Bandolier of Barrom

You have a +2 bonus to attack and damage rolls made with this magic weapon.
Madam Barrom was an odd women. Always thought a knife at her back. She found many ways to hide weapons on her person through the years but this bandolier is the perfection of her insanity. Looking like a typical wrist wrap. Bound in fine silks... a slip of the finger can produce a weapon for the wearer as they please.
You must Draw the Needles from the wrist wrap before you can use them. They shatter harmlessly into energy after hitting anything while thrown 

Upon Attunement the needles no longer shatter upon impact. Instead doing Extra damage to the target for every needle lodged in them. Dealing lighting damage is equal to 1 for every needle already in the target as they arc together. The needles still shatter harmlessly upon being pulled from the target which can be done as an action.
However attunement also comes with giving disadvantage on insight checks as the mind dulls on social cues. Not Affecting yourself in anyway but making it hard to read for deeper meaning.

Proficiency with a Dart allows you to add your proficiency bonus to the attack roll for any attack you make with it.
