You don't like conflict and know just the way to avoid it. When you take a hit off your pipe, as a bonus action, you blow a calming smoke out affecting all creatures in a 20 ft area around you.

Affected creatures must make CON saving throw or be stunned until the end of their next turn. 

Alternatively, you can choose to only affect friendly creatures and give them 1d4 bonus to an initiative roll, attack roll, ability check or saving throw until the end of the their next turn
