Detection

Send out a light pulse of weave. After it returns the information of the amount and approximate location of all creatures within a 30 ft sphere is telegraphed into your mind for a moment. If an affected creature has a wisdom score above 16 they must roll a wisdom saving throw and on a failed save don't realize they were noticed, on a successful save they realize someone detected them or they feel as if they are being watched. 

When cast at higher levels: For every level higher this spell is cast add 20 ft to the range of the spell.
