Fighting a Battle
16.0 - Visibility
A thing is visible to a fighter if it is within the fighter’s line of sight.
To determine line of sight to a target, trace a straight line along the ground from the target to the closest point on the fighter’s base. If the line does not cross any high obstacles (7.1), the target is in the fighter’s line of sight and is visible to them.
A fighter is always visible to themselves.
