So I'm a little confused about the prismatic wall spell, and I wanted to check some things so I don't use it wrong. It says 4 ft. wide per caster level, and 2 ft. tall, but no length. AM I to assume the wall takes up a 5 foot square, and by width it really means length?
Also I says if it is cast in a square a creature resides the spell is wasted, but will to work around objects, like a bridge? I think it will, but I want to make sure.
The width is the length. The wall has no "width" (as in thickness) as it merely a magical barrier.
OK, so it basically goes on the line between the squares right?
