I swear that blocking terrain and walls used to go up forever in terms of blocking LOF. Meaning, a wall or piece of blocking terrain on the ground would block LOF between two characters who are elevated. But it seems like this has changed with the new PAC. Am I late to the party and that's the way this has been played? Does this mean that if there was a another piece elevated terrain in the Origins JSA museum map, that a LOF would not be blocked between them by the walls of the museum?

Walls and blocking do go all the way up on indoors, but not on outdoors.

Indoor walls and blocking terrain exist at all levels.

Outdoor walls and blocking terrain exist only at the level of terrain that they are on.

Outdoor Blocking (and Walls) effect LOF at their level only, and yes this is a change with the newest rules.

Yes and no.


Yes, it comes up more and is also specifically spelled out to be clear in the rules since we now have multiple elevations.

No, it was not a recent change, though. Previously, if you had this sort of set-up:

EEE1EE . . B . . EE2EEE

Where E is elevated terrain, the . is grounded terrain, and B is blocking terrain on the ground, 1 and 2 could draw LOF to each other. The blocking terrain is not elevated and did not interfere with elevation LOF... even under the old rules. It just didn't come up very often.

It is not a change with the newest rules. As far as I know, grounded blocking terrain has never blocked a LoF between two elevated figures.

The change with the new rules was that indoors walls and blocking terrain go all the way up.

Thanks for all the replies guys. Changes to the Giant Rules though have now made it so that blocking terrain does not block LOF between two Giants/Colossals right? Same thing with hindering terrain not hindering LOF between two giants/colossals?

would this work on an indoor map?

No. On an indoor map, the blocking terrain would exist at the elevated level, whichever level it is.
