I have two rules conundrums regarding the Feel No Pain special rule.
#1: If a model has the Eternal Warrior special rule, it is thereby "immune to the effects of Instant Death." Does this mean that FnP can be taken against ID wounds on a model that has Eternal Warrior?
#2: If a model with a Shadowfield fails its 2++ save, the rules for a Shadowfield state that "if this save is ever failed, the Shadowfield is destroyed." However, under the rules for FnP, it states, at the end, that if the FnP save is made, "the unsaved wound is discounted - TREAT IT AS HAVING BEEN SAVED." So, does this mean that the Shadowfield is still intact if you make your FnP save??
