Hi Ian, nice video! Thanks for the explanation on the LOS along slope. The correction on the adjacent hex LOS along slope crest is a manifest how easy to check the LOS in an incorrect manner. However, I find the explanation a bit on the basic side (it's alright in such a short precise video). My main confusion arises from the following two sentences in rule 6.2 with respect to tracing LOS from one hill/ slope to another hill/ slope:
6.2.2 Line of Sight along slopes. Line of Sight along slopes applies when the two hexes are at different heights. LOS may only be traced along slopes if the higher of the two units is in a crest hex. If the higher unit does not occupy a crest there is no LOS.
Any hex containing a crest line that is crossed by the LOS (other than a crest line in the hex occupied by the higher unit) also creates a blind hex in the adjacent hex behind it, unless the difference between the height of the two units is less than or equal to the distance
If you can talk about them in your next video, that will be great.
