Attack modifier items?

[[G0KU]Tkdfreak]

Say you buy a nullfire blade and shield breaker; would the negative armor and mana burn both proc at the same time or is it only one of them. And if so which one of the attack modifiers proc? So in this case; the shield breaker or the null fire blade? Thank You

Nullfire Blade isn't an attack modifier. It just doesn't stack with itself or Magebane's Q, so both would apply in this case.

Nullfire stacks with everything but other mana burns.
Thunderclaw and Charged Hammer stack with everything other than each other.
Shieldbreaker, Life Steal*, Harkon's, and Frost do not stack. You must choose one at a time (but you can cycle it between attacks!).

*Abyssal Skull and ability-based Life Steals stack with everything.

Though on a more serious note, what procs first? the -armor or the mana burn, as I believe the mana burn does physical damage, and the - armor would increase the damage by quite a bit.
Though I see no reason to go both these items, it leaves you too squishy.

The negative armor applies before the physical damage from nullfire (90% certain. I'll have EU confirm).

Shieldbreaker:

<onattackingpredamage propagatetoillusions="false" >
	*stuff*
</onattackingpredamage>

Nullfire Blade:

<onattackimpact effectdescription="true" >
	*stuff*
</onattackimpact>
