If I place something like a stack of crates or a bookcase infront of a window so the game graphics make it look blocked off, does the game 'see' that as blocking LOS from outside for spell/arrow attacks?
Also, does the game's LOS mechanism account for different levels? Eg. If I'm upstairs and away from a window can people at ground level see me anyway? (I mean for targeting purposes, I know people can see my character's name on the screen).
I'd rather not find out by logging in to find a dead character sometime

Thanks.
