Tunic reads "When you suffer 1 or more wounds, roll 1 power die for each wound suffered. Cancel 1
wound for each blank you roll."
Ghost armor reads "Spend 1 fatigue to cancel 1 wound being dealt to you."
Mordrag's ability is "Mordrog recovers 1 fatigue each time he is wounded."
The question: when you take a wound, can you roll with the tunic, and then use ghost armor if the wound isn't cancelled? Is suffering a wound different from being wounded (For Mordragin with ghost armor, which is actually a pretty fun combination, although it limits his armor choices).
I think that being wounded means actually returning a heart token, so no super Mordrag combo. But the difference / order of being dealt a wound vs suffering one is unclear. I lean towards ghost armor coming first, but it is more based on seeing the tunic as a last line of defence when all else fails, rather then based on descent logic.
