The Light-spell might be all right, but sometimes, things have to be illuminated even more. Then this spell comes in handy. Once spoken, a light as bright as a second sun will scare away the shadows, leaving no place for creatures of darkness to hide.
Vas Lor conjures a great light. This light is equivalent to In Lor's in quality and range, but Vas Lor lasts longer. Its endurance comes from mandrake root. Mix the prepared root with sulphurous ash and proceed as if making In Lor.
