Ghost Mist

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.
