Fright-Fueled

Your nervous tick developed into an almost supernatural impulse, sharpening your reflexes and swiftness. You gain the following benefits:
Ability Score Increase. Increase your Dexterity score by 1, to a maximum of 20. 
Adrenaline Rush. While bloodied, you can take the Dash or Disengage action as a bonus action.
Uneasiness. At any point in or before combat, when you are last in initiative order, you can re-roll your initiative roll. Once you've used this feature, you can't use it again until you finish a short or long rest.
