OK, I hate asking this type of question but I need 100% clarification knowing I am dealing with 2 colossus soon in an IG event.

Outdoor maps, blocking terrain blocks line of fire with the character on the lowest level.

So if we have

xxxCBxxxxZ

where C is a normal click, B is blocking terrain and Z is Ziran, then Ziran can not see C and the same back

If the sititation is

xxCxBxxxxZ

then is it the same? Does that one space in between the click and the blocking change things?

It's all the same elevation.

Just for more clarification, if we have

xxTBxxxxZ

where T is a 350 Thanos, z is ziran but B is for Bob, Agent of Hydra, with the power

Ziran then can see over Bob to Thanos, correct?

Last question, does the fact that a colossus take up so many squared affect the line of fire? Do you draw line of fire to and from the MIDDLE of the squares he is in, or from any square he is on, therefore one square may be blocked but another is not?

Whenever you draw a line through blocking, you're blocked. However, in the case of drawing a line THROUGH Bob, you can. Because you're taller. Only lies drawn TO him are blocked. Like, if a normal sized guy tried to hit the guy behind Bob, and Bob was in the line of fire, he would need to shoot Bob. However, since he can't it's an invalid target so you can't fire.

Blocking terrain blocks LOF to or from a standard-sized figure (SF) from any other figure as long as the terrain and SF are at the same elevation, so in every example you gave involving Blocking terrain the LOF will be blocked.

The "Great Size" ability, though, specifically says that smaller figures do not block LOF to or from a figure with Great Size. So Ziran can see over Bob to draw LOF to Thanos.

It's different because the rules for how LOF interacts with figures are different than how they interact with Blocking terrain.

Just addressing the question I didn't see others answer:

When you draw a line of fire to any multi-base figure, you choose any one square that the character occupies and treat the line of fire as if it were between the SF's square and that one square. For example....


Above you can see Ziran the Tester, a square of Blocking terrain, an area of Hindering terrain and a character drawing a Line of Fire.

If L tries to target any square of Z that is not occupying hindering terrain, then it will be blocked by the blocking terrain. Any of the squares L can draw a line of fire to occupied by Z is also hindering terrain. Therefore, L would only be able to draw a hindered line of fire to Z.

[Side Note - if Z were not occupying the hindering terrain, then L would be able to get a clear line of fire to Z as he could choose to target a higher elevation - hindering terrain is ignored when a line of fire is across different elevations (unless the character occupies hindering terrain, as Z does in our example)]

So if in your example the B was NOT there, if I drew line of fire to the figure OUT of hindering, does he still get the bonus or not?

He would not get it.
