You are talented at surprising people and getting in and out of trouble. Once per day you can add your Dexterity modifier to your initiative.  You also gain a permanent +1 to your Dexterity score. Additionally, you gain the ability to male a tactical roll and gain an additional 5ft of movement speed if a successful Acrobatics check DC 15 is made, this can be used once per short rest.
