Double-check my LoS example please

By Tvboy, in Imperial Assault Rules Questions

Working on a future article for Loku, want to double-check to make sure my example of Loku's possible LoS options from his possible starting square in the Battle of Hoth mission are correct, assuming there are no figures blocking his LoS. All the squares occupied by Recon tokens represent squares Loku can see from his spot. Please let me know if I missed any squares or if there are occupied squares that Loku actually shouldn't have LoS to.

Looks good to me, including objects or figures with Health in the blocking spaces.

Figures in some of spaces can of course block LoS (unless abilities allow ignoring them).

Those two spaces on the left of the blocking square, wouldn't those be valid as well, if a probe droid was floating above it?

No, not from Loku's position. You can draw LOS to the blocking space itself if a mobile figure was occupying it, but that still does not allow you to draw LOS though *another* blocking space.

The rule for mobile says "If a figure with mobile occupies a space containing blocking terrain, line of sight can be traced to that figure, spaces can be counted to that figure, and adjacent figures can attack that figure."

It doesn't specify that it needs to be against an edge?

It also does not say anything about the other blocking spaces no longer blocking line of sight.

Trust me, how the rules are interpreted has been confirmed by the developers. (Fizz reproduced my party line admirably so I didn't need to add to it.)

You can draw line of sight into the spaces the target occupies. All other restrictions are still in effect. For example you can't expect that figures no longer block line of sight just because the target occupies a space with blocking terrain. You can still only draw line of sight through the attacker and target.

The same applies to interacting with objects in blocking spaces. If you are adjacent to the blocking space, you are also adjacent to the object in that space and can interact with the object. (The Battle of Hoth, and I think I later came across one in the core campaign as well.)

I made the mistake of thinking of it as a single area, rather than separate spaces.

You can draw line of sight into the spaces the target occupies. All other restrictions are still in effect. For example you can't expect that figures no longer block line of sight just because the target occupies a space with blocking terrain. You can still only draw line of sight through the attacker and target.

Interacting with objects in blocking spaces is obviously possible for exactly that reason, thus the interpretation I laid out, which was confirmed in a private communication. It has not been clarified by FFG in a FAQ (nor a ruling, I think).

Things in blocking spaces have been poorly defined / worded and quite scattered in the RRG, so I'm not surprised that FFG does not want to touch it and make things worse. There are still bits and pieces you can put together, for example the RRG does suggest with some wordings that it is indeed possible to be adjacent to blocking spaces, although normally Counting Spaces cannot be performed into the blocking space and thus adjacent = distance 1 is not quite always true.

Ha! You edited your post above adding something I was about to explore further here!

Also, because of the wording of the rules concerning figures on blocking terrain (under the Massive and Mobile headers in the RRG for those looking) those figures are never adjacent to the spaces next to them. Technically the only exceptions from the normal rules of blocking terrain are that: you can draw line of sight, you can count spaces to them, and an adjacent figure can attack them. They state nothing, however, about its space now being adjacent in general terms.

I don't know if this was by design, but the rules as written suggests that blast and grenades does not work and it is unclear if a melee figure with reach can attack it from one space over. Personally I would allow for all three, but I would not feel like I had the rules backing me in that interpretation.

Actually, come to think of it there are quite a lot of abilities that are not attacks, that does not involve counting space, and instead depend on adjacency, that are thus not possible - that I would otherwise allow in spite of the rules. In fact this starts to look like my very first house rule :)

The "Adjacent figures can attack them" needs that adjacency works or it would be a nonsensical rule. If a figure not on the blocking space can be adjacent to the blocking space the target is on, it should mean that also the blocking space (and the figure on it) is adjacent to the attacker. (The same applies to door rules. They define adjacency one way and assume the other.)

This is one of the tiny details that slowly unravels the figures/objects in blocking spaces rules.

Maybe the technical writer (Clipper) and I could come up with some short rule for it and take it up with the designers. But no promises. It does not seem to be quite as simple as I originally thought, but I'm sure with some thought we could come up with quite compact rules.

Ok, with a few looks into RRG I now remember how this goes.

1) Counting Spaces (and Blocking Terrain) allows Counting Spaces either into or out from blocking spaces, they only disallow them through blocking terrain (and prevent figures from entering blocking terrain). You can also draw Line of Sight either into or out from blocking spaces (but not through blocking terrain).

2) By RAW the edges of blocking terrain spaces are not actually blocking edges .

So I think the only thing needing actual fixing is Adjacency.

There is one issue though. Nothing prevents you from Counting Spaces or drawing Line of Sight through blocking edges, which is clearly not intended. So blocking edges should be added to the Line of Sight rule. Well, scratch that. I just decided (at least for myself) that Blocking Terrain wording actually defines that blocking edges are actually blocking terrain concentrated on the edge of the space, so you cannot Count Spaces or draw LoS through it (just into it - which may still be considered to be an issue). So, everything works as intended.

We just need to get Adjacency to work properly.

Edit:

Adjacent

* Two spaces that share only an edge that is a wall or blocking terrain are not adjacent.

Actually, it seems that the shared edge of the spaces is blocking terrain only when the edge is a blocking terrain edge, so adjacency for blocking spaces works also as written.

OK thanks guys, I'm good now, thanks.

Ok possibly super noob question.

If there were a figure standing on the very left-most token, could Loku still attack him?

One of those lines is going through the figure itself to reach the back corner.

"If either of these lines passes through a wall, figure, or blocking terrain, then the figure

does not have line of sight to the target." RRG 16

Even though one of those lines is going through the targeted figure to his back corner, does that not count as passing through a figure?

They way I've been playing would be yes you can, but my reading for the rules says that one of those lines is passing through a figure, the targeted figure.

You can draw line of sight through the attacker and the target.

Line of Sight, RRG p.16

ยท A figure does not block line of sight to itself. The target figure
also does not block line of sight.
