Serpentine Precision

The cold logic of the Yuan-ti is legendary.  This can be harnessed into a vicious mindset that lends almost unnatural accuracy to attacks that rely on precision rather than brute force. You gain the following benefits when you strike like the serpents you emulate:

• Increase your Dexterity, Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• Whenever you have advantage on an attack roll using Dexterity, Intelligence, Wisdom, or Charisma, you can reroll one of the dice once.
