Where does he get those Wonderful Toys?

Characters with this feat must own a palm pistol. This feat places your palm pistol inside a spring loaded wrist holster. This provides two benefits.

Once per Short Rest, you may activate your spring loaded holster, ignoring the first range increment on your Palm Pistol (Pistol must be Loaded). On a success, add 1d4 Bludgeoning damage to Palm Pistol damage, and the target is pushed 5ft in a random direction. On a misfire you, the target, and everything within 5ft of the target must make a Dexterity Saving Throw or suffer 1d8 Fire damage. 

Once per Long Rest, you may trigger a loaded black powder charge on the outside of your wrist holster adding extra oomph to your unarmed strike. On a successful hit, the target must make a Constitution Saving Throw against a DC of: 8 + your Proficiency Bonus + plus your Dexterity or Strength bonus (your choice).  On a fail, the target falls Asleep until D100 minutes, the target takes damage, or someone uses an action to shake or slap the sleeper awake. Undead and characters that are immune to the Charm effect are immune to this feat.
