So this past Saturday I was on my way to beating some demons as I had killed their greater demon by turn 2. However turn 3 they got purple sun off on my slann. He was with a unit of temple guard and would he have gotten a look out sir roll? I don't know if I would have won the game as it took a unit of 20 saurus down to 3. Thanks!
You do get a Look Out Sir roll against Purple Sun. From the main rulebook FAQ: I lost my Slann to this as well in a recent game, and only just found the amended rule.
