Beholder Blessed

Legend said that your ancestors had worked with Beholders in the past and had been touched by their foul magic. As a boon... or perhaps a curse, you were born with an extra magical eye. 

You gain +2 in Perception and can cast Antimagic Field (target Self only) with a range of 40 feet, once per day without a spell slot, and you regain the ability to cast it that way when you finish a Long Rest. When you cast a spell in this way, it requires no spell components.
