Good day!  I have a situation with my gaming group regarding something our 5th level shade warlock did.  The situation is that the warlock invoked darkness (creating a 20' radius area of shadowy illumination as stated by the spell).  He then wishes  to control the light as per his Shade abilities (dimming it a bit further by 50%).  Any thoughts on how this should be treated?
Thanks
Mike
