lacking and return to violence.
