I'd say there is LOS in the second example of JazzJeff, from the Hillock summit to a Hillock hex, even if LOS crosses another Hillock Summit hex, just for the same reason that a LOS exists from M6 to M10. I think that LOS from Hillock Summit to a Hillock is treated the same way than LOS from Hillock to 0-level.Yes indeed, crest line block LOS to lower levels but in preparation for the scenario, I read the hillock rules (no easy task) and I'm puzzled by F6.6 regarding hillock summits, which are level 1.
Consider the illustration.
Reading F6.6, there seems to be a los as indicated because the summits are treated as an hillock on top of a hillock. Am I wrong or missing something?
Or Hilllock summits are gouverned by different LOS rules from normal level 1 hexes?
