Natural Sprinter. The chase is in your blood, they know how to cover ground quickly and maneuver through chaos. Your base walking speed is 40 feet and you make all Acrobatics skill checks relating to running at advantage.
Feline Agility. When you move on your turn, you can double your speed until the end of the turn. Once you use this trait, you can't use it again until you move 0 feet on one of your turns.
Reflexive Pursuit. When an enemy that you can see within 60 feet uses the Dash action, you may use your reaction to move up to your speed toward it. Additionally, if you end this movement within 5 feet of a creature, you may attempt to shove that creature. You may use this trait a number of times equal to your Constitution modifier (minimum 1), and you regain all expended uses when you complete a long rest.
