Distracting performance

You begin a performance imbued with magic.

You must roll a performance check and all creatures of your choice that can see and hear you must make a wisdom saving throw against your check. On a failed save all creatures that are not affected by the spell have advantage on skill checks against the target until the spell ends.

Upon leaving the area of the spell the effect will end but if an affected creatures leaves and then returns  to the area the effect will be reapplied

If a creature uses detect magic the spell will be revealed to the being but otherwise creatures will not realize that magic was involved after the spell ends.
