History

In 0.20 Barachim, a species with the unique +LOS mutation, were added.

Prior to 0.19, the Shadow card existed and could be used to further reduce the player's LOS.

Prior to 0.18, the lantern of shadows existed and could be used to further reduce the player's LOS.

Prior to 0.17, line of sight was circular with a radius of about 8.

In 0.7, the developers made an undocumented change to the LOS. Ranges are circular now, so every spell and ability that reaches a set distance got about two squares lopped off the diagonals. Stealthy characters can now reach their target in 5 squares (instead of 8) at certain angles.
