Blocking terrain represents areas and objects on
the map with the potential to completely impede
a character’s movement and line of fire. Any line
of fire or path of movement that crosses blocking
terrain is labeled a “blocked” line of fire or path of
movement, the movement cannot happen and
the line of fire is not able to be drawn through this
terrain. • Movement: Blocking terrain prevents movement.
Characters can’t move into or through blocking
terrain. • Line of Fire: Blocking terrain prevents a line of
fire from being drawn between two squares.
Any line of fire crossing a square of blocking
terrain is blocked (except for a line of fire
between two elevated characters that crosses
grounded blocking terrain).
