You have Darkvision with a range of 60 feet.

Shifting (Swiftstride)

As a Bonus Action, you can shape-shift to assume a more bestial appearance. This transformation lasts for 1 minute or until you revert to your normal appearance as a Bonus Action. When you shift, you gain Temporary Hit Points equal to 2 times your Proficiency. You can shift a number of times equal to your Proficiency, and you regain all expended uses when you finish a Long Rest.

While you are shifted, your Speed increases by 10 feet. Additionally, you can move up to 10 feet as a Reaction when a creature ends its turn within 5 feet of you. This reactive movement doesn't provoke Opportunity Attacks.
