I’m not sure if you’re purposefully misinterpreting this rule but it does not state MW are their own attack.
Some attacks can inflict mortal wounds either instead of, or in addition to, the normal damage. If, when a unit is selected to shoot or fight, more than one of its attacks that target an enemy unit have such a rule, all the normal damage inflicted by the attacking unit’s attacks are resolved against that target before any of the mortal wounds are inflicted on it.
It says: “Some attacks can inflict mortal wounds either instead of, or in addition to, the normal damage.”
This clearly indicates they are part of that attack not separate. Sure the MW might be in addition to the normal damage but that doesn’t mean it’s separate from the attack itself nearly separate from the normal damage of that attack.
“all the normal damage inflicted by the attacking unit’s attacks are resolved against that target before any of the mortal wounds are inflicted on it.”
This simply instructs you to follow steps 4 and 5 of making an attack (allocate followed by inflict) for MWs after doing so for the normal damage.
That doesn’t actually separate them from the attack it simply wants you to instead of doing: - 1: Hit - 2: Wound - 3: Save - 4: Allocate - 5: Inflict
It wants you to:
You claim:
It mentions that you have to resolve all attacks of a unit before applying any mortal wounds,
No it doesn’t. It actually says you need to resolve all the damage from those attacks before resolving the MWs damage (splitting step 4 and 5 into two parts).
all the normal damage inflicted by the attacking unit’s attacks are resolved against that target before any of the mortal wounds are inflicted on it.
Then you stare:
besides the steps for an attack sequence doesn't list a step apply mortal wounds.
Indeed they don’t but the MW rules do tell you how to include them into the base rules
Even the rules for mortal wounds says to treat like they were their own attacks.
False as above. If you can quote where this is stated emphatically I’d be curious to see it.
So no they are not part of the original attack and I actually don't see why anyone would call it a gray area.
The opening statement for MW rules literally says: “Some attacks inflict MW” thus indeed MWs are part of some attacks not separate as you would have us believe.
