Ghost-Mist

Is a spell that has a casting value of 5 and a range
of 6". If successfully cast, pick 1 terrain feature
within range and visible to the caster. Until your
next hero phase, visibility between 2 models is
blocked if a straight line 1mm wide drawn
between the closest points of the 2 models
passes across more than 3" of that terrain feature.
This effect does not block visibility to or from
models with a wounds characteristic of 10 or
more.
