Ok I was double targeting two clicks one was fine but my ? Comes into play when I was shooting a piece on higher elevation but blocking terrain on the ground stopped his sight. I disagreed being it is a outdoor map I said blocking doesn't exist on higher elevation only on a indoor map it does. So who was correct

If the line of fire crosses blocking terrain, and the character on level 1 is not a giant or colossal, line of fire is blocked to a character on the rim of level 2.
X = character, Y= character, B = blocking, 1's & 2's = elevation level

1 1 1 1 1 2 2
1 X 1 B 1 Y 2
1 1 1 1 1 2 2

From the 2011 Rulebook:

Ok. What about a similar scenario:

Level 1 standard character to level 1 Giant or Colossal, with level 1 blocking terrain in the way.

1 1 1 B 1 1 1 1
1 S 1 B 1 1 G 1
1 1 1 B 1 1 1 1

Kind of like that. S = Standard, B = Blocking, G = Giant.

@ Roderic
in your case Line of Fire (LoF) is Blocked too,because the grounded character is on the same elevation as the blocking terrain.
If you had a standard character on elevation level 2 a blacking on level 1 and a Giant Colossal on level 1,then the LoF would be clear

Many thanks!
