Jenkin’s Tendons

Your musculature has been adapted to allow for blinding bursts of movement - though limits have been put in place to prevent damage from overuse. When you move on your turn in combat, 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. You may use this a number of times equal to your Proficiency bonus per long rest.
