AKA the Diplomatic Rifle. This long firearm is ornate but not ostentatious, powerful but not gratuitous, and in all ways quite reasonable.
Level 19+ Rare
Weapon: Rifled Carbine
Critical: +1d6 thunder damage per plus, and the target takes a -2 penalty to attacks until the end of its next turn.
Property You gain a +5 item bonus to Intimidate checks.
Property If you will it, you can project your voice sufficiently to be heard across a crowd out to a distance of 500 feet.
Power (Encounter) Minor action.
You fire a shot in a direction that won’t hurt anyone. Make an Intimidate check. If your check beats the Will defense of every hostile creature within 500 feet, combat pauses so you can talk, treat the injured, or attend to other pressing matters. If any creature (even an ally) re-initiates hostilities before one minute has passed, the bullet you fired returns and strikes that creature as if you had rolled a natural 20 on a basic attack. The bullet strikes after the triggering hostile action has resolved, and requires no action.
