Diplomatic Firearm +2

Ranged weapon (any firearm with an ammunition clip)

This firearm was first crafted by the Drakran gunsmith, eschatologist, and assassin Kvarti Gorbatiy. Ornate but not ostentatious, powerful but not gratuitous, it is, in all ways, quite reasonable. Its stock is malice beast bone, and its barrel is simple steel. 

You have a bonus to attack and damage rolls made with this magic weapon. The bonus is determined by the weapon’s rarity.

As a bonus action, you can fire a bullet into empty air, startling enemies that are actively combating you and your allies, provided that the enemies can hear the gunshot. All startled enemies must collectively and subconsciously nominate a leader among them. If the leader fails a Wisdom saving throw (DC 15), you create a detente for 1 minute, which you can use to speak, initiate diplomatic action, tend to the wounded, or perform some other activity. Depending on the circumstances, it is possible that hostilities may simply resume after the minute.

During this detente, if a creature that is part of the detente, even an ally, takes a hostile action, the bullet returns and strikes that creature. After the hostile action, the creature takes 10d10 piercing damage.

Once you have attempted to quell hostilities using this weapon, you cannot do so again until the next dawn.
