Ball of Confusion

As the spell is cast the shards of broken ceramic begins to spin in a multicolored ball flashing lights.  As it is cast the ball hovers upon the target and ethereal bass and drum beats take up a very disco/techno beat for a 20 foot sphere.  Those within the sphere must beat the casters Spell Save DC or become incapacitated for 1d4 rounds.  Those beating the Spell casting DC become incapacitated until the start of their next turn. 

Levels above 3rd level increase 1d4 per level for incapacitation.
