Blood sense

You can feel the pulse of living creatures nearby.

As a bonus action, you can open your awareness for 1 minute. For the duration, you know the location of any creature with blood within 30 feet of you that isn’t behind total cover, even if it is invisible or hidden. This doesn’t reveal its identity, only its location and whether it appears healthy, injured, or near death.

You can use this feature a number of times equal to your proficiency bonus per long rest.
