I was looking through the 3rd edition rulebook and came across the invulnerable saves section. I used to think that if a model had a normal save and a different invulnerable save, (ex. normal save of 3+ and invulnerable of 4+) that you HAD to use the invulnerable save to test for an invulnerable test until I read it closely. It says if a model has a normal save and a different invulnerable save, the player must choose which one to use when rolling for an invulnerable test. Does this mean that I can roll for a 3+ armor save instead of the 4+ invulberable save when testing for invulnerability?
