Example: swordsman (sight 4) gets a -1 value added. After trigger cond. Is met, the stats sheet (popup) will show 4-1 which equals 3. At the beginning of each new turn, before the swordsman has moved, he sees 4 tiles away. Upon movement, he can only see 3 tiles away (4-1=3 takes effect)
Could anyone else try it for conformation, just in case I'm accused of lying (or worse.....treason!)
