For our purposes here a ridge is defined as a line from which all ground drops away at a very gradual rate. To represent this on the battle area use a 3 1/2 foot piece of string. This represents the crest of a gradual ridge. A ridge serves to block LOS but confers no combat advantages. If a ridge passes over a hill then the hills still counts as normal for movement penalties, LOS, and combat mods. A ridge can be as straight or as curvy as you wish, but it is best to keep the curves fairly gradual or it could lead to confusion and arguments.
A unit that has any open edge adjacent to the ridge can see over it, and likewise can be seen. To avoid any confusion always clarify with your opponent your intentions. Large or colossal units and cavalry that are within 2.5" of the Ridge are treated as though they were adjacent.
|In this photo the Dark Elves are all to the left of the ridge and cannot see any of the Hawkskold troops except the Longbowmen who are between the hills and have stated that they are on the ridgeline.|
|In this diagonally running ridge The Longbowmen are visible as they have stated they are on the ridge line and the two other Hawkshold units that are on the same side of the ridge as the Dark Elves are also visible.|
