The line of sight example given on p.12 of the rules for the base game says Jain Fairwood is not able to attack the zombie with a ranged weapon because there is no line of sight.
According to the line of sight rules, there is line of sight if a straight line can be drawn from any corner of the attacker's space to any corner of the target space. If the line passes through a corner of a blocked space, the target space is still considered to be in line of sight.
The example shows there is no line of sight by looking at two different corners of the attacker and target spaces. However, if I were to draw a line from the lower left-hand corner of the attacker space to the lower right-hand corner of the target space, the line passes through the corner of a blocked space but not through a blocked space. Therefore, I believe there is actually line of sight for Jain Fairwood in this example and a ranged attack is possible. Can anyone check my reasoning on this and see if the rulebook is in error?
