Reciprocal line of sight exception ?

[Stunt]

Hi there,

 

Line of sight rules say: "If at least one of the sight lines between two objects is unblocked, the objects have LoS to each other. If all the sight lines are blocked, the two objects may not have LoS to each other."

So reciprocal line of sight it seems.

 

Shadow rules say: "When drawing sight lines from one model to another, if either model is in the Shadow of terrain with Height equal to or greater than the Size of that model (even partially), any sight lines that pass through the terrain generating that Shadow are blocked."

And: "When drawing sight lines, a model standing on terrain that is casting a Shadow ignores that terrain (and its Shadow) if any single sight line drawn between the two objects passes through 1" or less of that terrain."

This last exception and the way it's written makes it feel like only the guy (Alice) on top of the terrain can ignore that terrain and its shadow, thus giving it line of sight to somebody (Bob) standing down in that terrain's shadow. But the exception not applying to Bob would mean he does not have line of sight to Alice.

Hence not reciprocal ?

 

Is it just a misunderstanding or there is indeed an exception to the reciprocal line of sight rules ?

 

Thanks for your help !

Shadow is the most obvious reason to show that whilst the sight lines drawn between the 2 models are the same, the line of sight outcomes can be different. I can't think of another example, but I wouldn't be surprised if some models do have an ability that also chnaged the LOS outcome. 

So I don't think Line of sight is strictly reciprocal, its just that in 99% of the cases both models would get the same outcome, so if one has LOS, the other has LOS.

Thanks for your quick answer

There are also various abilities and effects that allow models to draw line of sight from other places on the table (from markers or from other models).  Those will also create non-reciprocal line of sight situations.

Even in this case, one could argue that since one of the lines of sight is unblocked, they both have LOS since the main rules states "If at least one of the sight lines between two objects is unblocked, the objects have LoS to each other. 

That rule doesn't indicate that it has to be unblocked for both models for it to be true. And in the case you mention, there is one sight line that is unblocked (from the model on top to the model below).

However, it is a strange interaction of rules so best to discuss how your group wants to play it.
