Chortling Laughter

you hear this weird mocking laughter coming from somewhere, but where is it? 
when Chortling Laughter is casted all creatures within range must make a Wisdom saving throw to see if they get distracted. And the caster must role a charisma (deception) check 
if the saving throw is failed every turn the effected must make a investigation check, costing them their action, of effected rolls higher than the caster’s previously rolled deception check. 
When beating the deception roll the effected is no longer affected by the spell. 
when rolling lower then the caster, the effected must do the same thing every turn until it is dispelled.
