A square with a red line running through it with an
elevation of a lower level sharing an edge with it
is considered “the rim.” Characters on the lower
elevation are not adjacent to the rim any more than
they are adjacent to a character occupying the
square that the rim borders. A line of fire between
characters on different elevations is blocked by:
• Blocking terrain on the same elevation as
the character on the lower elevation.
• Elevated terrain of any level higher than the
level occupied by the character on the lower
elevation, except the square occupied by
the character on the higher elevation.
•Giant or Colossal characters.
A line of fire between characters on different
elevations is not affected by hindering terrain, regular or
tiny characters, except for the square the target
