Pax syringe

Pax syringe is an ammunition type in Fallout 4.

Characteristics
The Pax syringe is a small little syringe akin to that of a tranq dart. The Pax syringe is not actually considered ammunition instead it is located under aid and has weight (Albietly a very low amount of weight).

The syringe has a chance to make the target non-hostile for 30 seconds. While it says "chance", this appears to always work.

In addition to the benefits of having one less enemy, albeit temporarily, non-hostility means the enemy won't be trying to search for you if stealthed, and they can be pickpocketed (useful for e.g. stealing the fusion core out of an enemy in power armor, forcing them to exit).

Behind the scenes

 * The name and effects of this syringe are a reference to Serenity. The G23 Paxilon Hydrochlorate called the Pax was intended to weed out aggression and worked over well causing most to lay down and die while a small percent became violently insane reavers.
