hellhound breath

By Headspin, in Descent: Journeys in the Dark

on a map where part of the dungeon forms a rectangle with 3 spaces on the short side of the rectangle, will the hellhound breath fired at the top wall affect spaces on the bottom of the rectangle, effectively going through empty space.

D is dungeon floor, is X safe from breath attack at B fired south?

Get the FAQ , it is covered in detail there.
I think the answer is no in this case, because when the breath template is laid on the table the first (and second) row will be entirely off the dungeon.

However, in the case below, the X space will not be safe from B:

The breath path, starting immediately south of B, will be SE-S-SW-W-W and at all times will be under the template.
