Instant Death – To my literacy skills

As has been pointed out to me, instant death cancels out the effects of feel no pain.  I did know this when I wrote my last account of the Tyranid vs Marine/Wolf battle; but I was focusing on the AP1 and AP2 part of the rule.  And like the scything talons allowing you to re-roll fail ‘to hits’ I completely forgot about the feel no pain-yes you do when hit be a krak missile-for the Tyranid Warriors.  Oh well, we all make mistakes, and I think I’ve had a week of them.
