The non-combat Incident card "A Terrible Nightmare" inflicts four wounds on each hero, ignoring armor, reduced by surges rolled on two black dice.
Could a hero prevent any these wounds by using ghost armor or elven cloak or the like?
Especially Ghost armor would seem a bit unfair, since fatigue is always immediately restored after the encounter, so that would be a complete protection (except for the poor few heros that have less than four fatigue maximum).
Thoughts?
Edit: Same question is valid for the damage caused by a Tavern brawl.
