The Void

A sphere of void appears where the spell is targeted. This creates a 20ft radius sphere of nothingness. Everything inside the spell area is silenced, deafened and blinded while it is inside the sphere. Additionally everything inside the sphere must make a wisdom saving throw or suffer insanity for 1 min and take 8d12 damage.(No insanity and half as much damage on a successful save). You can repeat the save at the end of your turn to end the insanity.
