Blinding light

A blinding magical light spreads from a point you choose within range to fill a 15ft radius sphere or 40ft cone for the duration. The light spreads around corners if it's a sphere but not with a cone. There is bright light for another 40ft and dim light for another 40ft. 

If the point you choose is on an object you are holding or one that isn't being worn or carried, the light emanates from the object and moves with it. Completely covering the source of the light with an opaque object, such as a bowl or a helm, blocks the light.

Anyone who is in the 15ft radius is considered blinded while in the sphere, they also need to make a dexterity saving throw to cover there eyes against your spell save dc, if they fail there save they will still be blinded after leaving the area of the spell. After which a creature can make constitution saving throws at the end of there turn to regain there vision. If the cone is directly behind a creature or there eyes are covered they are not effected. Blindsight, true sight, and tremorsense are unaffected by the spells affects.
