I have a problem, yesterday there was a discussion in this situation. The blue line is a valid line of sight to Truthseer Kel?

no

No It´s not valid against "borders":

interesting.

so in 9. D is allowed to shot at A? looks strange.

In 9. A can shoot B or D

But what i think is more strange is that 6. is not valid but 7. is.

No It´s not valid against "borders":

I know that, but Truthseer Kel have this ability: " Figures and obstacles do not block your line of sight. Doors still block your line of sight as normal ", then only the doors block my line of sight.

But you have the "border" of the tiles blocking, so I should say no.

From the manuel:

If the line passesthrough the edge of a map tile, a door, or a blocked space

(a space containing a figure or obstacle), the target space is not in line of

sight

In this case you are:

ok: blocked space (a space containing a figure or obstacle)

not ok: If the line passesthrough the edge of a map tile, a door,

But you have the "border" of the tiles blocking, so I should say no.

Thanks alot for your response. Finally my doubt is cleared.
