Wall of Light

R: 50 ft; T: area; D: 10 minutes / permanent

You conjure a hemisphere [dice]x5 ft in diameter or [dice] 10x10 ft contiguous panels. The wall is intangible, but you control what either side shows, such as inky darkness, 30 ft bright light, mirror surface, transparency, or a simple texture. These can be changed at any time.

At 4 [dice], the duration is permanent.
