Page 12 of the rulebook says: "Starting with the space adjacent to the attacker (of his choice), count the number of spaces to the target space."
If one of the adjacent spaces is blocked (figure, obstacle etc.) may I start to count through this space?
As an example, take the picture "Line of sight example" on page 12 of the rulebook. Example 1 shows that Leoric has line of sight to the minion zombie and may attack with his ranged weapon. If he starts to count the distance, may he start with the adjacent obstacle field (only 2 spaces to the target) or not (otherwise 3 spaces)?
