Like a bloodhound, you can sniff out the injured. As a bonus action, you can mark a creature within 5 feet of you with hit points below their maximum. For the next hour, you have advantage in Wisdom (Survival) and (Perception) checks to track and find the creature. Additionally, as a bonus action, you may make a Wisdom (Perception) check on a creature and know whether it is above or below half of its maximum hit points.
