Wall of Light

Area 
Creates a curtain of light around an area. The wall is four yards high, but may be made higher; simply scale the cost as the height (double for 8 yards high, triple for 12 yards high and so on). 
The only thing it blocks is vision, both ways. It has no effect on spells, beings, sounds, etc. Bright Vision allows one to see through the wall.

Duration: 1 minute. 
Base cost: 1 to 3 to cast. Same cost to maintain. The Wall’s glow depends on the energy put into its base cost, as per Continual Light. 
Prerequisite: Continual Light.

Item

• (a) Staff, wand, or jewelry.  
  Energy cost to create: 200.
• (b) A Wall of Light may be made permanent at an energy cost of 100 times normal.
