Howl of Pandemonium

Casting time: 1 action
Range: 30 ft radius or 60 ft cone
Components: V, S, M
Duration: Concentration (special)

You summon the screaming winds of Pandemonium thru your body into a numbing wail effecting all creatures within either a 30 ft radius or a 60 ft long cone (your choice). The spell lasts for however long you concentrate on it up to a maximum of 1 round per level, and for an equal amount of time after you stop concentrating. All creatures within its area of effect are deafened, cannot communicate by any means, suffer disadvantage to attacks and saving throws, nonmagical ranged weapon attacks and sound-based attacks automatically fail, and creatures trying to approach nearer to you must make a Strength saving throw or be unable to move any closer for that turn. Finally, any creature caught within the winds must make a Wisdom saving throw or be effected as per the Confusion spell.

The material component is a pebble from Pandemonium which must be consumed upon casting.
