Bloodborne

This detects the immediate intensions (either hostile or friendly) of an individual based on the whether or not the individual is bleeding. This knowledge is gained from your beast-like sense of smell by the target's exposed blood. Similarly, if the target is below 50% health and fails a CON save, you now gain the ability to know the targets immediate constitution based off the amount of blood dripping out the body. The detection ends once the wounds heal, are well covered or the target is beyond range.
