Your superior training allows for you to keep in-tune with your
surroundings:
• You are immune to being deafened or blinded.
• As a bonus action, you focus your attention on a creature
of your choice, that you can see within 120 feet of you.
Until the start of your next turn the target can’t become
hidden from you even if becomes invisible. You can use this
feature a number of times equal to your Wisdom modifier
(minimum of once) and regain all expended uses when you
complete a long rest.
