Echoes of Location

Use the ancient draconic magic of the thu'um trapped within your blood and mutated by Morgana. 

When you use this ability you whisper a sonar cone 60 foot in a specific direction allowing you to detect the location and size of any tangible creatures caught within the cone. This ability can only be heard by creature with advanced hearing. (Creatures with advanced hearing roll at disadvantage to perceive the origin of this ability.) 

This ability can be used a number of times equal to your proficiency bonus
